Abstract:
This 1986 eastern tropical Pacific cetacean line-transect survey was the first in a series of annual surveys (1986-1990) designed to monitor and detect trends in populations of dolphins killed in the yellowfin tuna purse seine fishery. This survey was conducted by the NOAA Southwest Fisheries Science Center aboard NOAA ships <i>David Starr Jordan</i> and <i>McArthur</i> for a combined total of approximately 30,000 kilometers surveyed from late July to early December 1986. 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 by the NOAA Ship <i>McArthur</i>.
