National Stranding Database Public Access

Includes information on every stranded marine mammal in the United States that a member of the National Stranding Network has responded to. Data include species, approximate age, sex, date, location, condition/determination, and other information.


Thanks for your interest in marine mammal stranding data. At this time, access to the Marine Mammal Health and Stranding Response Program’s National Stranding Database is only granted to participants active in the national stranding network.

If you are a member of the national stranding network and require access, please work with your regional stranding coordinator to make that request. If you are not a member of the national stranding network, NOAA Fisheries can run queries of the database for you and provide the results in an Excel file.

The National Stranding Database collects the fields on the Level A Stranding Report (Download File). This form is completed for every stranded marine mammal that a member of the stranding network responds to in the United States.

To perform a query, we need to know which information and data from the Level A form you are interested in receiving—generally a date range and a geographic area, as well as species or groups of species.

An example query request would be:

Species, Date of Initial Observation, Location of Stranding, Condition at Initial Observation, Sex, Age Class, and Condition/Determination for all cetacean strandings in Maine, New Hampshire, and Massachusetts from 2010 to 2015.

Please send database query requests
