SWFSC Marine Mammal Survey, STAR 1998, Cruise 1612

Marine Mammal and Turtle Division, Southwest Fisheries Science Center, NMFS, NOAA

This 1998 eastern tropical Pacific cetacean line-transect survey was part of the Stenella Abundance Research Project (STAR), a multi-year cetacean and ecosystem assessment study designed to assess the status of dolphin stocks which have been taken as incidental catch by the yellowfin tuna purse-seine fishery in the Eastern Tropical Pacific. This survey was conducted by the NOAA Southwest Fisheries Science Center aboard NOAA ships David Starr Jordan, Endeavor and McArthur for a combined total of approximately 42,000 kilometers surveyed from late July to early December 1998. 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 David Starr Jordan.

The primary purpose of the survey was to collect information necessary to estimate abundance of dolphin stocks in the eastern tropical Pacific that are taken as bycatch in the yellowfin tuna purse seine fishery.
