NPPSD Sampling Effort Maps

Geographic coverage of the transect samples in NPPSD

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.
