North Pacific Pelagic Seabird Database

Science Center Objects

The North Pacific Pelagic Seabird Database (NPPSD) includes more than 460,000 survey transects that were designed and conducted by numerous partners primarily to census seabirds at sea.

The North Pacific Pelagic Seabird Database (NPPSD) is maintained by the USGS and includes more than 460,000 survey transects that were designed and conducted by numerous partners primarily to census seabirds at sea. The current database contains abundance and distribution information on over 20 million birds comprising 160 species observed over 40 years in a region of the North Pacific exceeding 25 million square kilometers. This area includes more than 80% of U.S. continental shelf waters, the most productive U.S. commercial fishery, all Pacific U.S. marine sanctuaries, and Alaska Outer Continental Shelf oil and gas leasing areas. Survey efforts include international cooperation between the United States, Canada, Russia, and Japan.

The NPPSD is a powerful tool for examining abundance and distribution of seabirds across marine ecosystems of the Arctic and North Pacific and possible drivers of change to seabird ranges and populations, such as climate, commercial fisheries, vessel traffic and oil and gas development. NPPSD data are available from USGS at the links below.

Making data contributions

The North Pacific Pelagic Seabird Database (NPPSD) is managed by the USGS Alaska Science Center and ishas been compiled from thousands of at-sea surveys of seabirds and marine mammals conducted in the North Pacific beginning sincein 1973 by numerous partners. The NPPSD is managed by the U.S. Geological Survey Alaska Science Center. While we are continually accepting and archiving datasets, we are beginning a major update of the database and are soliciting contributions of at-sea data from researchers. Contributors can provide us with raw, cleaned datasets or thosedata summarized intoby transects. Note, wWe do not distribute raw data,  and only provide summarized data (by transect and behavior) data through the NPPSD. The document, "NPPSD Data Prep.pdf - [PDF file 34 KB]", provides detailed information regarding data preparation for eventual addition to the NPPSD. Note, if your data is in a very different format or you are unclear as to any detail regarding data formats, contact Gary DrewContact Gary Drew gdrew@usgs.gov for assistance.
