Assessing effects of climate change and ocean acidification on sea urchin productivity and trophic interactions in the Aleutian Islands; Consequences

We propose using an existing, longterm data set of sea urchin production, sea otter performance, and ecosystem state metrics from the last 30 years tobuild a spatially explicit sea otter population viability analysis (PVA) model, incorporating climate change effects. We propose a 3-pronged approach in year 1 of this project to evaluate (obj. 1) variability in sea urchin demographics over space and time to identify scaledependent patterns of variation in production using existing datasets, (obj. 2) define the direct effects of climate change and ocean acidification on sea urchin productivity through indepth literature review and contributions from experiments by collaborators, and (obj. 3) determine how effects of...

Sea Otter Spraint Data from Kachemak Bay, Katmai National Park and Preserve, Kenai Fjords National Park and Prince William Sound

These data are part of the Gulf Watch Alaska (GWA) long-term monitoring program. This dataset consists of observations of sea otter (Enhydra lutris) fecal samples (spraint). Observers examined fresh spraint piles to identify major prey classes in the samples and to determine sea otter diets in the Gulf of Alaska region.
