SWFSC Cetacean Acoustic Detection and Dive Interval Studies (1601)

This study was conducted by the NOAA Southwest Fisheries Science
Center primarily in the southern Gulf of California aboard NOAA research ship
McArthur from early September to early November 1995 for a total of
approximately 6,000 kilometers surveyed. The project focused on two potential
approaches to improve abundance estimates of long-diving whales: (1) acoustic
detection of diving animals, and (2) collecting dive interval data on those
species to serve as a basis for a model-based abundance correction factor. This
dataset provides the time-date and geographical coordinates, by species/stock,
of all cetaceans detected during the survey, as well as the daily and
intra-daily start and end points of the line-transect survey.
