Marine mammal data collected during a survey in the eastern tropical Pacific Ocean aboard the NOAA ships McArthur II and David Starr Jordan, July 29 - December 10, 2003

"The primary objective of the study was to estimate abundances of the dolphin stocks affected by the ETP purse-seine fishery for yellowfin tuna (Thunnus albacares). The survey's design targeted the depleted stocks of eastern spinner dolphins (Stenella longirostris orientalis) and the northeastern offshore stock of spotted dolphins (Stenella attenuata). In addition to data suitable for line-transect analysis, behavioral, acoustic, photogrammetric, genetic, morphological, and individual whale identification data were collected on the region's cetaceans and are described in this report"--Survey objectives (page 2).
