The 2008 Oregon, California and Washington Line-Transect Experiment (ORCAWALE) was designed to estimate the abundance of and to describe the distribution of dolphins, whales, and porpoises off the west coast of the United States out to 300 nautical miles. This survey was conducted by the NOAA Southwest Fisheries Science Center aboard the NOAA Ship McArthur II for a total of approximately 12,800 kilometers surveyed from late July to the end of November 2008. 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.
The primary purpose of this survey was to estimate the abundance of and to describe the distribution of dolphins, whales, and porpoises off the west coast of the United States out to 300 nautical miles.
