Current Research Projects
  • North Pacific waters are exhibiting shifts in composition of phytoplankton assemblages. Biochemical profiles differ among algal groups, particularly with respect to fatty acid composition, suggesting such shifts may cause changes in nutritional value of algal detritus available to consumers. Some essential fatty acids are important dietary requirements for production of eggs and development of larvae in marine invertebrates. We are investigating effects of differing algal diets on reproductive output and larval development in a commercially-harvested sea cucumbers, including investigation of fatty acids provisioned to eggs prior to spawning, and effects of maternal diet on larval development and survival.
  • Assessing benthic meiofaunal community structure in the Alaskan Arctic: A high-throughput DNA sequencing approach (North Pacific Research Board) We are conducting surveys of abundance and diversity of benthic meiofaunal invertebrates in the Chukchi and Beaufort Seas using high-throughput gene sequencing approaches. These surveys will provide essential baseline data for monitoring climate-change effects and impacts of disturbance from mineral resource extraction activities. Sediment communities are ideally suited to tracking long-term change because they tend to dampen short-term seasonal or interannual “noise” in many environmental characteristics (e.g., primary production, hydrographic features). DNA-based approaches allow for rapid assessment of meiofaunal community structure and diversity.
  • US-Canada Transboundary Fish and Lower Trophic Communities (Bureau of Ocean Energy Management) The overall goal of this project is to survey fish and essential fish habitat in the eastern part of the Beaufort Sea Outer Continental Shelf Planning Area. We are collaborating with scientists from Department of Fisheries and Oceans Canada in data collection and analysis. Goals include documentation of fish and invertebrate abundance, distribution, and habitat. My group is responsible for analysis of sediment infauna, measurements of sediment characteristics and organic matter content, and fatty acid analysis of select taxa for incorporation into food web models.
