New weather station goes online

UGA Skidaway Institute’s new weather station became operational in early May.

The weather station includes a 30-foot-tall tower on the pier at Priests Landing. It has a Gill Instruments GMX531 Weather Station, collecting wind direction and speed, air temperature, relative humidity, atmospheric pressure, solar radiation and precipitation at five minute intervals. The station is powered by a solar panel, and data is sent by a cellular link to a website for display. This installation is part of a National Weather Service-funded effort to improve regional weather forecasts.

The available current and historic data can be accessed HERE. Select “Skidaway 1,” which is the 14th station on the list.

UGA Skidaway Institute’s Edwards granted tenure

The University of Georgia has granted tenure to UGA Skidaway Institute of Oceanography / Department of Marine Sciences scientist Catherine Edwards. Edwards was also promoted from assistant professor to associate professor, effective Aug. 1.

OLYMPUS DIGITAL CAMERAEdwards is a physical oceanographer, with broad interdisciplinary interests in marine sciences and engineering. She earned a B.S. in physics with highest honors from the University of North Carolina at Chapel Hill, and worked as an ocean modeler at the U.S. Naval Research Laboratory before earning her Ph.D. in physical oceanography from the University of North Carolina at Chapel Hill. She joined Skidaway Institute in 2010.

Edwards’ research focuses on answering fundamental questions in coastal oceanography and fisheries sciences with autonomous underwater vehicles (AUVs). Using AUVs, also called gliders, she and her team are developing novel ways to optimize their use with engineering principles and real-time data streams from models and observations.

While at UGA Skidaway Institute, Edwards has been awarded more than $2 million dollars on 12 projects totaling more than $12 million from NOAA/Navy sources, the Gulf of Mexico Research Initiative and four different programs within the National Science Foundation. As the founder of a regional glider observatory, she serves as the lead scientist in a new project that places gliders in the paths of hurricanes to better predict their intensity at landfall. Edwards is a co-primary investigator in a large $5 million observational program studying exchange between the coastal and deep ocean at Cape Hatteras. In an effort funded by NSF’s Smart and Autonomous Systems program, Edwards is also working with researchers from Georgia Tech and Gray’s Reef National Marine Sanctuary to utilize gliders and acoustic tagging to track fish migrations.

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.

Despite COVID-19 delays, UGA Skidaway Institute scientist heading home from the Arctic

After four months at sea, including two and a half months on board a German ice breaker locked in the Arctic ice cap, University of Georgia Skidaway Institute of Oceanography scientist Chris Marsay is on his way home. His return trip comes six weeks later than planned due to travel restrictions imposed by the COVID-19 crisis.

Chris Marsay, all wrapped up for working out on the ice during windy conditions.

Marsay has been on board the research vessel Polarstern as part of a major international research project to study climate change in the Arctic named Multidisciplinary drifting Observatory for the Study of Arctic Climate, or “MOSAiC.” Last fall the Polarstern sailed into the Arctic Ocean until it became locked in the ice. The plan was for the ship to drift with the ice for a year all the while serving as a headquarters for scientists to study Arctic climate change. Scientists were scheduled in shifts or “legs” to work for two to three months at a time. However, unable to exchange the science teams by either air or with another ice breaker, MOSAiC organizers decided to pull the Polarstern out of the ice pack and leave the research station for an estimated three weeks while the changeover takes place.

“My time working at the MOSAiC ice floe has come to an end, and I am currently traveling south on the Polarstern towards Svalbard where the exchange between personnel from legs three and four of the project will take place,” Marsay said. “Due to the travel restrictions in place because of COVID-19, it was not possible to carry out the exchange at the ice floe itself as originally planned.”

The replacement team is already at Svalbard aboard two other German vessels. They completed a two-week quarantine and multiple coronavirus tests before departure. The teams will exchange ship-to-ship in a fiord since Svalbard, a Norwegian archipelago, is closed to outside visitors because of COVID-19.

According to Marsay, his time at the MOSAiC ice floe has been eventful. “The ice was much more dynamic than it had been during the first months of the MOSAiC project,” he said. “Cracks and leads frequently opened up in the area around the ship, and the ice movement also formed ridges of ice blocks several feet high.”

Ice Crack 650p

A crack that opened up next to the ship in mid-March meant that some equipment had to be hurriedly moved to safety.

All of these events restricted access to some research sites, but the work continued, providing new sampling opportunities for the researchers.

This was not Marsay’s first trip to the Arctic. A 2015 research cruise took him to the North Pole, but this trip was a new experience. “It’s been unique to witness the transition from winter to spring in the central Arctic Ocean,” he said. “During our time at the floe we experienced a minimum temperature of negative 40 degrees Celsius, not accounting for wind chill, and a maximum of zero degrees Celsius. The sun did not rise until two weeks after we arrived at the floe, and has not set since late March.”

Marsay also experienced windy days with storm-force winds and whiteout conditions due to blowing snow, and days with beautiful clear skies when the sun reflecting off the snow was dazzling, he said.

Ship Blown Snow 650p

As calm conditions gradually return after a couple of days of windy conditions, Polarstern is visible through some blowing snow at ground level.

During his participation in MOSAiC, Marsay collected snow, ice cores, sea water and aerosol samples as part of our project studying the atmospheric deposition of trace elements in the central Arctic.

SkiDoo 600p

Each Monday, Marsay was part of a team that collected multiple ice cores at a site far enough away from the ship that a Ski-Doo and sledges were needed.

He also learned some new skills, including driving a Ski-Doo, and on several occasions he carried a rifle and served as a polar bear guard for colleagues.

Bear Tracks 480p

The researches had one polar bear visit (that they know of) during leg 3. These footprints within a couple of hundred yards of Polarstern.

“We on board will have been at sea for over four months by the time we get to Germany,” Marsay said. “When we started, the COVID 19 virus was not widespread outside of China.

“We have all been following the news from back home, and although we’re looking forward to getting home, everyone is expecting some initial difficulties getting used to the way that public life has changed while we’ve been away.”

UGA Skidaway campus reacts to COVID-19 crisis

Like everyone else in the country, the organizations on the UGA Skidaway Marine Science Campus have been affected by the COVID-19 pandemic.

In mid-March, UGA Skidaway Institute cut back on all on-campus activities. Most active research was put on hold and faculty and staff were directed to telecommute as possible. Scheduled research and educational cruises on board the R/V Savannah were postponed. A small team of staff members continue to work on campus to maintain facilities and systems. Monthly Evening @ Skidaway public programs are cancelled, at least through the summer.

“Although we are currently pausing our research and educational efforts, we are eager to restart those programs as soon as it is safe to do so,” Director Clark Alexander said.

UGA Marine Extension and Georgia Sea Grant shut down operations about the same time. The UGA Aquarium closed, and all educational field trips were cancelled for the remainder of the school year.

“Our biggest priorities in our response has been the health and safety of our staff and the public that we interact with regularly,” Mark Risse, director of Marine Extension and Georgia Sea Grant said. “For this reason, we made the hard decision to cancel many of our public programs and conferences this spring, as well as our summer marine science camps scheduled in June and July.”

Educators at the UGA Aquarium have transitioned several in-person public programs to virtual platforms. Registration is currently open for a series of engaging online events scheduled for June and July that focus on marine animals and coastal habitats. Learn more at gacoast.uga.edu/events.

Marine Extension and Georgia Sea Grant’s Shellfish Research Lab is supporting the aquaculture industry by providing technical assistance to shellfish growers and sharing information about COVID-related resources. A handful of extension specialists at the lab continue to keep the oyster hatchery running and are producing oyster seed for shellfish farmers on the coast.

Gray’s Reef National Marine Sanctuary remains open while its headquarters facilities on the UGA Skidaway Marine Science Campus are closed and staff is working from home. Most non-essential operations and research activities have been postponed, including the annual NOAA Ship Nancy Foster expedition, typically hosted in mid-July. The Gray’s Reef Expo on River Street has been tentatively rescheduled for November 21-22. Outreach from Gray’s Reef is focusing on digital and virtual events.

UGA Skidaway Institute scientists publish two papers on Arctic processes

The Arctic is experiencing the effects of climate change faster than anywhere on the planet, yet it is one of the least understood regions, due largely to the difficulty of making observations and collecting samples there. With the support of National Science Foundation funding, two University of Georgia Skidaway Institute of Oceanography scientists are studying the biogeochemical processes in the Arctic and recently had their research published in two peer-reviewed science journals.

Postdoctoral researcher Christopher Marsay and assistant professor Clifton Buck have been participants in the international GEOTRACES program which aims to improve the understanding of biogeochemical cycles in the ocean, focusing on important trace elements. Trace elements are present in the ocean in very low concentrations, however some of those elements are essential for marine life and can influence the functioning of ocean ecosystems while others are potentially toxic to plants and animals.

Cliff Buck works with deck equipment during a GEOTRACES cruise in the Pacific Ocean.

“The Arctic part of the GEOTRACES program is particularly important because the region is already showing significant changes as a result of climate change and is relatively poorly studied with respect to many trace elements,” Marsay said.

Marsay is the lead author on both papers, which are the result of analysis of samples he collected on a 64-day GEOTRACES cruise from Dutch Harbor, Alaska to the North Pole and back from August through October 2015.

“On this cruise, our research goals were to describe the chemistry of atmospheric deposition to the region,” Buck said. “These data will then be shared with the scientific community to help better understand biogeochemical cycling of trace elements in the Arctic Ocean.”

The first paper, published in the journal Chemical Geology, describes the concentrations of 11 trace elements in atmospheric samples that Marsay collected during the cruise by pumping large volumes of air through filters. The sources of this material could include natural material from land surfaces, smoke and soot from burning vegetation, and emissions from industrial activity.

“We compare the results to other ocean regions and speculate as to the sources of the material reaching the Arctic,” Marsay said. “An important part of the work is that we used the concentration data to estimate how much of these chemicals settle from the atmosphere to the surface of the ocean.”

In addition to Marsay and Buck, co-authors included David Kadko from Florida International University, William Landing and Brent Summers from Florida State University, and Peter Morton from the National High Magnetic Field Laboratory.

The second paper was published in the journal Marine Chemistry. In it, Marsay and his co-authors examine trace elements in Arctic melt ponds. Melt ponds are a widespread feature of the sea ice in the Arctic during the summer months. As snow melts it forms ponds on top of the ice which eventually drain into the surface ocean.

“Melt ponds are an important intermediate step in atmospheric deposition to the surface ocean that is unique to the polar regions and not very well studied,” Marsay said. “Ongoing climate change in the Arctic will change this pathway, and we want to know how that may affect distribution and biological availability of trace elements in the surface ocean.”

The paper brought together measurements of several trace elements made by different research groups involved in the GEOTRACES project. It showed that the chemistry in melt ponds is also influenced by material in sea ice and the seawater beneath the ice, which modifies the chemistry of material deposited from the atmosphere before it reaches the surface ocean.

Additional co-authors on the paper included Ana Aguilar-Islas from the University of Alaska Fairbanks, Jessica Fitzsimmons, Laramie Jensen and Nathan Lanning from Texas A&M University, Mariko Hatta from University of Hawai’i at Manoa, Seth John and Ruifeng Zhang from the University of Southern California, David Kadko from Florida International University, William Landing from Florida State University, Peter Morton from the National High Magnetic Field Laboratory, Angelica Pasqualini from Columbia University, Sara Rauschenberg and Benjamin Twining from the Bigelow Laboratory for Ocean Sciences, Robert Sherrell from Rutgers University, and Alan Shiller and Laura Whitmore from the University of Southern Mississippi.

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.

Dorothy and Robert Roebling in 1967

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.
