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 conent 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.
