UGA Skidaway Institute scientists participate in 2020 Ocean Sciences Meeting

The UGA Skidaway Institute of Oceanography was well represented at the 2020 Ocean Sciences Meeting in San Diego in February. The Ocean Sciences Meeting is the flagship conference for the ocean sciences and the larger ocean-connected community. The Ocean Sciences Meeting was co-sponsored by American Geophysical Union, the Association for the Sciences of Limnology and Oceanography, and The Oceanography Society.

Professor Marc Frischer said he was impressed by the efforts of the ocean science community to evolve the climate change dialog and narrative.

“As Margaret Leinen said in her closing plenary address, we started at ‘the ocean is too big to be affected’, to ‘the ocean is too big to fix,’ to where we are today, ‘the ocean is too important not to fix,’” Frischer said. “The call is for the ocean science community to become engaged in searching for solutions, and we have a lot to offer.” Leinen is the director of Scripps Institution of Oceanography.

Frischer presented some of his most recent work investigating the ecological significance of doliolids in continental shelf systems. In addition to that presentation, a student from Savannah State University, who worked in Frischer’s lab last summer, presented the results of work she conducted. Frischer mentored Ashly Rivera as part of Savannah State’s Research Experiences for Undergraduates program. At the end of each summer the REU students present their research and vote on who they think did the best job. The winner is awarded an all-expense paid trip to a science meeting of their choice. This past summer Rivera won that honor and chose to attend the Ocean Sciences Meeting. Ashly presented a poster titled “The Re-Acquisition of Shrimp Black Gill Infections by Penaeid Shrimp; Oceanic or Estuarine Sources?”

Assistant professor Catherine Edwards co-chaired a session on western boundary current-shelf interaction. The session was inspired by her and fellow Skidaway Institute scientist Dana Savidge’s ongoing research into ocean currents around Cape Hatteras, “Processes driving Exchange at Cape Hatteras,” also known as PEACH. Edwards also presented a poster on the vertical structure of Hatteras and Gulf Stream fronts as part of a large group of PEACH researchers. She was a co-author on four other posters and two talks, including posters by Savidge and UGA Skidaway Institute research technician Ben Hefner. Hefner’s poster explored data from the multiple nested high frequency radars at PEACH, using different combinations of radials to get realistic data over Diamond Shoals at Cape Hatteras.

“With their high wave energy and treacherous conditions for sampling, the shallow waters of shoals are a very difficult places to get good data,” Edwards said.

Edwards’ poster looked at the vertical layering at the boundaries of Mid Atlantic Bight, South Atlantic Bight, and Gulf Stream water. “You see interleaving of up to five layers in just 20-30 meters water depth, which is important for exchange of heat and salt between the deep and shallow ocean,” Edwards said.

Assistant professor Adam Greer was the lead author and presented a poster titled “High-resolution sampling of a broad marine life size spectrum to examine shelf biophysical coupling.” He was also a co-author for three other posters and one oral presentation.

Associate professor Clifton Buck presented a poster titled “Aerosol trace element concentrations and fractional solubility in the North Pacific Ocean: US GEOTRACES GP-15 Pacific Meridional Transect.” He was also the co-author on an additional poster and two talks.

Professor Jay Brandes lead an oral presentation on “Variability of microplastics in estuarine systems and consequences for organism studies.”

“Studies of microplastic pollution have really taken off in the last couple of years,” Brandes said. “There were two solid days of talks and posters on the subject from around the world, from basic studies to community cleanup efforts. This level of interest would have been unheard of in past meetings.”

He was also a co-author for three poster presentations. Graduate student Kun Ma was the lead author on one of those poster presentations, “Constraining photochemical production rates of dissolved inorganic carbon in the open ocean using the moderate dissolved inorganic carbon (DI13C) isotope enrichment (MoDIE) method.”

Gray’s Reef explores sounds of the ocean with virtual learning

NOAA Gray’s Reef National Marine Sanctuary is working to continue to provide virtual learning opportunities while working from home. An ongoing collaboration between Exploring by the Seat of Your Pants and the Office of National Marine Sanctuaries hosted an hour-long webinar, Exploring the Sounds of Gray’s Reef, with Gray’s Reef scientists.

Marine scientists map fish habitats

by Alan Flurry

Beyond the barrier islands of coastal Georgia, the continental shelf extends gradually eastward for almost 80 miles to the Gulf Stream. This broad, sandy shelf largely does not provide the firm foundation needed for the development of reef communities to support recreational and commercial fish species including grouper, snapper, black sea bass and amberjack.

“Natural and artificial reef habitats are important to Georgia fisheries because they provide hard, permanent structure on the Georgia shelf, which is dominantly a vast underwater desert of shifting sands,” said Clark Alexander, professor and director of the University of Georgia Skidaway Institute of Oceanography. “The Georgia Department of Natural Resources has invested significantly over the past several years in developing the capacity to map these areas to enhance the management of these reef communities.“

To increase the availability of high-quality hard bottom areas off Georgia, the DNR began an artificial reef-building program in 1971 to deploy materials at various locations across the continental shelf, from 2 to 30 miles offshore. Reef materials include concrete slabs and culverts from road, bridge and building demolition, subway cars, ships, barges, and U.S. Army tanks. Because some of these reefs are far offshore and DNR resources are limited, the status of some of that material has not been examined for decades.

For the past five years, Alexander has been leading an effort to improve understanding of marine, coastal and estuarine habitats and functions using high-resolution sonar to map state water bottoms, with funding from the DNR Coastal Incentive Grant program. Alexander’s team has amassed critical depth and habitat information for five of Georgia’s sounds (Wassaw, Ossabaw, St. Catherine’s, Doboy and Sapelo), revealing deeply scoured areas where underwater cliffs have formed to create hard substrate where complex ecosystems and biological communities have developed.

“These inshore, hardbottom habitats should enhance biodiversity in the areas near these structures and enhance ecosystems supporting both commercial and recreational species across the continental shelf,” Alexander said.

Alexander is currently leading a new, three-year project mapping important fish habitats in state waters — the newly discovered estuarine habitats, and artificial reef structures within 10 nautical miles of shore – those areas most accessible to recreational anglers, boaters and divers. In addition, his research group is mapping previously unmapped portions of the sounds and tidal rivers deeper than 15 meters to discover the extent of these newly identified estuarine hardbottom habitats.

Skidaway Institute researchers will work with DNR to update the online “Boater’s Guide to Artificial Reefs” with accurate locations and imagery of deployed materials for these reefs. These new, more accurate artificial reef surveys will also document recent changes in the locations and integrity of placed materials and verify the low-tide water depths over all features in the artificial reefs to enhance navigational safety.

New high-tech microscope to bolster UGA Skidaway Institute’s microplastics research

A new, high-tech microscope is giving scientists at the University of Georgia Skidaway Institute of Oceanography a tool to study the tiniest particles and organisms in our environment in a whole new light. The Horiba Jobin Yvon XplorRA Plus Confocal Raman microscope uses lasers, rather than conventional light or a stream of electrons, to examine objects measuring smaller than a millionth of a meter or .04 thousandths of an inch.

“The way a Raman microscope works is fundamentally different from how conventional microscopes, such as those found in the classroom, operate,” UGA Skidaway Institute scientist Jay Brandes said. “With this instrument, a high energy laser beam is directed at the sample, and the instrument measures the light scattered back from it.”

What distinguishes it even more from traditional microscopes is a phenomenon called the Raman effect. This was discovered in the 1930s by Indian physicist Chandrasekhara Venkata Raman. With the Raman microscope, some of the scattered light comes from interactions with the molecules in the sample, and these interactions leave a spectral “fingerprint” that can be isolated from the laser light and measured. Those “fingerprints” can tell scientists what the material is made of, whether it is natural organics like bacteria or detritus, inorganic minerals or plastics.

“Because it uses a high tech, automated microscope to perform these measurements, maps of sample composition and even three-dimensional maps are possible,” Brandes said.

OLYMPUS DIGITAL CAMERA

The Raman microscope uses a laser to illuminate and analyze an object.

One immediate use for this instrument will be to study microplastic pollution in Georgia’s coastal environment. Brandes and a group of educators, students and volunteers, have been researching the microplastic pollution issue in coastal Georgia for several years. He says that locating and identifying microplastics in the environment or in an organism is difficult because of their tiny size.

“It’s not like it is a water bottle where you can look it and say ‘That’s plastic,’” Brandes said. “We see all kinds of microscopic particles, and, because they are so small and not always distinctively colored or shaped, it is difficult to distinguish microplastics from other substances.

“With this microscope, we will be able to look at a fiber and tell whether it is made of polyester, nylon, kevlar or whatever.”

Brandes and his team have been looking at the microplastics problem from several angles. They have taken hundreds of water samples along the Georgia coast, filtered the samples and analyzed the captured particles and fibers. The researchers also examine marine organisms, like fish and oysters, to see what organisms are consuming the microplastics and to what extent.

The instrument will allow sub-micron analysis of complex samples from a wide variety of other projects. It will be available to UGA Skidaway Institute scientists as well as other scientists from throughout the Southeast. In addition to benefitting researchers, the Raman microscope will enhance educational programs conducted at Skidaway Institute and the through the UGA Department of Marine Sciences. Once a set of standard methods and protocols have been established, it will also be available to support scientific research from institutions and organizations from around the Southeast.

The instrument was purchased with a $207,000 grant from the National Science Foundation.

Skidaway Institute of Oceanography: 50 years of marine research and education

The Skidaway Institute of Oceanography was born in 1968, but the story of the institute began several years earlier with a dream of some local and state leaders to give Georgia a foothold in the burgeoning field of oceanography. In 1964, the Georgia General Assembly formed the Georgia Science Technology Commission with an Oceanographic Task Force. Two years later this task force proposed that an oceanographic research laboratory be established on the coast. That same year, the U.S. Environmental Science Services Agency decided to establish an east coast facility. State and local leaders wanted to attract the federal facility to Georgia. To that end, in 1967 the General Assembly created the Ocean Sciences Center of the Atlantic Commission (O.S.C.A).

During this same time period, two property owners on the island offered to donate land to provide a home for the facility. Robert and Dorothy Roebling, and their family had lived on the island since the mid-1930s and operated a cattle breeding facility they called Modena Plantation.

Skidaway Institute’s current main campus is on the former Modena Plantation. Much of the remainder of the island was owned by the Union Camp corporation, which had previously used the property to grow pine trees for wood pulp to supply their paper plant in Garden City. Union Camp donated several hundred acres, which now includes Skidaway Institute’s Priests Landing dock on the Wilmington River. Union Camp also donated the land to accommodate Skidaway Island State Park.

In the end, Georgia did not win the prize for the federal facility. It was eventually established in Miami, Fla., but the idea of an oceanographic research institution on Skidaway Island was carried forward. Skidaway Institute of Oceanography was established as part of O.S.C.A. in 1968. In 1972, Governor Jimmy Carter dissolved O.S.C.A. Skidaway Institute was then assigned to the Board of Regents as an autonomous unit of the University System of Georgia (USG.)

Skidaway Institute officially opened on July 1, 1968. The former dean of Georgia Tech’s College of Engineering, Thomas Jackson, was the first director. He hired Herb Windom as the first faculty scientist. Windom had just completed his Ph.D. at Scripps Institution of Oceanography, University of California at San Diego. Soon others followed, including Howard Yen, who was finishing up a doctorate in mechanical engineering from Georgia Tech, and Jim Andrews, who was completing his doctoral work in animal nutrition from UGA.

The early support staff was very small. Jackson brought Lee Knight with him from Georgia Tech to be assistant director. Richard Buchner handled the business office, and Bonnie Zeigler was hired as a bookkeeper and secretary.

In those first days, Skidaway Institute relied heavily on the infrastructure inherited from the Roeblings, including a sophisticated firefighting system, farm buildings and dwellings, and a machine shop with equipment still in use 50 years later.

The Roebling House today

Initially, the director and all other staff had offices in the Roeblings’ two-story schoolhouse/gymnasium now called the Roebling House.

Work began fairly quickly on the first modern office and laboratory building, later named the Dorothy R. Roebling Laboratory Building. That building was completed in 1970.

In late 1969, Skidaway Institute received a new director who would play a dominant role in shaping the course of the institute over the next 23 years. David Menzel had wide-ranging experience as a marine scientist and took the reins of Skidaway Institute after a six-year tenure at Woods Hole Oceanographic Institution. He brought an instant visibility to Skidaway Institute with his research reputation in oceanography, and his national and international connections. Soon after his arrival at Skidaway, he started hiring several young scientists from various oceanographic graduate schools. Whether a biologist, chemist or physicist, scientists were expected to approach questions in a multidisciplinary fashion and in cooperation with others, so they looked at an issue across all the disciplines. His aim was to establish an oceanographic research group capable of addressing interdisciplinary research topics, particularly those focused on coastal oceanographic processes. Through Menzel’s efforts, the Skidaway Institute of Oceanography became one of the true pioneers of interdisciplinary coastal oceanography.

Because of his stature and connections, and the quality of the faculty he hired, Menzel was able to integrate the faculty into national and international research programs, workshops and meetings. This allowed them to network and make connections with colleagues, which often led to research collaborations that lasted decades.

Skidaway Institute research has covered the world, including sites as distant as Antarctica.

During the 1970s, much of Skidaway Institute’s research was focused on understanding biogeochemical processes and their relationship to circulation on the continental shelf, a true interdisciplinary endeavor. This has remained an underlying theme of Skidaway Institute’s research to the present day. Early research benefited from large block grants from the Atomic Energy Commission (AEC), later the Department of Energy (DOE). The AEC/DOE was interested in knowing the potential impacts of all things related to energy production and exploration.

The National Science Foundation declared the International Decade of the Ocean from 1971 to 1980. Skidaway Institute and Menzel took the lead in one major international project, the Controlled Ecosystem Pollution Experiment (CEPEX), the results of which spun off a second program — Vertical Transport and Exchange (VERTEX). These two projects provided funds that supported Skidaway Institute scientists for several years. CEPEX studied the responses of pelagic marine food chains to low and chronic levels of various contaminants. It originated with concerns about the potential impact of fossil fuel exploration and energy production, along with nuclear power production, on the marine environment. VERTEX’s goal was to determine just how much carbon in the form of phytoplankton detritus sank to the sea floor over a given period of time, aimed at a better understanding of the global carbon cycle.

In 1993, Menzel retired. Skidaway Institute’s first faculty scientist, Herb Windom, moved up to the director’s office. He began a campaign to significantly upgrade Skidaway Institute’s research fleet. The former fishing trawler, the Research Vessel Blue Fin, had limited capability and was aging. Eventually, the institute ordered the construction of the 92-foot, 300-ton R/V Savannah, which was built in Maine and arrived at Skidaway Institute in September 2001.

The R/V Savannah is part of the University-National Oceanographic Laboratory System (UNOLS) fleet and has been utilized by Skidaway Institute scientists as well as scientists from other institutions to conduct marine research in regions as far-flung as Chesapeake Bay, the western Gulf of Mexico and the coast of South America.

In 2001 Windom retired, and Rick Jahnke was appointed acting director until Jim Sanders, who years earlier had been a graduate student at Skidaway, took over the leadership of the institute. During Sanders’s first several years as director, the institute was challenged by funding issues as the recession of 2002-3 and the “great recession” that began in 2008 cut into the institute’s state and federal funding. The reduction in funding resulted in a reduction of support staff and the elimination of Skidaway Institute’s engineering department.

During this time, however, the institute also saw an expansion of its facilities and evolution within its faculty. The long-awaited Marine and Coastal Science Research and Instructional Center, a modern laboratory research structure, was funded through a $5 million appropriation by the Georgia General Assembly in 2006 and was completed in 2009.

Marine and Coastal Science Research and Instructional Center

It provided much needed office and laboratory space. In 2008, the General Assembly approved a $1.2 million capital appropriation to replace the institute’s aging wooden main dock with a modern concrete pier and floating docks, and to renovate two other  docks. Finally, in 2015, the state approved a $3 million appropriation to extensively renovate the Institute’s iconic, circular cattle barn (a legacy of the Roebling era) into a modern space designed to provide meeting areas, teaching spaces and exhibits for the interested public—in essence, a new “front door” for Skidaway Institute.

The 2000s also saw a transition of the Skidaway Institute faculty. In addition to Windom, a number of faculty scientists who had long been the core of the institute’s research retired, including Dick Lee, Gustav Paffenhöfer, Stuart Wakeham, Rick Jahnke and Jack Blanton. (Windom, Lee and Paffenhöfer continue to be active at the institute in an emeritus status.) These retirements, along with the death of Peter Verity, created space for an influx of new and younger researchers. During Sanders’ tenure as director, 10 new members joined the Skidaway Institute faculty. Five of those new hires were women.

In 2012, after nearly 40 years as an autonomous unit of the USG, Chancellor Hank Huckaby directed that Skidaway Institute be merged into the University of Georgia. That merger became official on July 1, 2013. The director of Skidaway Institute now reports to the university’s provost’s office. Currently the faculty are all part of the Department of Marine Sciences. The merger created a fresh set of challenges, from combining accounting systems to differences in culture and mission. The educational component of Skidaway Institute’s mission grew with the acquisition. Skidaway faculty have UGA graduate students working in their labs each year, and planning is underway to provide other unique learning experiences for graduate and undergraduate students.

In 2015, Sanders announced he would be stepping down as director in 2016. Long-time faculty member Clark Alexander was appointed interim director, and in 2017, that appointment was made permanent.

Since 1968, Skidaway Institute and its scientists have shown leadership outside of academic settings as well, providing valuable guidance to state and regional planners, resource managers and industrial stakeholders. Skidaway Institute scientists have served on national, regional, state and local advisory boards for organizations such as the EPA, National Science Foundation, NOAA-Sea Grant, NOAA-National Marine Sanctuaries, Governors South Atlantic Alliance, Georgia Coastal Management Program and the Chatham County Planning Commission.

After 50 years, nearly all the faces have changed. The technology is vastly different. The challenges are different too. Yet the mission of Skidaway Institute remains the same, to create and communicate a deeper understanding of our world through leading-edge research in the marine and environmental sciences and by training tomorrow’s scientists.

Former UGA Skidaway Institute director Jim Sanders retires

Former UGA Skidaway Institute executive director Jim Sanders retired last summer. Sanders led the institution from 2001 until 2016, when he stepped back from his executive directorship, but remained active in a faculty post. During his 15 years as director or executive director, Sanders guided Skidaway Institute through two recessions and the 2013 merger with the University of Georgia.

Sanders earned his bachelor’s degree in zoology from Duke University and followed it up with a master’s degree and doctorate in marine sciences from the University of North Carolina – Chapel Hill. His first exposure to Skidaway Institute came as a graduate student with Herb Windom in the 1970s.

Prior to his arrival in Savannah in 2001, Sanders was on the faculty and served as director of the Academy of Natural Sciences’ Estuarine Research Center in Maryland. He then was chairman of the Department of Ocean, Earth and Atmospheric Sciences at Old Dominion University in Virginia.

Sanders is known for his interests within the area of nutrient and trace element biogeochemistry, especially how trace elements are transported through coastal zones, transformed by chemical and biological reactions during transport, and how they influence growth and species composition of autotrophic organisms.

Sanders has been very active as a consultant to federal and state science agencies, and industrial groups in the U.S. and Europe. He is a member of numerous scientific societies, was president of the National Association of Marine Laboratories, and was a trustee and officer of the Consortium for Ocean Leadership. He is the author of over 75 scientific publications.

Shortly after taking the helm at Skidaway Institute, the nation was hit with an economic downturn sparked by the 9/11 terrorist attacks, and maintaining adequate funding for research and operations was a challenge.

“The most effective way to deal with it was to hire innovative and interdisciplinary faculty members who would come up with important research questions and then find funding to pursue those avenues,” Sanders said.

Looking back, Sanders said he has always been amazed at the extent to which Skidaway Institute fosters an interactive, collegial work experience.

“I have been at a number of other institutions, large and small, many with a similar focus on oceanography, but I have never felt the interconnections that Skidaway has offered, both to me and other staff, over the past 42 years,” Sanders said.

As Sanders looks back over his time at Skidaway, he is most proud for what he, the faculty and staff have done together.

“In the end, I measure my success through my colleagues and our interactions,” he said. “Really, my career has not been defined by the grants written, or the publications, or even the research that I have performed, but that I was in a position to help others achieve their goals, and perhaps even reach a bit higher in some cases.”

Sanders remains at the institute as a professor emeritus.

Ohnemus joins UGA Skidaway Institute faculty

Chemical oceanographer Daniel Ohnemus has joined the faculty of UGA Skidaway Institute of Oceanography and the UGA Department of Marine Sciences as an assistant professor.

Ohnemus received his bachelor’s degree from Williams College and his Ph.D. in chemical oceanography from the Massachusetts Institute of Technology and Woods Hole Oceanographic Institution Joint Program. He joined UGA Skidaway Institute following a postdoctoral appointment at Bigelow Laboratory for Ocean Sciences in East Boothbay, Maine.

Ohnemus’ research focuses on marine particles—the mixture of living organisms and non-living chemicals that transport and transform material within the oceans.

“All living organisms need small ‘trace’ amounts of elements like iron and copper to live,” Ohnemus said. “Unlike on land where plants can get these elements from soil, algae in the oceans have to get them from much rarer things like dust, other cells or seawater itself. The limited availability of these elements is an important control on many marine ecosystems.”

The son of a lobsterman and an elementary school educator, Ohnemus grew up on Cape Cod and became fascinated with the ocean at a young age. In fourth grade, his class visited Woods Hole to take part in a satellite video call with marine scientists off the Galapagos Islands. Seeing underwater robots explore a coral reef got Ohnemus hooked on marine science.

At Williams College, he pursued a double major in biology and chemistry. After graduation, he returned to Woods Hole, first as a research technician and later as a graduate student. After earning his Ph.D., he completed a postdoctoral appointment at the Bigelow Laboratory for Ocean Sciences, continuing to concentrate on marine particles and trace elements.

The Roebling barn in perspective

by Debbie Jahnke

Editor’s notes: Debbie and Rick Jahnke were longtime members of the Skidaway Institute family. Rick was a faculty scientist and, for several months, interim director of the institute. Debbie was his research coordinator. They both retired in 2008 and moved to Port Townsend, Washington.

 In March of this year, the Georgia General Assembly approved a $3 million bond issue to renovate and repurpose the old Roebling cattle show barn at UGA Skidaway Institute into usable laboratory and meeting space.

In 1986, Rick Jahnke interviewed for a faculty position at Skidaway Institute of Oceanography. At the time, he was a research scientist at Scripps Institution of Oceanography. Rick returned home to San Diego with the impression that he wouldn’t be hired because Stuart Wakeham had also interviewed for the position and would undoubtedly be selected. Instead, Skidaway Institute came up with the funds for two positions and hired both Rick and Stuart.

Rick’s start-up requests to Skidaway Institute were modest: a germanium detector and a desktop computer. He also requested lab and office space in the Roebling building and a staging lab in the barn for maintenance, repair and modification of his various seagoing autonomous vehicles. The barn was nearly perfect for that purpose, with plenty of storage space and a central open area that allowed loading and offloading of equipment with a hand-winched pulley system.OLYMPUS DIGITAL CAMERA

Rick didn’t need any extra space for me and, instead, split his office with a wall so there was a spot just big enough for my desk and a “labradog” named Daisy. I was the analytical tech for his research and he hired an equipment tech for the seagoing operations. The barn lab operations expanded to the second floor of the barn when it became clear that anyone interested in measuring natural levels of C-14 wasn’t going to be able to do it in many existing Skidaway Institute labs. In the free-form early days of productivity measurements, enough C-14 made it into the ambient spaces of many Skidaway Institute labs that C-14 dating indicated that our labs existed about 50,000 years in the future. The levels of so-called contamination were in no way concerning for health or safety, but they made natural abundance measurements impossible without a “clean” space for sample storage. The bright yellow room with the pink and green interior and cold room on the second floor of the barn were the result.

From those barn labs, autonomous vehicles were staged, packed and deployed for oceanographic research off western Africa, Peru, Panama, New Guinea, deep shelves off Cape Hatteras, California, Oregon and other locations, as well as the Georgia shelf. Samples were returned and stored in the yellow lab upstairs.

The barn provided another opportunity for me when I was drafted in a weak moment to try to improve what was quite dismal visitor housing at Skidaway Institute in the 1980s. The first housing we made habitable was the barn apartment. As we worked through the process of getting three NSF grants for housing, we also were able to set up a small laundry room in the barn so that volunteers could keep clean linens in the housing we did have. The first successful grant built the quadraplex (Menzel, Zeigler, Carpenter and Knight apartments). The second grant rehabilitated the housing that existed since the plantation days (the barn apartment, now renamed Baggett, Rice House, Thomas and Martin apartments). The third grant built the Commons. I spent many hours in that barn laundry room while most of my weekends and holidays were spent cleaning housing units before the institute finally figured out how to pay someone to do that as a real job.

Rick and I retired in 2008 and headed west with our five cats. All I know of the modern Skidaway Institute is what I read on the website and Facebook pages and occasional emails from friends still there. Skidaway was wonderful to us and the barn was a big part of the ease with which our research was facilitated. It was with considerable pleasure that we learned of the grand and useful future being planned for the good old barn.
