Data Center Description
The National Marine Mammal Laboratory (NMML) is responsible for
conducting research on marine mammals important to the mission
of the National Marine Fisheries Service (NMFS) and the National
Oceanic & Atmospheric Administration (NOAA), with particular
attention to issues related to marine mammals off the coasts of
California, Oregon, Washington and Alaska. This work includes
stock assessments, life history determinations, and status and
trends. Information is provided to various U.S. governmental and
international organizations to assist in developing rational and
appropriate management regimes for marine resources under NOAA's
jurisdiction. Research programs are carried out cooperatively
with other Federal, state and private sector agencies.

Research conducted by the NMML utilizes a variety of methods and
tools to obtain needed information. Determination of status and
trends of marine mammal populations requires information on
abundance, stock structure, mortality and net productivity. To
obtain these data, censuses are carried out from ships, aircraft
and on land. Radio and satellite-linked telemetry is utilized to
determine movements and migrations, critical feeding areas and
depths, and other behavioral data. Sophisticated analyses and
modeling are carried out to determine necessary population

Information is provided to the NMFS Alaska and Northwest
Regional Offices, and to the Office of Protected Resources. NMFS
is also required to provide data to the North Pacific Fisheries
Management Council (NPFMC), the U.S. Fish and Wildlife Service,
and to other commissions established under treaties.

Marine mammal stock assessment information is published annually
by NMML staff and is available here. Information included in the
Stock Assessment Reports for Alaska marine mammals is reviewed
by the Alaska Scientific Review Group.
