Description:

"The abundance of most cetaceans along the US West Coast was estimated from data collected on a 2008 ship-based survey. Line-transect methods were used on the survey, and analyses were based on the multiple-covariate line-transect approach used by Barlow and Forney (2007) in their analysis of previous West Coast Surveys. Shortbeaked common dolphins, long-beaked common dolphins and Dall's porpoises were the most abundant small cetaceans with abundances of ~370,000, ~62,000 and ~30,000 (respectively). Fin whales and humpback whales were the most abundant large whales, with abundances of ~3,000 and ~1,000 (respectively). In total, abundances were estimated for 17 cetacean species plus several categories of cetaceans that could not be identified to species"--Abstract.
