Biologists conducted survey flights of the shifting sand shoals of the Copper River Delta to search for marine mammal carcasses and to conduct necropsies of any observed carcasses in order to establish the cause of death and collect biological samples.
This report summarizes the results of the habitat modeling effort whose primary objective was to collect cetacean sighting data to support the derivation of cetacean density estimates.
Abundance estimates are needed to evaluate the impacts of human activities in population assessments of cetaceans. HICEAS is a recurring ship-based, line-transect survey designed to estimate cetacean abundance in the entirety of the Hawaiian EEZ.
NOAA Fisheries released the 2017 National Report of Marine Mammal Strandings in the United States. Marine mammals strand for a variety of reasons, and NOAA Fisheries tracks this data to monitor threats to wild marine mammal populations.
Each year, NOAA Fisheries collects, verifies, documents, and responds to reports of large whale entanglements. The 2020 U.S. West Coast reports, and other relevant information and developments are included in this summary.
Draft Environmental Impact Statement, Regulatory Impact Review, and Initial Regulatory Flexibility Analysis for Amending the Atlantic Large Whale Take Reduction Plan: Risk Reduction Rule
This plan represents a cooperative effort to identify, prioritize, and implement management measures necessary to improve food security on St. Paul Island and conserve marine mammal species used for subsistence purposes.
