Data on the pelagic distribution and abundance of seabirds are critical for understanding the basic ecology of marine birds, monitoring population trends, assessing impacts of human activities, identifying critical marine habitats, and educating the public about seabird conservation. To address these needs, the U.S. Geological Survey and U.S. Fish and Wildlife Service have undertaken the task of consolidating and providing comprehensive geographic data on the pelagic distribution of seabirds in Alaska and the North Pacific.

Recent Changes

    • A revised and expanded NPPSD Species List ver. 2.1 is now available on our Products page. The current version of the NPPSD code list contains 335 unique taxa and include 4-letter codes, common names, ITIS taxonomic serial number, and NODC taxonomic code for marine birds and mammals observed on surveys in the NPPSD dataset. This list is provided to further the goal of standardizing pelagic seabird data. Researchers are encouraged to use this list for marine bird and mammal surveys in the North Pacific.
    • Maps have been added to the North Pacific and Alaska pages.

The North Pacific Pelagic Seabird Database (NPPSD) v1.0, collected data from researchers in Canada, Russia, and the U.S. (1973-2003). Currently we are working on version 2.0 of the NPPSD which should be available later in 2013. The new version includes data from 1973-2013.

If you have or know of data you would like to incorporate into this database please contact project manager John Piatt ( or database manager Gary Drew (
