NPPSD Sampling Effort Maps
Geographic coverage of the transect samples in North Pacific Pelagic Seabird Database (NPPSD). Samples from Version 1.0 release are represented by dark blue points; samples added in the Version 2.0 release are represented by light blue points; samples added for Version 3 are represented by dark yellow points.

North Pacific Pelagic Seabird Database (NPPSD)
The North Pacific Pelagic Seabird Database (NPPSD) was created in 2005 to consolidate data on the oceanic distribution of marine bird species in the North Pacific. Most of these data were collected using at-sea strip-transect surveys within defined areas and at known locations. The NPPSD also contains observations of other bird species and marine mammals. The original NPPSD combined data from...
