OCEANOGRAPHY & PRODUCTIVITY

2017

2018 PSP toxins in the Alaska marine food web Xiuning Du | Oregon State University | $389,355 This study will investigate the transfer of paralytic shellfish poisoning toxins from Alexandrium cells to zooplankton, shellfish, forage fish, and commercially important predatory fishes in Prince William Sound and Kachemak Bay. Recent data point to more intense Alexandrium blooms, higher PSP risks and trophic transfer of toxins through the food web. Hot spots of activity in the cold ocean Roy Collins | University of Alaska Fairbanks | $174,940 This project targets the lower trophic levels that have not previously been surveyed (bacteria, archaea, and fungi) using novel DNA sequencing technologies. Specifically, the study will address the transport, composition, and distribution of the microbial communities that drive important processes on the Arctic shelves, including growth, respiration, and deposition.

Oceanography & Productivity Funding Metrics

Mixotrophy in the coastal Gulf of Alaska (CGOA) Suzanne Strom | Western Washington University $129,865 This project investigates the abundance, biomass, prev- alence, and identification of mixotrophs among CGOA plankton, namely ciliates and dinoflagellates along the Seward Line and in Prince William Sound. The prevalence of mixotrophy has important implications for the mech- anisms by which this coastal ecosystem sustains high abundances of upper trophic level species.
