The marine mammal habitat-based density models for the Atlantic Ocean and Gulf of Mexico currently featured in MarineCadastre.gov are outdated, and new models will be available online later in 2015. These new models are being developed by Duke University’s Marine Geospatial Ecology Lab in partnership with NASA, the NOAA Cetacean & Sound Mapping project, and the U.S. Navy. The marine mammal data layers currently in MarineCadastre.gov represent habitat-based model estimates of animal density. The model results show estimates of the average number of animals per square kilometer during a given season. Most average estimates per square kilometer feature less than 1.0 animal because marine mammals are highly mobile and often occur in large groups. An average value of 0.5 bottlenose dolphins per square kilometer during the summer could mean a number of things. For example, it could mean that one animal would be present every other day; one group of five animals would be present once in a 10-day period; one group of 50 animals would be present every 100 days; and so forth. For more information on the current models, view the “Uses” or “Publication” options under the “Uses and Metadata” button for the marine mammals data sets.
This layer is a component of Marine Mammals and Sea Turtles.

This map service presents spatial information about MarineCadastre.gov services across the United States and Territories in the Web Mercator projection. The service was developed by the National Oceanic and Atmospheric Administration (NOAA), but may contain data and information from a variety of data sources, including non-NOAA data. NOAA provides the information “as-is” and shall incur no responsibility or liability as to the completeness or accuracy of this information. NOAA assumes no responsibility arising from the use of this information. The NOAA Office for Coastal Management will make every effort to provide continual access to this service but it may need to be taken down during routine IT maintenance or in case of an emergency. If you plan to ingest this service into your own application and would like to be informed about planned and unplanned service outages or changes to existing services, please register for our Data Services Newsletter (coast.noaa.gov/digitalcoast/publications/subscribe).
