This survey was conducted by the NOAA Southwest Fisheries Science Center aboard NOAA Ship <i>McArthur</i> for a total of approximately 10,000 kilometers surveyed from late July to early November 1991. 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.
