Recorded Video Talk: Pacific Walruses: Responding to Change? Strait Science, April 2023
USGS and USFWS biologists conducted a series of joint research cruises from 2013-2017 to study Pacific walrus population dynamics. This joint presentation is on past, current, and future Pacific walrus research in the Bering Strait including results from these research cruises, the 2023 field season, and the upcoming 2024 research cruise.

This is B-roll video collected during the fall of 2024 on the Alaskan shores of the Chukchi Sea.
Sounds from a large herd of walruses resting on Alaskan shores of the Chukchi Sea recorded. Deep full barks and calls of individual walruses near the edge of the herd are audible over a continuous rhythmic humming sound that arises from the calls of tens of thousands of walrsues from deeper within the herd.

USGS uses small uncrewed aerial systems, also known as drones for science, to survey walrus herds and carcasses on remote Alaskan beaches. The USGS visual observer, Christina Ahlstrom, keeps her eyes on the survey drone while the remote pilot prepares it to survey the walrus herd that is visible in the distance behind her on the beach.

USGS is flying drones for science, small uncrewed areal systems (sUAS), to surveys walruses when they rest on shore. The sUAS makes minimal sound due it is broad wing and is flown high above the walrus herds to enables survey data collection with minimal risk to walruses.

Figure showing two Capella Space Synthetic Aperture Radar (SAR) satellite images of a walrus haulout in Russia during and after walrus occupancy. USGS has found that SAR imagery can detect walruses when they rest on shore in large numbers and is pursuing studies to understand how satellite imagery can support improved management of the Pacific walrus.
