I am a fisheries oceanographer investigating ecosystem responses to climate variability and change. This research involves consideration of theory, observations (time series and process studies), and models.

I explore changes in physical, biogeochemical, and planktonic characteristics that are evident in long, observational records and simulated by atmosphere-ocean general circulation models. I hope to compare and distinguish impacts of anthropogenic climate change from those of natural variability and resolve how such changes influence fisheries productivity. By considering the range of possible future changes in the nutrient composition, carbonate system, oxygen content, and structure of planktonic communities, I hope to better understand the implications of long-term climate changes for the productivity of living marine resources.

Areas of focus include:

Understanding long-term changes in upwelling ecosystems; Large-scale variability in oceanic and atmospheric processes of the North Pacific; Remote forcing of coastal conditions; Ocean acidification and deoxygenation; Size-structured interactions in ocean ecosystems

Current opportunities:

2017-2018 Postdoctoral position in Fisheries oceanography:
The School of the Earth, Ocean, and Environment at the University of South Carolina and the Nippon Foundation-Nereus Program are seeking a postdoctoral fellow to join our interdisciplinary team of researchers to explore the responses of forage fish populations in eastern boundary upwelling ecosystems to physical and biogeochemical variability associated with future climate change. The goal of the project is estimation of fisheries productivity given projected changes in upwelling intensity and seasonality, nutrient stoichiometry, acidification, and plankton production and composition. If interested, please see the information posted here.

Graduate student positions in Marine Ecology, Climate Change, and Biological Oceanography:
Applications for graduate studies at the MS and PhD levels are being accepted through the Marine Science Program and the Department of Biological Sciences. Potential students interested in studying the interactions among marine ecosystems, fisheries, and climate should contact Ryan by email with a CV and a brief statement about research interests. Please note the application deadlines for these programs are typically in January or February prior to the initial fall semester, but applications for external funding are oftentimes due in the preceding November.

Specifically, the lab is looking for a student interested in exploring the 1) responses of marine communities to changes in the location and seasonal timing of upwelling; and 2) statistical descriptions of changing empirical relationships between physical ocean characteristics and populations of commercial fishes in the North Pacific.

Undergraduate student positions:
We are stuffed to the gills with great undergraduate researchers for the current semester, and new letters of interest will be reviewed for positions beginning fall of 2017. If you are interested in gaining experience in projects related to ecosystem oceanography and modeling beginning in summer, please forward a brief letter of interest and CV to Ryan at ryk@sc.edu.
