Title:: Seasonal Variability in Fatty Acid and Lipid Content in the Blubber of Pacific Walruses
Geospatial_Data_Presentation_Form: tabular digital data

Description:

Abstract:: Full depth sternum blubber samples were collected from 17 adult female walruses harvested by hunting teams from the village of Gambell, Alaska. Each sample was split horizontally into two equal parts for seperate lipid content analysis of the inner and outer layers. Mean lipid conent of samples was 78.6% (standard deviation 7.1%).
Purpose:: To monitor seasonal and inter-annual condition of walruses through measures of lipid content in the blubber. This study aims to contribute to our understanding of the health and status of this vital subsistence resource, particularly with respect to rapid changes occurring in the Arctic.
Supplemental_Information:: [Provide additional information not covered elsewhere and/or important information such as related studies, data set limitations, and notifications]

Walruses were sampled by hunters from the village of Gambell, Alaska, who range throughout the Andyr straights and north into the Chirikov Basin of the northern Bering Sea.
