Arctic sunrise over resting walruses
Detailed Description
A dim light shines during the summer Arctic morning in the Chukchi Sea as groups of Pacific walruses rest. USGS and the U.S. Fish and Wildlife Service conducted joint research expeditions in 2023, 2024, and 2025 to collect data on the Pacific walrus population. Skin biopsy samples are collected from walruses hauled-out on sea ice to help scientists estimate population abundance and trend. Age structure data is also collected from walruses hauled-out on sea ice, which will help scientists estimate survival. MMPA Permit 33776D.
