This survey was conducted by the NOAA Southwest Fisheries Science Center aboard the NOAA ship McArthur for a total of approximately 12,000 kilometers surveyed from early March to early June 1997. 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.
