Tissues and samples collected from marine mammals during investigation of the Northern Gulf of Mexico Marine Mammal Unusual Mortality Event are tracked within this database. These include a broad variety of tissues and associated analyses. The database is used to track to collection, disposition, storage, and analytical results of each sample. These data have been used to evaluate the causes of mortality associated with the Northern Gulf of Mexico Unusual mortality event.

To document interactions and harvesting of marine mammals by fishing vessels in which there is an observer aboard

Critical habitat includes all marine waters within the delineated boundaries. For the inland waters of Washington state (2006 designation), the contiguous shoreline is defined by the line at a depth of 20 feet (6.1 meters) relative to extreme high water. For the coastal marine waters along the U.S. west coast (2021 revision), the contiguous shoreline is defined by the line at a depth of 20 feet (6.1 meters) relative to mean high water. See the final rules (71 FR 69054 and 86 FR 41668) for descriptions of areas excluded from this critical habitat designation. For the inland waters of Washington state (2006 designation), military areas excluded due to national security impacts were not clipped out of the data.For the coastal marine waters along the U.S. west coast (2021 revision), military areas excluded due to national security impacts (i.e., the Quinault Range and its 10 kilometer buffer) were clipped out of the data.

SRKW were listed as endangered in 2005. This study collected baseline data about the industry to be able to determine social impacts to the industry as a result of the SRKW listing. Primary data was collected, analyzed, and reported. Northwest Regional Office and Protected Species Office staff used some study results in an Environmental Assessment completed in 2011. This information will also be used to compare future data collections to measure social changes as a result of new vessel regulations. Primary qualitative/quantitative dataset.

This data set contains sensitive biological resource data for seals, whales, porpoises, walruses, sea otters, and Steller sea lions in the Bristol Bay Subarea. The Subarea includes marine and coastal areas of Bristol Bay and part of the southern Alaska Peninsula. (This area extends from directly south of Goodnews Bay to slightly north of Port Seniavan along the Bristol Bay side of the Alaska Peninsula, as well as the Pacific Ocean side of the Alaska Peninsula from Cape Providence to Kupreanof Peninsula.) Vector polygons in this data set represent marine mammal distribution, haul-out sites, and rookeries. Species-specific abundance, seasonality, status, life history, and source information are stored in relational data tables (described below) designed to be used in conjunction with this spatial data layer.This data set comprises a portion of the Environmental Sensitivity Index (ESI) data for the Bristol Bay Subarea. ESI data characterize the marine and coastal environments and wildlife by their sensitivity to spilled oil. The ESI data include information for three main components: shoreline habitats, sensitive biological resources, and human-use resources. See also the M_MAMPT (Marine Mammal Points) data layer, part of the larger Bristol Bay Subarea ESI database, for additional marine mammal information.

Compilation of the data that go into the annual marine mammal stock assessment reports, including abundance and bycatch estimates, PBR calculations, bibliographic references, update history, and serious injury determinations.

The Marine Mammal Protection Act formalized a program to provide response to reports of strandings of marine mammals and unusual mortality events. This was done by creating a network of parties from different locations that would be responsible for responding to stranding events within their zone. Most stranding zones in California are defined by county boundaries. Some zones include only one or two counties, but California's largest zone covers 8 coastal counties and includes another 10 where the San Francisco Bay and Sacramento - San Joaquin River Delta reach inland. Los Angeles county has its coastline divided into two stranding zones, and one of those two zones also has multiple (2) organizations responsible for strandings within it.Stranding reporting areas of the coast of Oregon and Washington and Puget Sound are based upon the authorizations for each facility in their Stranding Agreement (SA) - each SA lists a primary response area granted to the organization, and these lines correspond to that. These zones are often divided more by geographical considerations than by political boundaries, such as island groups or cross-water zones. One zone is the responsibility of two different organizations because each has a different specialty. The Cascade Research Collective is responsible for Cetacean strandings in that area and Washington Department of Fish and Wildlife Marine Mammal Investigations is responsible for pinniped strandings in the same area.A stranding is:• a dead marine mammal on the beach or in the water;• a marine mammal that is alive on the shore and unable to return to the water under its own power;• a marine mammal that is alive on the shore and, although able to return to the water, is in need of apparent medical attention;• a marine mammal in the water and cannot return to its natural habitat under its own power or without assistance.In most stranding cases, the cause of the stranding is unknown, but some identified causes have included disease, parasite infestation, harmful algal blooms, injuries from ship strikes or fishery entanglements, pollution exposure, trauma, and starvation. While most stranded animals are found dead, some strand alive. In a limited number of cases it's possible to transport them to regional rehabilitation centers for care. In rare cases, successfully rehabilitated animals are returned to the wild. With the passage of the Endangered Species Act, in 1973 and the Marine Turtle Conservation Act of 2004, protection of sea turtle species, most of which are endangered or threatened, has resulted in them being added to the list of species which stranding organizations are responsible for.

On May 19, 2015, a pipeline owned ruptured in Santa Barbara County, California, near Refugio State Beach. An estimated 21,000 gallons of the oil flowed overland from the break site into the Pacific Ocean and spread across the marine environment. NOAA and our state and federal partners are investigating these impacts and will determine the amount of restoration needed to return the environment to the condition it was in before the spill and to compensate the public for environmental degradation from the time of the spill until recovery. This layer is the GPS track-line of a boat that was used to conduct marine mammal surveys and their possible interaction with oil from the Refugio Beach Oil Spill.

This database represents a summary of information on stranded marine mammals reported to NMFS throughout the State of Alaska in fulfillment of Title IV of the Marine Mammal Protection Act. These data include live and dead reports for cetaceans and pinnipeds.
