资源简介：
As a part of the GLOBEC-Northeast Pacific project, line-transect surveys of cetaceans were conducted on two cruises to northern portion of the California Current System (coastal Oregon and Northern California).
Observations were conducted from the flying bridge during daylight (~0600-2030) whenever sufficient visibility (i.e., > 2 nm) and weather (i.e., < Beaufort 6) allowed. Two observers simultaneously surveyed to the horizon with 25 x 150 binoculars, equipped with compass and reticle. Each observer surveyed a 100 degrees arc from 10 degrees off the bow (opposite side) to 90 degrees on their side of the ship. A third observer focused on the track-line by eye, aided with 7 x 50 hand-held binoculars. Sightings were entered immediately on a laptop computer connected to the ship's GPS system. Positions of all sightings were corrected to reflect the actual location of the cetaceans, rather than the ship's position. (For additional information see reference section).
