Photo-identification data on killer whales occupying the northern Gulf of Mexico have been collected in association with large vessel surveys since 1991. Photographs of killer whales are taken during encounters and unique dorsal fin marking can be used to identify individual animals. These images have been reviewed and individuals cataloged to evaluate residency and demographic patterns in killer whales in the northern Gulf of Mexico.

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.

This study compared morphology and body mass index (BMI) in two rough-toothed dolphin mass stranding events in Florida: August 2004 (n = 36) and March 2005 (n = 32).

The Marine Mammal and Turtle Division collects data about individual cetaceans and sea turtles that come ashore, strand on the beach, were incidentally killed in the yellowfin purse-seine fishery operating in the eastern tropical Pacific (ETP) or in the California gillnet fisheries (CAGN). The data include the species, data and location, and the sex and size of each animal. Reproductive data are also collected from some animals.

The Quarterly, Bi-annual and Annual Reports are periodic reports issued for public release. For the deep set fishery these reports are issued quarterly and anually. For the shallow set fishery these reports are issued quarterly or semi-anually, and anually.

These Marine Mammals and Sea Turtles data were gathered and utilized during the Response and Assessment phases of the Deepwater Horizon oil spill in the Gulf of Mexico. These data are for the 28 species of whales and dolphins, the Florida manatee, and the sea turtle species occurring in the Gulf, including those threatened or endangered under the Endangered Species Act: Kemp’s ridley, green, leatherback, loggerhead and hawksbill. It includes discrete samples, field observations, field photographs, telemetry tracks and related files originating from the Marine Mammals and Sea Turtles Technical Working Groups (TWGs). The data were compiled by the NOAA Office of Response and Restoration (OR&R) and Trustees in the Data Integration, Visualization, Exploration, and Reporting (DIVER) data warehouse prior to being archived by the NOAA National Centers for Environmental Information (NCEI). The collection of files include environmental data used to determine the extent and magnitude of injury to the Gulf of Mexico ecosystem from the Deepwater Horizon oil spill. These data were used as part of the Programmatic Damage Assessment and Restoration Plan (PDARP) developed through the Natural Resource Damage Assessment (NRDA) conducted as a result of the April 20, 2010 explosion and subsequent sinking of the Deepwater Horizon offshore drilling rig in the Gulf of Mexico, about 40 miles (60 km) southeast off the Louisiana coast, that led to a major oil spill in the region.

Comprises data from surveys focused on killer whales with opportunistic data from other cetacean species; includes data describing encounters for photo-identifications, biopsy, and acoustic sampling. Data includes surveys conducted by CAEP/NMML, and also contributed data from Alaska Ecosystem Program/NMML, Southwest Fisheries Science Center and other collaborators. Surveys were conducted in the Aleutian Islands, Bering Sea, and western Gulf of Alaska, 2000 to the present.

This product represents the marine mammal observation count data for the 2018-2020 Gulf of America Marine Assessment Program for Protected Species surveys and the subsequent 2022-2023 U.S. Fish and Wildlife Service aerial surveys in the northern Gulf of America. File goamapps_air_marine_mammal_observations_forDistribution.csv and both an html and xml metadata file are included. For more information, consult the associated metadata.

Aerial surveys were conducted during the spring-summer of 2010 and seasonally during 2011-2012 to assess the abundance and spatial distribution of marine mammals and sea turtles within the region impacted by the Deepwater Horizon oil spill. Surveys were conducted in high-winged twin engine aircraft flying at altitudes of 600-750 feet. Visual observations of marine mammals, sea turtles, birds, and other species are recorded including species identifications, counts of animals. Surveys are conducted along line transects oriented perpendicular to the shoreline and follow protocols consistent with analysis using Distance approaches to estimate detection probability and abundance. These data have been used to evaluate the potential impact of the Deepwater Horizon oil spill on protected species.

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.
