Nearshore Marine Ecosystem Research Program

Nearshore ecosystems include many resources that are of high ecological, recreational, subsistence, and economic value. They also are subject to influences from a wide variety of natural and human-caused perturbations, which can originate in terrestrial or oceanic environments. Our research is designed to evaluate sources of variation in the nearshore and how they influence resources of high conservation interest. Our studies address community members at every trophic level, ranging from intertidal macroalgae and kelps to benthic invertebrates to top-level predators such as sea otters, black oystercatchers, and sea ducks. Key issues addressed by our program includes ecosystem recovery from the Exxon Valdez oil spill; in particular, studies of sea otters and harlequin ducks have provided unprecedented insights into the processes and timelines of recovery of vulnerable species. We also have a long history, and ongoing efforts, evaluating population dynamics of sea otters and their effects on other components of nearshore ecosystems. Recovery of otters following near extirpation during the fur trade has allowed consideration of the top-down effects of otter predation, as well as factors that limit sea otter populations. We also study sea ducks, a group of waterfowl of high conservation concern, evaluating factors on marine habitats that influence their distribution, abundance, and demography. A large component of our program is participation in Gulf Watch Alaska, which is designed to monitor marine ecosystem structure and function in the northern Gulf of Alaska. The geographic scope of our work includes a huge swath of subarctic coastline, spanning from the Aleutian Islands through Southeast Alaska, with collaborations along the entire Pacific coast of North America.
