Nearshore Marine Ecosystem Research
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...

USGS Research Vessel Alaskan Gyre
The R/V Alaskan Gyre is a 50-foot fiberglass seiner that has been converted into a versatile research vessel to provide USGS scientists and collaborators with access to remote marine areas of Alaska and serve as a mobile laboratory. The vessel was built by Ledford Marine of Marysville, Washington in 1989 and is named after the Alaskan Gyre, a series of wind driven currents that rotate counter...

Density estimate of sea otters in southcentral Alaska
Density estimate of sea otters in southcentral Alaska from aerial surveys flown in 2014, 2017, and 2019. Sea otters in southcentral Alaska are the northernmost stock of sea otters and a keystone predator because they are known for structuring nearshore marine ecosystems through their feeding habits. Biologists with the USGS and USFWS conducted aerial
