NOAA Alaska Fisheries Science Center’s Ice Seal Research in the Eastern Bering Sea Aboard the NOAA Ship Oscar Dyson
NOAA’s Alaska Fisheries Science Center’s (AFSC) studies Alaska’s marine ecosystems to ensure the sustainable use and conservation of living marine resources in federal waters. A recent study done by NOAA scientists focuses on surveying ice seals, with the primary goal of deploying non-invasive, low-disturbance methods for monitoring the body condition of Arctic seals as an indicator of population health and productivity. This work complements and expands the capabilities of NOAA’s existing large-area photographic surveys to monitor Arctic seal populations and their responses to a rapidly changing environment. The methods and techniques developed throughout this project will greatly enhance NOAA Fisheries capabilities to assess the status and trends of bearded, ringed, spotted, ribbon, and harbor seals in Alaska, as well as meet the agency’s responsibilities under the Marine Mammal Protection Act (MMPA) and Endangered Species Act (ESA). From April 8th-25th 2022, researchers with the The Polar Ecosystems Program (PEP) embarked on the NOAA AFSC ice seal research expedition aboard the NOAA Ship Oscar Dyson in the eastern Bering Sea.
