Thomas Hurst, Ph.D.

NOAA/NMFS Alaska Fisheries Science Center

Thomas Hurst is a Research Fisheries Biologist with the NOAA-NMFS Alaska Fisheries Science Center in the Fisheries Behavioral Ecology Program located at Oregon State University’s Hatfield Marine Science Center in Newport, OR. He earned a B.S. in Wildlife and Fisheries Biology from the University of Massachusetts in Amherst. Graduate studies (M.S. and Ph.D.) on the recruitment and ecology of overwintering Hudson River striped bass were done at Stony Brook University in New York under the direction of Dr. David Conover. As a post-doctoral researcher, Tom examined patterns of community variation in the lower Hudson River Estuary. He joined the AFSC in 2002. Tom also holds an appointment as a Courtesy Assistant Professor in the Department of Fisheries and Wildlife at Oregon State University.

Tom’s research blends field studies and laboratory experimentation to examine the ecology of early life stages of marine species and the constraints imposed on this ecology by the environment. Much of this work focuses on the pervasive influence of temperature variation on the physiology and ecology of fishes, including behavior, habitat selection, growth energetics, and larval ecology. New areas of research include the dispersal patterns of Pacific cod and the potential impacts of ocean acidification on fishes of the Bering Sea and Gulf of Alaska. His research is focused on species of commercial importance in Alaska: walleye pollock, Pacific cod, northern rock sole, and Pacific halibut.


Christopher Long, Ph.D.

NOAA/NMFS Alaska Fisheries Science Center, Kodiak Laboratory

Dr. William Christopher Long, pictured explaining the intricacies of benthic ecology to his daughter, worked in Chesapeake Bay for seven years, where he earned his doctorate in Marine Science from the Virginia Institute of Marine Science, the College of William and Mary, and completed a post-doctoral fellowship from the Smithsonian Institute. His research in the east examined the effects of hypoxia on the Chesapeake Bay ecosystem, predator prey dynamics between crabs and bivalve prey, and the importance of near-shore habitat for blue crabs. He joined the National Marine Fisheries Service in 2009 and has been working out of the Kodiak Laboratory doing research on king and Tanner crabs in Alaska. Current research includes the effects of ocean acidification on all life history stages of king and Tanner crabs, the influence of habitat on crab predator-prey dynamics, and king crab stock enhancement.


Derek Manzello, Ph.D.

NOAA Atlantic Oceanographic and Atmospheric Marine Laboratory

Derek Manzello is the lead PI of the Coral Reef Monitoring Network, Ocean Adification Program. His research explores how climate change and ocean acidification will, and, already are, affecting the construction (coral growth, calcification) and breakdown (bioerosion, dissolution) of coral reefs, as well as the associated ramifications this has for ecosystem function (e.g., biodiversity). He utilizes a unique interdisciplinary approach that incorporates aspects of biology, chemistry, and geology within an ecological framework. And also relies heavily on field research to understand how coral reefs are structured and function across real-world gradients in seawater CO2. For example, his past research has demonstrated that eastern tropical Pacific (ETP) coral reefs exist under naturally-occurring, high-COconditions that encompass the range of expected changes in seawater carbonate chemistry for the entire tropical surface ocean with a doubling and tripling of atmospheric CO2. Reef framework development and cementation, as well as resilience to El Niño warming, correlate with the regional variability in COlevels across the ETP. These results provide important insights on the future function and structure of coral reef ecosystems with anthropogenic climate change and ocean acidification.

He is currently overseeing and maintaining the NOAA: 1) Ocean Acidification Program’s Coral Reef monitoring Network, 2) in situ climate and ocean acidification requirements of the NOAA Coral Reef Conservation Program’s (CRCP) National Coral Reef Monitoring Plan, and 3) CRCP’s Atlantic Ocean Acidification Test-Bed, all three of which are within the Atlantic basin. Coincident with these efforts, he is measuring how multiple species of coral calcify, as well as how rates of bioerosion vary across natural COgradients on US coral reefs. This involves experimental work to understand how important coral reef species affect seawater carbonate chemistry and their response to high CO2. He continues to investigate these interdisciplinary themes, via combined field and experimental work, with the ultimate goal of understanding the exact inputs of thermal stress and ocean acidification, where the goods and services of coral reef ecosystems are lost, and how, through ecosystem-based management, we can buy time for these natural treasures.


Shannon Meseck, Ph.D.

NOAA/NMFS Northeast Fisheries Science Center

Shannon Meseck is a research chemist at the Northeast Fisheries Science Center.  She earned her undergraduate degree from SUNY Plattsburgh (1993) in Chemistry and Environmental Science and holds a Ph.D. in Oceanography from Old Dominion University (2002).  Her research focuses on how variations in chemical variables (e.g. carbon dioxide) in the environment influence growth of different phytoplankton species and the consequences this has on the food web.  Phytoplankton primary production is the building block of the marine food web, and variations in species composition can have dramatic effects upon grazers.  Fundamental questions addressed in this research include: 1) How will pure cultures of coastal and oceanic phytoplankton species respond to an enriched carbon dioxide environment? 2) In combined, constructed-community, mixed cultures, which species will fair better in a high carbon dioxide environment and why? And 3) Are there changes in food quality of phytoplankton resulting from shifts in species dominance?  With this research, she and her colleagues hope to provide information about species dominance under an enriched carbon dioxide environment for food web-based models.  In her spare time, she likes running 5K to marathons, hiking, cooking, and traveling.


Lisa Milke, Ph.D.

NOAA Northeast Fisheries Science Center, Milford Laboratory

Lisa Milke is a Research Fishery Biologist and the Acting Chief of the Culture Systems and Habitat Evaluation Branch at the Northeast Fisheries Science Center, Milford Laboratory. After completing her undergraduate studies in biology and environmental science, she earned a M.S. in oceanography from the University of Connecticut in 2001 and a Ph.D. in biology from Dalhousie University in 2006. Her research focuses on the feeding, nutrition, and physiology of bivalves; particularly within the areas of aquaculture and ocean acidification. She conducts research on a variety of bivalve species such as: the surf clam, Spisula solidissima, the bay scallop, Argopecten irradians, and the sea scallop, Placopecten magellanicus. Of particular interest are the physiological responses of an organism (i.e. growth, survival, energetic stores, respiration rate) to environmental stressors (i.e. ocean acidification, food availability, temperature) and how this might ultimately impact recruitment to the fishery


Adrienne Sutton, Ph.D.

NOAA Joint Institute for the Study of Atmosphere and Ocean, University of Washington

Adrienne Sutton is a Research Scientist with the NOAA Joint Institute for the Study of the Atmosphere and Ocean at the University of Washington. Her research focuses on advancing our scientific understanding of the ocean carbon cycle and the impact of rising atmospheric carbon dioxide on marine ecosystems. In particular, she maintains ocean time series observations that document the natural variability of seawater chemistry and the evolving state of ocean acidification. Adrienne also has an interest in science communication and policy, and regularly participates in venues that connect to both. After receiving her Ph.D. from the University of Maryland, she worked at NOAA headquarters in Washington, D.C. engaging the U.S. congress on issues concerning oceans and climate. As a scientist, she now strives to effectively communicate ocean acidification research in a way that contributes to an informed society equipped to face the challenges associated with global change.
