Rain, rain go away, come again some other day.

The days of wishing rain away have long since passed, amid the reality of a wetter world, particularly during hurricanes in the North Atlantic.

In a recent study published in the journal Nature Communications, Kevin Reed, Associate Professor and Associate Dean of Research at the School of Marine and Atmospheric Sciences at Stony Brook University, compared how wet the hurricanes that tore through the North Atlantic in 2020 would have been prior to the Industrial Revolution and global warming.

Reed determined that these storms had 10 percent more rain than they would have if they occurred in 1850, before the release of fossil fuels and greenhouse gases that have increased the average temperature on the planet by one degree Celsius.

The study is a “wake up call to the fact that hurricane seasons have changed and will continue to change,” said Reed. More warming means more rainfall. That, he added, is important when planners consider making improvements to infrastructure and providing natural barriers to flooding.

While 10 percent may not seem like an enormous amount of rain on a day of light drizzle and small puddles, it represents significant rain amid torrential downpours. That much additional rain can be half an inch or more of rain, said Reed. Much of the year, Long Island may not get half an inch a day, on top of an already extreme event, he added.

“It could be the difference between certain infrastructure failing, a basement flooding” and other water-generated problems, he said. The range of increased rain during hurricanes in 2020 due to global warming were as low as 5 percent and as high as 15 percent.

While policy makers have been urging countries to reach the Paris Climate Accord’s goal of limiting global warming to 2 degrees Celsius above the temperature from 1850, the pre-Industrial Revolution, studies like this suggest that the world such as it is today has already experienced the effects of warming.

“This is another data point for understanding that climate change is a not only a challenge for the future,” Reed said. It’s not this “end of the century problem that we have time to figure out. The Earth has already warmed by over 1 degrees” which is changing the hurricane season and is also impacting other severe weather events, like the heatwave in the Pacific Northwest in 2021. That heatwave killed over 100 people in the state of Washington.

Even being successful in limiting the increase to 2 degrees will create further increases in rainfall from hurricanes, Reed added. As with any global warming research, this study may also get pushback from groups skeptical of the impact of fossil fuel use and more carbon dioxide in the atmosphere.

Reed contends that this research is one of numerous studies that have come to similar conclusions about the impact of climate change on weather patterns, including hurricanes.

“Researchers from around the world are finding similar signals,” Reed said. “This is one example that is consistent with dozens of other work that has found similar results.”

Amid more warming, hurricane seasons have already changed, which is a trend that will continue, he predicted.

Even on a shorter-term scale, Hurricane Sandy, which devastated the Northeast with heavy rain, wind and flooding, would likely have had more rainfall if the same conditions existed just eight years later, Reed added.

Reed was pleased that Nature Communications shared the paper with its diverse scientific and public policy audience.

“The general community feels like this type of research is important enough to a broad set of [society]” to appear in a high-profile journal, he said. “This shows, to some extent, the fact that the community and society at large [appreciates] that trying to understand the impact of climate change on our weather is important well beyond the domain of scientists like myself, who focus on hurricanes.”

Indeed, this kind of analysis and modeling could and should inform public policy that affects planning for the growth and resilience of infrastructure.

Study origins

The researchers involved in this study decided to compare how the 2020 season would have looked during cooler temperatures fairly quickly after the season ended.

The 2020 season was the most active on record, with 30 named storms generating heavy rains, storm surges and winds. The total damage from those storms was estimated at about $40 billion.

While the global surface temperature has increased 1 degree Celsius since 1850, sea surface temperatures in the North Atlantic basin have risen 0.4 to 0.9 degrees Celsius during the 2020 season.

Reed and his co-authors took some time to discuss the best analysis to use. It took them about four months to put the data together and run over 2,500 model simulations.

“This is a much more computationally intensive project than previous work,” Reed said. The most important variables that the scientists altered were temperature and moisture.

As for the next steps, Reed said he would continue to refine the methodology to explore other impacts of climate change on the intensity of storms, their trajectory, and their speed.

Reed suggested considering the 10 percent increase in rain caused by global warming during hurricanes through another perspective. “If you walked into your boss’s office tomorrow and your boss said, ‘I want to give you a 10 percent raise,’ you’d be ecstatic,” he said. “That’s a significant amount.”

Ecstatic, however, isn’t how commuters, homeowners, and business leaders feel when more even more rain comes amid a soaking storm.

Over the past 75 years, Brookhaven National Lab (BNL) in Upton has become an international hub for innovative research and problem-solving. Their hard work has led to advancements in energy, medicine, physics and more, as well as seven Nobel Prizes.

This year, the Long Island Museum in Stony Brook will celebrate the lab’s myriad achievements and explore their deep roots in the area. The new exhibit, titled Atoms to Cosmos: The Story of Brookhaven National Laboratory, opens April 21.

BNL and the Long Island Museum started working on ideas for a future exhibition back in 2018 with plans to open in April of 2020. But as with other museums, the pandemic led to a halt in operations.

In some ways, the rescheduled timing of the exhibit is better than their initial plans.

“While the exhibition was temporarily shelved, both the lab and the museum wanted very much to still make it happen. We had done so much work in advance and preparation for it in 2020, and so we really wanted to get back to this opportunity,” said Joshua Ruff, Deputy Director and Director of Collections and Interpretation for the Long Island Museum. “We are especially pleased we were able to do it now, as it fits nicely with the lab’s 75th anniversary celebration.”

Brookhaven National Laboratory was founded in 1947 at the former site of the U.S. Army’s Camp Upton, becoming the first large research facility in the Northeast. At the time, they were exploring peaceful ways to utilize atomic energy. 

“The BNL site has been in federal ownership since 1917 when it became the location of Camp Upton. Before that, the site was used for the cordwood industry and there was a small farm near the eastern edge of what is now the lab,” explained Timothy Green, BNL’s Environmental Compliance Section manager. “After World War I, all of the buildings were sold at auction and the site sat empty until around 1934, when it was declared the Upton National Forest and the Civilian Conservation Corps started planting trees. At the end of World War II [and a second period as Camp Upton], the land was transferred to the Atomic Energy Commission and became Brookhaven National Laboratory.”

It took some time for local residents to adjust to having a laboratory in the area, Ruff said.

“The lab has often been misunderstood in its past, in fact from its origins. Many Suffolk County residents were not entirely sure that atomic research was safe, nor did they fully understand the relevance and significance [of that research] to their lives,” he explained. “The lab devoted years of hard work and financial resources to strengthen public dialogue and communication, which the exhibition details.”

Today, the lab employs almost 3,000 people and spans 5,320 acres.

The exhibit is co-curated by Joshua Ruff and Long Island Museum curator Jonathan Olly. They’ve included more than 140 items that showcase the lab’s growth and varied discoveries from the 1950s to the present day. The Smithsonian Museum of American History in Washington is lending four of the objects, including a 1,000-pound, 94-inch square magnet lamina from the Cosmotron, BNL’s first major particle accelerator. 

Another 40 objects are coming directly from the lab. Their contribution includes equipment from their facilities, personal belongings of former director Maurice Goldhaber, and “Atoms for Peace,” a famous painting that came to symbolize the lab’s work in its early years.

“A lot of the scientific research at BNL over the years has involved [developing] and testing cutting edge technologies. When these machines are no longer useful they’re usually recycled. Fortunately we do have two examples in the exhibition of early PET (Positron Emission Tomography) scanners, one from 1961 and another from 1981,” Olly said. “In the case of these early machines, the focus was on the brain — the machines used radiation sensors arranged in a ring to produce a picture of a slice of your brain. Brookhaven scientists have used this PET technology (specifically the PETT VI scanner in the exhibition) in studying drug and alcohol addiction, eating disorders, ADHD, aging, and neurodegenerative disorders. The 1961 version is a prototype that was never used on patients.”

Also on view are an original chalkboard from the Graphite Research Reactor that still has writing on it; a 7-foot window from a bubble chamber that helped track the paths of atomic particles; and a detector that aided BNL chemist Raymond Davis Jr. in his Nobel Prize-winning neutrino research. 

Recently, the lab was a part of the ongoing effort to study and contain COVID-19. The exhibit will include a model of the virus, with the familiar spiky shape that’s become commonplace since the pandemic began.

“Scientists at the lab’s National Synchrotron Light Source II worked on imaging the virus and the proteins … that allowed it to attach to human cells. At the same time, BNL computer scientists began developing algorithms to evaluate existing chemicals and drugs that could potentially prevent infection. One past experiment by [BNL biophysicist] William Studier, the T7 expression system, ended up being critical to the rapid development of two of the vaccines,” Green said.

Both the Long Island Museum and BNL staff hope that visitors to the exhibit come away with a deeper interest in science and an appreciation for the lab’s work.

“There are 17 national laboratories scattered throughout the United States, and Long Islanders can be proud to have one in their backyard. Long Island children have been inspired to pursue careers in science as a result of attending educational programs at the lab during public visitor days dating back to the 1950s. And the lab is invested in addressing our real-world problems, whether the dangers posed by DDT on Long Island in the 1960s or COVID now. This summer BNL should be resuming their “Summer Sundays” visitor program, and I encourage everyone to visit the lab, walk around, talk to staff, and get a glimpse of our scientific present and future,” Olly said.

Atoms to Cosmos: The Story of Brookhaven National Lab is on view now through Oct. 16 in the Long Island Museum’s History Museum and Visitor Center’s Main Gallery, 1200 Rt. 25A, Stony Brook. Regular museum hours are Thursday through Sunday from noon to 5 p.m. Masks are required at this time, though health and safety guidelines are subject to change Admission is $10 for adults, $7 for seniors, and $5 for students 6 to 17 and college students with I.D. Children under six are admitted for free. Tickets are available at the door; pre-registration is not required. For more information visit longislandmuseum.org or call 631-751-0066.

Do the birds on the Galapagos Islands, with their unique coloration, differently shaped beaks and specific nesting places, have anything to do with the cancer cells that alter the course of human lives?

For Mehdi Damaghi, Assistant Professor in the Department of Pathology at the Renaissance School of Medicine at Stony Brook University, the answer is a resounding, “Yes.”

Damaghi uses the same principles of evolutionary biology to understand how cancer, which resides within human genes, works to adapt, as it tries to win the battle to survive.

“What we try to understand is the Darwinian principals of cancer,” said Damaghi. Cancer “adapts and reprograms themselves” to their environment to survive.

Damaghi, who arrived at Stony Brook four months ago from Moffitt Cancer Center, plans to address numerous questions related to cancer. He recently received a $4 million grant from the Physical Science in Oncology program (PSON) through the National Institutes of Health/ National Cancer Institute. Working with cancer biologists, clinicians, and computational scientists, he plans to define and understand cancer’s fitness.

“We are trying to study the core evolution of cancer cells and the normal stroma around them,” said Damaghi. “We are looking at the evolution of the tumor and some of the host cells.”

Cancer biologists are trying to build mathematical and theoretical models to explore the playbook cancer uses when confronted with threats, either in the form of a body’s natural defenses against it or from therapies against which it can, and often does, develop resistance.

Treating cancer could involve using adaptive therapy, which could enable people to control and live with cancer longer, Damaghi suggested.

In studying cancer’s phenotype, or the way the disease is expressed and survives, he hopes to understand factors in the microenvironment. Many cancers, he reasons, become more problematic as people age. Indeed, centuries ago, cancer wasn’t as prevalent as it is today in part because life expectancy was shorter.

Damaghi also has an evolutionary model to explore metastasis, in which cancer spreads from one organ or system to other parts of the body. He is looking at the earliest stages of breast cancer, to see what factors some of these cancers need or take from the environment that enables them not only to develop into breast cancer, but also to spread to other systems.

Through the microenvironment, he is looking for biomarkers that might signal a potential tumor development and metastasis long before a person shows signs of an aggressive form of the disease.

“We look at the tumor as a part of a whole ecosystem that can have different niches and habitats,” he said. “Some can be hypoxic and oxidative, and others can be like a desert on Earth, where not much grows and then cancer evolves.”

Damaghi challenges cells in a culture or organoids, which are miniature, three-dimensional live models of human cells, with different microenvironmental conditions to see how they respond. He exposes them to hormones, immune cells, and hypoxic conditions.

“We try to understand what is the adaptation mechanism of cancer to this new microenvironment and how can we push them back to the normal phenotype,” he said.

Like other scientists, Damaghi has demonstrated that many of these cancer cells use sugar. Removing sugar caused some of the cancer to die.

Increasing the survival for patients could involve knowing what kinds of micro-environments cancer uses and in what order. Deprived of sugars, some cancers might turn to amino acids, dairy or other sources of food and energy.

Damaghi thinks researchers and, eventually, doctors, will have to approach cancer as a system, which might have a patient-specific fingerprint that can indicate the resources the disease is using and the progression through its various diseased stages.

Choosing Stony Brook

Damaghi appreciates the depth of talent in cancer sciences at Stony Brook University. He cited the work of Laufer Center Director Ken Dill and Cancer Center Director Yusuf Hannun. He also suggested that the Pathology Department, headed by Ken Shroyer, was “very strong.”

For their part, leaders at Stony Brook were pleased to welcome, and collaborate with, Damaghi. Hannun suggested Stony Brook recruited Damaghi because his research “bridges what we do in breast cancer and informatics.”

Shroyer, meanwhile, has already started collaborating with Damaghi and wrote that his new colleague’s focus on breast cancer “overlaps with my focus on pancreatic cancer.”

To conduct his research, Damaghi plans to look at cells in combination by using digital pathology, which can help reveal tumor ecosystems and niches.

He also appreciated the work of Joel Saltz, the Founding Chair in the Department of Biomedical Informatics. “In the fight against cancer, we all need to unite against this nasty disease,” Damaghi said. “From looking at it at different angles, we can understand it first and then design a plan to defeat it.”

Originally from Tehran, Iran, Damaghi is the oldest of five brothers. He said his parents encouraged them to explore their curiosity.

Damaghi, whose wife Narges and two daughters Elissa and Emilia are still in Tampa and hope to join him before long, has hit the ground running at Stony Brook, where he has hired three postdoctoral researchers, a lab manager, four PhD students, two master’s candidates, and three undergraduates.

Damaghi is inspired to conduct cancer research in part because of losses in his family. Two grandparents died from cancer, his aunt has breast cancer, and his cousin, who had cancer when he was 16, fought through the disease and is a survivor for 20 years.

Damaghi bicycles and plays sports including soccer. He also enjoys cooking and said his guests appreciate his Persian kebobs.

As for his arrival in Stony Brook, he said it was “the best option for me. It’s a great package and has everything I need.”

The black box has a blue spot.

Often considered so mysterious that it has been called “the black box,” the brain has a small cluster of cells called the locus coeruleus (LC), or blue spot because it appears blue.

The LC is the predominant source of the neurotransmitter noradrenaline, which plays numerous roles, including triggering the “fight or flight” response, sleep/wake regulation and memory.

Recently, Cold Spring Harbor Laboratory Associate Professor Stephen Shea and his post doctoral researcher Roman Dvorkin demonstrated that the LC was involved in normal maternal social behavior. In the publication Journal of Neuroscience, they demonstrated that surrogate mothers had a spike in this neurotransmitter just at the time when they retrieved young pups that had rolled out of the nest.

“Most of the research on noradrenaline and the LC has been involved in non-social behavior,” said Shea. Researchers have recorded it extensively during “cognitive tasks and memory formation.”

The evidence for its involvement in social behaviors has been more indirect. With the exception of a study 35 years ago that made a few recordings in cats, the current research is the “first time anyone has recorded” the LC during a more normal social behavior, Shea said.

Research on this blue spot could prove valuable in connection with understanding and treating a wide range of diseases and disorders. Noradrenaline (NA) is “one of the systems that is disturbed in anxiety and depression,” Dvorkin said. It also may be involved in other diseases, like autism. Scientists have conducted research on the LC and ADHD, Parkinson’s disease and Alzheimer’s disease, Dvorkin explained.

Some studies have also linked Rett syndrome, for example, which is a rare inherited genetic disorder that affects mostly girls and can alter the ability to speak, walk and eat, to lower levels of noradrenaline.

“There’s evidence that the LC has pathology in Mecp2 mice,” said Shea, referring to a gene traced to Rett. “We are working on that directly.”

Researchers believe studying the structure of the LC could lead to diagnostics and therapeutics for some of these diseases. Dvorkin suggested that this kind of research is “important to see how it works under normal, awake conditions.”

Monitoring the release of this neurotransmitter during a typical social behavior among female mice provides a context-connected understanding of its potential role.

“When people are studying this, they often use investigator-contrived tasks,” Shea said. “This is the system that preexisted for mice to use for other purposes.”

Shea has done earlier work with the LC, particularly as the sense of smell is so prominent in social interactions for mice. He demonstrated that anesthetized mice exposed to the scent of an unfamiliar mouse react as if they have a familiarity with the mouse. 

She believes the LC initiates sensory plasticity or sensory learning. NA can affect the sensory responses in parts of the brain that carry information, creating a stored memory. While his extensive work offers some clues about the role of the LC in mice, all vertebrates have the LC in their brain stems, including humans.

Shea said other research has demonstrated the involvement of the LC in cognitive tasks and memory formation, including during periods of sleep and wakefulness.

Blocking the release of noradrenaline is challenging in part because it is compact and the cells in the brain interact with so many of their neighbors, which makes turning on or off a specific signal from one region especially challenging.

At the University of Washington, Richard D. Palmiter and S.A. Thomas published a visible and definitive paper in 1997 in the journal Cell that brought the LC to other researcher’s attention.

These researchers created complete knockout mice, where they found that rodents lacking noradrenaline were “really bad mothers,” according to Shea.

In their research, Dvorkin and Shea used optogenetics and chemogenetics to inactivate the LC and the release of noradrenaline.

Future experiments

The next step in this research could involve understanding the relative importance of the signal from the LC and noradrenaline.

In typical life settings, mice and other vertebrates confront competing signals, in which a pup rolls out of the nest at the same time that one of their many predators, like a hawk or other bird is circling overhead.

“That could be a next step” in this research, said Dvorkin.

Dvorkin believes it is possible to increase or decrease the threat level for mice gradually, in part because mice learn quickly when the threat is not real or what to avoid if the threat is too risky.

Shea is also looking more closely at courtship behavior.

The LC could be involved in sexual selection and in dominance hierarchies, enhancing the aggressive behavior of alpha males towards less dominant males. 

“We see big signals associated with events in courtship, including when the female and male begin to mate,” said Shea.

A resident of East Northport, Dvorkin lives with his wife Paolina and their nine year-old son Adam, who is in third grade at Pulaski Road School.

Originally from Afula in northern Israel, Dvorkin has been working in Shea’s lab for over five years. Outside the lab, he enjoys spending time with his family, taking pictures, and swimming at the JCC.

Dvorkin has enjoyed his work at CSHL, which he described as a “great experience in a beautiful place,” where he can appreciate the quiet and where he has received considerable support.

In the future, he’d like to apply his expertise in working on neuronal cell cultures and behaving animals to address translative questions, such as neurodegeneration.

In 1997 I sent Leah Dunaief several essays that I called Life Lines and I asked her if she thought these might be of interest to the readers of her new newspaper, the Village Times.  

About a month later she replied and said she retrieved my packet from her pile of correspondence and liked my essays and thus began a 25 year association and more than 400 columns of Life Lines as her newspaper chain grew in number across the North Shore of Long Island.  

My aim was to inform my readers of the importance of science in our lives. I am a professor, now retired, who taught in Canada (Queen’s University), UCLA, and Stony Brook University as well as holding visiting professorships over the years in San Diego State University, the University of Utah, the University of Minnesota, and Tugaloo College  in Mississippi.

I have also taught twice on Semester at Sea a floating campus that sales eastward or westward around the world for a semester with 500 students. I have taught also in programs for a federal program to raise science literacy in former USSR republics, including Samara —  on the Volga River, and Tbilisi in former Soviet Georgia. I have mentored 6 students through their PhDs in my laboratories and have published 15 books on genetics, the history of genetics, the eugenics controversy, and science and society conflicts. I love to teach and have taught thousands of students at UCLA and Stony Brook University in a course titled Biology 101-102 Biology – A Humanities Approach.

I argued that a knowledge of science and its history and its application to society is important in showing how science has greatly reduced infant mortality, greatly increased life expectancy, eliminated most communicable disease, and restored health to millions of people through its applications to our food industries, pharmaceutical industries, and public health programs.  

It gives us greater control over our lives and allows a person like me to live more than 90 years. I will be celebrating my 91st birthday in July and I am grateful that I have lived an examined life, avoided alcohol and other harmful agents in my life and have insights into how life works that are worth sharing.  

I read widely, love the arts and humanities, consider science to be part of the liberal arts education we should extend past K-12 to college level programs that make us informed citizens in a democracy and parents able to make informed decisions about their children’s well-being rather than relying on political ideologies or religious traditions first introduced two or three thousand years ago as guides for how to protect ourselves and our families.  

Science allowed me to understand how life works. I can follow it from atoms to molecules, macromolecules, cell organelles, cells, tissues, and organs. From there I can extend it to the population, the diversity of life on earth, and the importance of human stewardship of that life by informed ways using the earth’s bounty, protecting it from pollution, avoiding erosion, preventing desert formation, and preventing discharges of carbon dioxide from the fuels we use that lead to climate change that can flood our coastal cities and bring chaotic weather patterns around the world.  

I thank Leah Dunaief and her son Daniel for the many articles on science that inform North Shore readers of what is going on in our universities, research institute, and industries on Long Island. I thank you readers who have written to me, stopped me when I shopped in the local stores, or offered different points of view to which I would respond.  

I have lived an examined life, selected, as an Epicurean, from the best minds and writing of Western civilization. I am grateful for the gift of life to have lived this long. But now in my 90s I lack the energy I had ten years ago and have decided to use the time remaining in my life to work on my unpublished manuscripts and get them published or place them to print-on-demand programs on the internet. I much appreciate you, my reader, for the pleasure of having this opportunity,

This is the first in a two-part series on Long Island’s water supply.

When thinking about Long Island’s groundwater supply — its drinking water aquifers — it is helpful to visualize a food you might eat while drinking water — say, a three-tiered, open-faced turkey sandwich — a slice of cheese on top, a juicy, thick tomato disk in the middle, a slice of turkey on the bottom, all resting on a piece of hard, crusty bread. 

Well, substitute the Upper Glacial Aquifer for the cheese, the thicker Magothy Aquifer for the tomato, the Lloyd Aquifer for the turkey, and a “basement of bedrock” for the bread and you’ve got Long Island’s tiered groundwater system. It is this collection of groundwater aquifers — these sections of the sandwich — that are the sole source of water for all the uses Long Islanders use water for. Hydrologists estimate there’s about 90 trillion gallons of water contained in Long Island’s groundwater supply.

Our sandwich model described above is not fully accurate in that there is another layer called the Raritan Clay formation separating the Magothy and Lloyd Aquifers. This clay layer, about 200 feet thick, retards water movement (for a number of reasons water moves painfully slow through clay) and is referred to as an aquitard. So, in our sandwich model let’s make the thin but impactive clay formation a layer of mustard or mayonnaise. With the exception of this clay-confining layer, Long Island is essentially a million-acre sandpile whose geology is generally distinguished by subtle changes in the composition, texture, and porosity of its geological materials — varying mixtures of silt, clay, sand, gravel and cobbles which affects rates of water transmissivity or movement.

The basement of bedrock (the bread in our sandwich) that underlies all of Long Island is metamorphic rock estimated to be about 400 million years old. It slants from the northwest to the southeast dipping at about 50 feet to the mile. So, while the thickness of the freshwater aquifers in northwest Queens is only a few hundred feet, it is approximately 2,000 feet thick in western Southampton.

On the North and South Forks and the south shore barrier islands, freshwater doesn’t extend all the way to bedrock as it does in Nassau County and much of western and central Suffolk County. It is shallowest on the barrier islands, the freshwater lens extending down only several dozen feet. 

On the North Fork it goes a little deeper before the water becomes salty and it is deepest on the wide South Fork where the freshwater lens extends downward about 550-600 feet. The depth of the aquifer is influenced by how many feet above sea level the water table is. There’s a hydrological formula, called the Ghyben-Herzberg principle, that states for every foot of water above sea level there’s 40 feet of freshwater beneath.

The water in the groundwater aquifers isn’t stored in large subterranean pools or caverns, as it is in some other places in the country with markedly different geology, Rather, the water is situated between the tiny, interstitial spaces existing between the countless sand particles that collectively make up Long Island. Given this, it is not surprising that groundwater flows (under the influence of gravity) slowly downward and sideways (depending where in the aquifer the water is located) moving on the order of just a few feet a day at most but typically in the ballpark of about one foot per day. 

It takes dozens to hundreds to thousands of years for water to move through the system, all depending where it first landed on the island’s surface. Water pumped from the seaward edge of the lowest aquifer — the Lloyd Aquifer — may have fallen as rain many years before the beginning of the ancient Greek Empire.

In the late 1970’s several governmental studies helped us to better understand some of the basics as to how the groundwater system works. One of the important takeaways from this research was that it is the middle half to two-thirds of the island that is most important for recharge — this segment is known as the “deep-flow recharge area” because a raindrop that lands here will move vertically downward recharging the vast groundwater supply. 

The middle of this area is knows as the “groundwater divide”; a water drop that lands to the south of the divide will move downward and then laterally in a southern direction discharging into one of the south shore bays or the salty groundwater underneath the Atlantic Ocean while a drop to the north will move eventually into Long Island Sound or the sandy sediments beneath it.

Hydrologists have determined that for every square mile of land (640 acres) an average of about two million gallons of rain water lands on the surface with about one million gallons recharging the groundwater supply on a daily basis. What happens to the other one million gallons? It evaporates, runs off into streams and other wetlands, or is taken up by trees and other plants that need it to sustain life processes such as transpiration (a large oak tree needs about 110 gallons of water daily to survive). 

In contrast, raindrops that land in locations nearer to the coasts such as in Setauket, northern Smithtown, southern Brookhaven, Babylon, or other places along the north and south shores don’t become part of the vast groundwater reservoir; instead, after percolating into the ground the water moves horizontally, discharging either into a stream that flows to salty water or into the salty groundwater that surrounds Long Island. These landscape segments are referred to as “shallow-flow recharge areas.”

The higher elevations along the Ronkonkoma Moraine (the central spine of Long Island created by glacial action about 40,000 years ago) are also the highest points in the water table although the water table elevation contours are a dampened expression of the land surface. So, in the West Hills region of Huntington where Jayne’s Hill is located, the highest point on Long Island topping out at a little more than 400 feet, the elevation of the water table is about 80 feet above sea level. 

Below the water table is the saturated zone and above it the unsaturated zone where air, instead of water, exists in the tiny spaces between the sand particles (in the Jayne’s Hill case the unsaturated zone runs about 320 feet). It is the water (more precisely its weight) in the higher regions of the saturated zones that pushes on the water beneath it, driving water in the lower portions to move at first sideways or laterally and then to upwell into the salty groundwater under the ocean. Due to the weight of the water the freshwater-saltwater interface is actually offshore on both coasts, meaning you could drill from a platform a mile off Jones Beach and tap into freshwater if you were to drill several hundred feet down.

A wetland forms where the land surface and water table intersect. It may be Lake Ronkonkoma, the Nissequogue or Peconic River, or any of the more than one hundred streams that drain the aquifer discharging into bays and harbors around Long Island. So when you’re gazing at the surface of Lake Ronkonkoma you’re looking at the water table — the top of the Long Island groundwater system. Since the water table elevations can change due to varying amounts of rain and snow and pumping by water suppliers these wetlands can be affected; in wet years they may enlarge and discharge more water while in droughts wetlands can largely dry up which happened on Long Island in the 1960’s.

It is clear, given the isolated nature of our water supply — our freshwater bubble surrounded by hostile salt water — that we are captains of our own fate. Our groundwater supply is the only source of water to meet all of our collective needs and wants. There are no magical underground freshwater connections to Connecticut, mainland New York, or New Jersey. We are not tied into, nor is it likely we will ever be able to tap into, New York City’s water supply, provided by the Delaware River and several upstate reservoirs. As the federal Environmental Protection Agency has declared — Long Island is a “sole source aquifer.” To paraphrase the late Senator Daniel Patrick Moyhihan: “Long Islanders all drink from the same well.” Indeed we do.

The next article will detail the quality and quantity problems facing our groundwater supply.

To borrow from the Pink song in the movie Happy Feet, the Pew Trusts for Marine Conservation recently delivered “something good” to Stony Brook University’s Heather Lynch. 

Endowed chair for ecology and evolution at Stony Brook University’s Institute for Advanced Computational Science, Lynch was selected as one of six Pew Fellows in Marine Conservation.

Lynch, who uses a host of tools including physics and satellite imagery to study penguin populations in Antarctica and associated island groups including in South Georgia and the South Sandwich Islands, is one of six international recipients of the 2022 fellowship, which includes $150,000 over three years, and is a mid-career prize.

Lynch plans to use the funds to chronicle species health in the macaroni and king penguin and forecast risks to Antarctica’s penguin populations.

Lynch’s work is “really important,” said Claire Christian, Executive Director of the Antarctic and Southern Ocean Coalition (ASOC), who nominated Lynch for the fellowship. Lynch provides the kind of information “we need to make effective decisions about protecting Antarctica.”

Christian, who has known Lynch for about five years, said Lynch’s consistent commitment helps “provide a broader picture of what’s happening down there over a longer time frame.”

Christian is particularly pleased that Lynch’s work in the Antarctic brings necessary attention to the region, even though “it’s far away at the end of the world,” she said. “People understand that [the Antarctic] is worth investing time and resources into studying.”

The Pew Fellows Program in Marine Conservation provides recipients with an opportunity to interact with other winners and alumni. This year, the Pew Trust received over 50 nominees.

Past honorees at Stony Brook University include Endowed Professor of Ocean Conservation Sciences at the School of Marine and Atmospheric Science Ellen Pikitch and Endowed Research Chair for Nature and Humanity Carl Safina.

Jane Lubchenco, who won a Pew Fellowship in marine conservation in the 1992, was the first woman to lead the National Oceanographic and Atmospheric Administration and is the current Deputy Director for Climate and Environment in the White House.

Rebecca Goldburg, Director of Environmental Sciences at the Pew Charitable Trusts, appreciates the mixture of high-level research Lynch produces and the application of her discoveries to conservation and added that Lynch has “outstanding scientific achievement that is well-integrated into decision making.”

Climate change

While researchers haven’t broadly chronicled the movement of macaroni penguins into the Antarctic, Lynch anticipates that climate change would draw them into the Antarctic.

“My hope is that a focus on macaroni penguin census data will illuminate their trends,” she explained in an email.

King penguins, meanwhile, have recently arrived in the Antarctic. The presence of king penguins would represent a turning point for Lynch, as they would suggest that the Antarctic is starting to show ecological similarities with the sub-Antarctic.

King penguins have attempted to breed on Elephant Island, which is about 800 miles from their typical habitat in South Georgia. While this species of penguin has traveled this distance in prior years, their decision to settle and try to raise chicks, which they haven’t successfully done, is “new and ecologically interesting,” Lynch explained.

Lynch suggested such a geographic expansion is rare because these birds are long-lived and an established pair will breed in the same location for years. Even in young individuals traveling to new territories, the rate of range shift is slow and hard to track.

“The movement of king penguins into Antarctica is exactly what would have been predicted and so it is an exciting (if, from a climate perspective, disturbing) time to be watching this all unfold,” she said.

King penguins can form large colonies, which could, over the course of a longer period of time, create competition for space with chinstraps. Lynch suggested that the region could be in the early days of an ecologically important event.

Where’s Waldo?

As for macaroni penguins, whose stories about how they got their name include one involving a sailor slang for men who dressed in bright colors, they have frequently been the “Where’s Waldo?” of what Lynch does, she said, as she encounters them by chance in a colony of another species.

She is pulling together several decades of offhand notes about her findings on macaronis to track them systematically. She believes collecting information about populations of macaroni and king penguins in Antarctica is going to be informative.

In analyzing penguin populations across species, Lynch plans to take the kind of approach portfolio managers apply when they consider where to focus their attention.

A mutual fund manager with a large percentage of the value of the fund linked to changes in the stock price of Apple would likely track the earnings of the company and its share price more closely than stocks in which she has smaller holdings or whose values don’t fluctuate much.

For penguins, Lynch suggested that scientists and conservationists may “need to understand those colonies, and there may not be that many, that contain a large percentage of the world’s population,” she said.

For a long time, researchers have focused on colonies that were easier to study because they were small and close by. “I don’t think we can justify that approach anymore,” Lynch said.

Picking penguin spots

Goldburg appreciates Lynch’s framework for penguin conservation.

Lynch will address the “key penguin colonies,” some of which are contributing disproportionately to the risk of penguin declines, Goldburg said. This approach will enable conservationists to monitor important sites because they “can’t do everything.” 

Understanding penguin populations goes beyond a simple rule that more of any population is necessarily better. Major increases or decreases should be cause for concern because they reflect shifts in the functioning of the ecosystem, she explained.

Christian is confident the work Lynch does will provide policy makers with key information.

“Her work is really important and it deserves to have a lot of visibility and funding,” Christian said. “Without understanding what’s happening to species that are living down there, we can’t” design effective strategies to protect them and their ecosystems.

Lynch provides the kind of information necessary to “make effective decisions about protecting Antarctica,” Christian added.

On March 16, environmental advocates met with public officials at the Northport Yacht Club to announce the addition of four rain gardens along Northport Harbor.

Adrienne Esposito, executive director of Citizens Campaign for the Environment, said her organization has partnered with the Village of Northport and the yacht club to address water pollution. According to her, rain gardens are a cost-effective and simple way to protect the harbor.

“In short, a rain garden is a nature-based solution to man-made pollution,” she said. “Stormwater runoff carries with it pesticides and fertilizers and other pollution and contaminants into our surface waters across Long Island. This rain garden is very important because it will be removing thousands of gallons of rain before it goes into the harbor.”

Nelson Pope Voorhis, a Melville-based engineering firm, is making this vision a reality. According to Rusty Schmidt, landscape ecologist at Nelson Pope, the proposed rain gardens will act as a filtration system, flushing out debris and other sources of pollution, to discharge stormwater safely into the harbor.

“A rain garden is a shallow bowl that we put into the landscape and that we direct water to on purpose,” Schmidt said. “In this case, the water is going to be coming from Bluff Point Road, and as the water comes down the street it will go into these gardens first. That water will soak into the ground in one day or less — in this case it will probably soak in in a few hours because the soils are sandy — and that water will be cleansed and cleaned and get to a drinkable quality.” He added, “It’s still going out to Northport Harbor, but through the soil and without all the garbage.”

We once had a thriving, billion-dollar shellfish industry here on the Island, and this is an important measure to bring back those types of species.

According to a study conducted by the U.S. Department of Agriculture, Northport Harbor and Northport Bay are both designated as priority waterbodies. Schmidt said that the proposed rain gardens would capture roughly 15,000 gallons of rainwater during a storm event, removing several harmful contaminants from the runoff before it reaches the harbor.

“Nitrogen is the number one pollutant to our bay, and we are eliminating a large volume of nitrogen from these rain gardens,” Schmidt said. “Nitrogen is the main component of growing the algal blooms, the red tides and the brown tides that are causing low oxygen and other problems in the harbor.”

The project is made possible by grants from the Long Island Sound Study and the National Fish and Wildlife Foundation’s Long Island Sound Futures Fund. Policymakers suggest this project will help to revitalize Northport’s decimated aquatic ecosystems.

“We once had a thriving, billion-dollar shellfish industry here on the Island, and this is an important measure to bring back those types of species,” said state Assemblyman Keith Brown (R-Northport). “I ran on a platform of cleaning up the Long Island Sound, the bays and the estuaries. The quality of them is a really important issue of mine, being from Northport.”

Ian Milligan, deputy village mayor and commissioner of Docks & Waterways, Police and Personnel, confirmed that the rain gardens near the yacht club will be the first of several planned to be installed throughout the village.

“We have a huge runoff water problem here in Northport and it all ends up in the harbor,” Milligan said. “This is the first rain garden that we’re doing in Northport and I’m also happy to say that the village, through other grants and other programs, has three more that are going to be coming out this year.”

According to Esposito, these projects will lead to a cleaner, safer Northport Harbor.

“The bottom line is that this rain garden really will be a simple solution to rainwater pollution,” she said. “We will be using native plantings and taking an area right now that floods and reimagining that area as a beautiful garden that will be absorbing the rain and filtering those pollutants, thereby protecting the harbor.”

Esposito added that construction of the proposed rain gardens near Northport Yacht Club will begin this spring.

While she hasn’t resolved the debate about two approaches to a type of heart surgery, Laurie Shroyer, Professor and Vice Chair for Research in the Department of Surgery at Stony Brook University’s Renaissance School of Medicine, has contributed considerable information over a long period of time.

In a recent study released in JAMA Surgery, Shroyer, who is the principal investigator and co-PIs Fred Grover and Brack Hattler of the Rocky Mountain Regional Affairs Medical Center, revealed that coronary artery bypass grafting had similar post-surgical death rates for the veterans in their study whether the surgeon used a heart-lung machine, called “on pump,” or performed the surgery without the machine, called “off pump.”

Using long-term results from 2,203 mostly men at 18 VA Centers in the Department of Veterans Affairs Randomized On/Off Bypass (ROOBY) trial, Shroyer determined that the death rate at 10 years was 34.2 percent for off-pump, compared with 31.1 percent for on-pump.

Patients typically need bypass graft surgery when they have a narrowing of their coronary arteries, which comes from fatty material accumulating in the walls of the arteries. Doctors take a part of a healthy blood vessel from the leg, wrist or elsewhere and bypass the blockage, building a detour for the blood and enabling better circulation in the heart.

Using the “off pump” procedure means doctors operate on a heart that’s still pumping blood through the body. The “on pump” procedure uses a heart lung machine to pump blood while the heart remains still.

While the results of this study don’t end the debate over whether one procedure is superior to another, doctors welcomed the data as a well-researched and detailed analysis.

“There’s always going to be this ever-last question of whether off versus on pump bypass surgery is better,” said Dr. Henry Tannous, Chief of Cardiothoracic Surgery at the Renaissance School of Medicine at Stony Brook University. “There’s always going to be very little nuances with different patients that will make us pick one or the other.”

Dr. Tannous who has performed the majority of all bypass surgeries at Stony Brook over the last five years, said the hospital offers surgeries with and without the pump. SB has doctors who specialize in each kind of bypass in case of a change in the expected procedure.

Doctors typically get a clear sense of whether a patient might benefit from on or off pump procedures before starting surgeries. In the great majority of cases, doctors perform the surgery according to their pre-planned expectations for the use of the pump.

Rarely, they convert to the other procedure based on inter operative findings that dictate the switch, Dr. Tannous explained.

Dr. Jorge Balauger, Associate Chief of Cardiothoracic Surgery and Director of Advanced Coronary Surgery, has performed 4,000 CABG procedures, including about 1,000 without the heart lung machine, or “off pump.”

In his considerable experience, he suggested that an 80-year old, who has renal or liver dysfunction and/or arteries in his or her neck that are partially blocked or had another type of comorbidity, such as something in the bone marrow, would not tolerate a heart lung machine well. A person with cirrhosis also would likely be better served with an off pump operation.

“Avoiding the heart lung machine on the older, sick patients is beneficial,” Dr. Balauger said, adding that he looks at the CABG procedure as being akin to a “tailor made suit” that has to fit the patient specifically.

In cases where patients need a second bypass procedure, Dr. Balauger also recommends off pump efforts because a second operation on pump is “way more complex” and requires “dissection of all the scar tissue around the heart, which makes it not only time consuming, but also risky.”

Dr. Tannous appreciates the perspective Shroyer brings to the discussion. “Sometimes, it’s an asset to have a researcher and statistician with a very scientifically oriented mind lead the study,” he said, adding that when surgeons meet with patients, they will discuss the use of the pump.

Dr. Baulager described the trial conducted by Shroyer as having an “excellent design” from a scientific standpoint.

He believed, however, that the study didn’t include surgeons who had sufficient expertise in off pump procedures. Dr. Baulager thought more experienced surgeons likely ensured better outcomes for off pump procedures.

One aspect of the study that was “refreshing” to Shroyer was how durable the surgical procedure is, with about 70 percent of patients who received this procedure, both on and off pump, still experiencing improvements in their pre-surgical chest pain symptoms after 10 years.

“We never expected the high proportion of patients would do so well longer term in terms of freedom from events, and in terms of symptoms,” she said. “The fact that the symptoms weren’t different between on and off pump is good news.”

After this type of study, Shroyer will work with several other trials to identify if certain sub-groups of high risk patients may have benefits from an off pump procedure.

To be sure, Shroyer cautioned that these results couldn’t be extrapolated to the general population, especially to women, as almost all of those the study followed were men.“Veterans are a unique population,” she said. “Many received cigarettes as part of their rations, and hypertension is quite high. They are a different population in terms of their [health care] complexities and their [underlying] illnesses.”

While the 10 year outcomes were similar, Shroyer found a shorter revascularization-free survival period among off pump patients. 

Dr. Tannous said this kind of study would generate considerable interest among cardiac surgeons.

“Everything [Shroyer] has written about bypass surgery from the ROOBY trials will catch any cardiac surgeon’s attention nationwide,” he said. “This paper is not any different. It has the extra long-term follow up that makes it more relevant.”

At the March 3 Town Board meeting, Councilwoman Jane Bonner recognized a group of Rocky Point High School Technology students who created a prosthetic hand for Anun Suastika, a six-year-old Indonesian boy who was born with no fingers on his right hand. Anan’s father made a plea on a website called E-name for someone to help make a prosthetic hand for his boy. 

Mr. Schumacher, passionate about teaching students the technology skills that they can use in many career fields, happened upon e-NABLE, an organization with volunteer members who use open-source technology and 3-D printers to provide free prosthetic hands for children and adults. He thought it would be a great way to blend technology and humanity into a project for his students and guided them as they built the prosthetic hand using the school’s 3-D printer. 

The students worked during free periods and after school to design and assemble the 3-D parts into a Phoenix V-3 prosthetic hand. As traditional prosthetics normally cost thousands of dollars and need to be replaced as children grow, the production of a printed Phoenix V-3 prosthetic hand is much more inexpensive because of its design: It simply relies on a person’s functional wrist and uses the palm to push against the device so the fingers close when the wrist is bent.

“It is not every day that high school students can make such a big impact on a person’s life, but these students did just that. I thank Mr. Schumacher and his Technology class for taking on the challenge to improve Anun’s quality of life,” said Councilwoman Jane Bonner. 

“We are grateful to Mr. Schumacher and these students for this project that will have a profound effect on a boy’s life,” Rocky Point School District Superintendent of Schools Dr. Scott O’Brien said. “The enthusiasm and passion shown by this committed group is inspiring to others in our school district, learning that in our classrooms they too can make a difference in the global community.
