Pelagic distribution and abundance of seabirds in the PROBES area



This data set includes data from the PROBES area, gathered by multiple observers in multiple projects, since 1975. The data were gathered in strip transects, generally 300 m wide and recorded in the data base as densities. Over that period, there has been a change in the method for recording flying birds. Before the year 2000, most, if not all, data on flying birds were recorded continuously, which can result in an inflated number of birds recorded per unit area. After 2000, most flying birds were recorded with the snap-shot method. The data in this dataset were retrieved from the USGS maintained North Pacific Pelagic Seabird Database, version 2, which is expected to be on line by late 2014, which have not been adjusted for the change in recording methods. Such a calibration was made for the Hunt et al. in press paper listed below, and information on calibration methods are in that paper and in the Renner et al paper below in related links.

This data set is part of the Bering Sea Ecosystem Study-Bering Sea Integrated Ecosystem Research Program (BEST-BSIERP). BEST-BSIERP together are the Bering Sea project.
