The data consist of blood chemistry and hematology from sea otters captured at sites along the Aleutian archipelago, the Alaska Peninsula, the Gulf of Alaska, and Prince William sound between 2004 and 2012. The data include the blood chemistry and hematology findings as well as general capture location, if the sea otter population in that area is declining, capture date, age estimate, age class, sex, and a unique sea otter number connecting the sample to gene expression data.

The data table consists of a compilation of sea otter survey results from Bering Island, Russia and select Western Aleutian Islands conducted between 1959 and 2015. The counts were reduced to sea otters per kilometer of coastline for temporal comparability. A correction factor of 3.6 was applied to aerial survey totals to yield results comparable to skiff based surveys. The data table provides the island, year, mode (aerial, skiff, or ground), and shore length covered in each survey. Counts of independent otters and pups are provided if available. Total otters counted or calculated with the correction factor and the calculated linear density are also provided.

The table presents summary data of sea otter skulls found on carcass searches conducted along stretches of shoreline at islands or locations along a longitudinal span encompassing the sea otter population decline. Numbers of skulls encountered, length of shoreline searched, population density calculated from survey data, as well as skulls per kilometer and per-capita recovery rate are presented. The data are arranged in west to east order from Bering Island to Prince William Sound.
