Jeff Dorman, Ph.D.
Post-Doctoral Research Associate
Jeff is a biological oceanographer who is interested in the drivers of zooplankton variability in the northern California Current. Jeff completed a Masters degree at San Francisco State University working on the response of krill to upwelling events and his Ph.D. in Integrative Biology at the University of California at Berkeley. His dissertation research involved running physical oceanographic models (ROMS) and interfacing the output with biological individual-based models of the krill species Euphausia pacifica. Jeff’s current research is an extension of this modeling work to better understand the conditions that lead to boom and bust cycles of this important prey species of the California Current.
Marisol Garcia-Reyes, Ph.D.
Post-Doctoral Research Associate
Native to Mexico and with a physics background, Marisol completed her Ph.D. in atmospheric sciences at the University of California, Davis in 2011. Her research focused on coastal upwelling variability in time and space along the California coast, how climate impacts upwelling-favorable winds and the ocean’s response to them (Garcia-Reyes and Largier 2010), and how upwelling and climate variability impact the marine ecosystem. Currently she is studying how winter and early spring variability in upwelling impacts biological productivity, what drives this variability and how it will be affected by global warming.
Jason Hassrick, Ph.D.
Post-Doctoral Research Associate
Jason completed his Ph.D. on the foraging ecology of northern elephant seals in the Ecology and Evolutionary Biology program at UC Santa Cruz in 2011. He initially joined the Farallon Institute to work on Brandt's cormorant breeding ecology with Julie Thayer at Alcatraz Island and has since moved onto analyzing krill distributions in the California Current using echosounder data from NOAA ship surveys. Jason was recently granted a post doctoral fellowship from the Delta Stewardship Council to work with Sean Hayes at NOAA's Southwest Fisheries Science Center to study the outmigration survival and movement of Chinook salmon smolt runs out of the Sacramento River and Delta. As part of his research, Jason investigates physical and biological determinants of krill-salmon covariation in the California Current System.
Adele Paquin, M.Sc. Candidate
Research Associate
Adele was first introduced to biological oceanography when she sailed on a five-week oceanographic cruise with Sea Education Association in the eastern tropical Pacific. She returned to land to complete a B.A. in Biology from Hamilton College, then moved to California to conduct research with Dr. Karina Nielsen on how oceanographic conditions mediate ecological interactions in the rocky intertidal. Adele entered the M.Sc. program at Sonoma State University in order to follow her interest in biological oceanography, and studied the event- and seasonal-scale forcing of surfzone phytoplankton community composition and abundance. Her current interest is in studying how phytoplankton links oceanographic conditions with patterns in secondary production and higher trophic organism communities.
Sonia D. Batten, Ph.D.
Collaborator
Sonia completed her PhD. at the University of Southampton, UK in 1994. After working with the North Atlantic Continuous Plankton Recorder (CPR) data set at the Sir Alister Hardy Foundation for Ocean Science (SAHFOS) for six years she transferred to the west coast of Canada to set up and coordinate the Pacific CPR survey. Sonia is a biological oceanographer with a focus on zooplankton and their role as indicators of the marine environment (Batten and Welch, 2004) and their place in the food chain (Batten et al. 2006). The Pacific CPR survey has completed its eighth year of sampling and in that time has collected plankton along transects totalling over 200,000 km of the north Pacific.
Bryan Black, Ph.D.
Collaborator
Bryan is an Associate Research Professor at Oregon State University’s Hatfield Marine Science Center in Newport, Oregon. He completed his Ph.D. in Forest Resources at Penn State University in 2003 and applies dendrochronology (tree-ring analysis) techniques to growth increments of long-lived marine organisms including fish, bivalves, and corals. Resulting growth-increment chronologies can be used to establish the effects of climate on growth, reconstruct climate variability prior to the start of instrumental records, and make comparisons across species and ecosystems. Bryan has been particularly interested in integrating diverse biological indicators, including chronologies, to investigate the impacts of climate variability on marine and terrestrial ecosystems of the northeast Pacific. In the California Current, for example, rockfish (Sebastes spp.) growth-increment chronologies covary with records of seabird reproductive success, independently corroborating the importance of wintertime climate variability to upper-trophic productivity (Black et al. 2011).
Michael Henry, Ph.D.
Collaborator
Mike completed his Ph.D. in phytoplankton ecology and biodiversity at the University of British Columbia, Vancouver, in 2005. Currently residing in Montreal, Canada, Mike’s research is focused on the macro-ecology (large-scale distribution and abundance) and interactions of phytoplankton, zooplankton, and marine birds in the North Pacific (Batten et al. 2006, Hyrenbach et al. 2007). In his current research, Mike is determining how lower trophic level diversity and production influences seabird diversity and abundance between the Gulf of Alaska, southern Bering Sea, and western Pacific gyre, and assessing the effects of climate variability and change on these North Pacific ecosystems. Since 2002, Mike has spent over 330 days at sea on the container ship M/V Skaubryn surveying seabirds and marine mammals and deploying a Continuous Plankton Recorder 3 times per year along a 7,500 km transect stretching from Victoria, British Columbia to Tokyo, Japan.
Kyra L. Mills, M.Sc.
Collaborator
Raised in Ecuador, Kyra received her graduate degree from the University of California Irvine, where she studied the behavior of seabirds in the inshore waters of the Galápagos Islands, including the foraging ecology of Galápagos Penquins using time-depth recorders. Kyra worked as lead biologist on the Farallon Islands, California between 1999-2001. With great interest in the concept of seabirds as indicators and predictors of forage fish populations, Kyra and collaborators (Mills et al. 2007) developed the "multivariate rockfish index" (MRI), a novel method to assess rockfish productivity in the central-northern California coastal marine environment. Kyra has also worked on seabirds as indicators of the ecosystem conditions that influence the survival of salmonids and herring during the ocean-going phase of their life cycle (Roth et al. 2007). Kyra wrote, edited, and coordinated the California Current Marine Bird Conservation Plan, an ecosystem-based approach for seabird conservation along the west coast of North America.
