SWFSC Marine Mammal Survey of the Eastern Tropical Pacific (1081)

This 1987 eastern tropical Pacific cetacean line-transect survey was
the second 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 David Starr Jordan and McArthur for a combined
total of approximately 29,000 kilometers surveyed from late July to early
December 1987. 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.
