Six Species

For about 1 penny per American per year, the Marine Mammal Commission has met its Congressional mandate to conserve marine mammals for over 50 years. 


We work to ensure that marine mammal populations are restored and maintained as functioning elements of healthy marine ecosystems in the world's oceans.

A Year in Review: the Commission's 2025 Annual Report

The Marine Mammal Commission is proud to release our 2025 Annual Report, highlighting our work and accomplishments in the previous calendar year. The Commission has published this yearly report to Congress since its inception in 1974. Within this edition, you will find information on our work to provide independent oversight, engage local communities and stakeholders on marine mammal issues, and more. This annual report was designed primarily for electronic distribution and use, directing the reader to relevant sections of our website for additional information.

Advances in Whale Tagging

In 2023, the Commission co-hosted a workshop on right whale tagging with NOAA Fisheries, the Office of Naval Research, and the Department of Fisheries and Oceans Canada. The goals of the workshop were to review key knowledge gaps and data needs regarding the movements, life history, and ecology of North Atlantic right whales (NARWs); review the history of satellite telemetry and evaluate progress in tag attachment technologies and follow-up studies; and generate knowledge to inform planning and permitting decisions regarding potential tagging of NARWs.


The workshop report identified several next steps to advance whale tagging, one of which recommended synthesizing unpublished data and information obtained from previous whale tagging studies to inform future management and permitting decisions. The Commission is pleased to share that ten peer-reviewed papers have been published in a Special Issue of the Journal of Cetacean Research and Management titled, "Cetacean Tagging: Advances and Insights," which is open for further submissions until April 30, 2026.

The Special Issue image shows a satellite-tagged humpback whale in the Gulf of Maine take by the Center for Coastal Studies (NMFS Permit 14245).

In related news, a tagging technology has been developed and tested by a workshop participant, Dr. Alex Zerbini, and coauthors. These right whale "blubber-tags" are a less invasive tool for investigating questions on right whale movements and habitat use.

Winter Highlights from Alaska

The Marine Mammal Commission works closely in Alaska with agencies, Alaska Native Organizations, academic, and other partners to support the conservation and co-management of marine mammals and their ecosystems. The Commission regularly attends marine mammal co-management meetings and related scientific workshops and symposia to stay informed on emerging conservation and management issues. Below are a few recent highlights:

 

Alaska Native Liaison Jackie Shaff attended the annual meeting of the Alaska Beluga Whale Committee with Scientific Advisor Dr. Robert Suydam, who also serves on the Alaska Beluga Whale Committee Science Team.

 

Commissioner Sue Moore and Shaff attended the annual meeting of the Eskimo Walrus Commission. The Commission’s Special Advisor on Native Affairs, Vera Metcalf, serves as Executive Director of the Eskimo Walrus Commission.

 

Commission staff attended the virtual Polar Bear Range States Meeting of the Parties, an international forum established under the 1973 Agreement on the Conservation of Polar Bears that brings together the five polar bear range states (Canada, Greenland, Norway, Russia, and the United States) to coordinate conservation and management efforts.

 

Commissioner Moore and Commission staff also participated in the Alaska Marine Science Symposium, an annual gathering in Anchorage that brings together researchers, managers, educators, students, and the public to share the latest science on Alaska’s marine ecosystems.

 

In February, Commissioner Moore, Metcalf, and Shaff presented on the Commission’s work in the Bering Strait region for Alaska Sea Grant’s Strait Science series. A recording of the talk is available on YouTube.

Highly Pathogenic Avian Influenza Outbreak in Marine Mammals

An ongoing global epizootic caused by a HPAI virus is posing serious threats for marine mammals. It has caused massive die-offs of seals and sea lions in South America, smaller die-offs in seals in North America and Europe, and sporadic deaths of dolphins in North America, Europe and South America.


The most recent outbreak is in California, at Año Nuevo State Park, where by March 15, 27 elephant seals, two California sea lions, and one sea otter have died of the virus. Read more on the University of California Davis H5 Influenza A Outbreak in Marine Mammals website for regular updates.
