The SWFSC began an Ecosystem Survey of Delphinus Species cruise 07 September 2009 aboard NOAA Ship McArthur II. This research cruise will focus on the two species of common dolphin found off the coast of California: the long-beaked common dolphin and the short-beaked common dolphin. Our primary objectives are to estimate abundance, reproductive rates and contaminant concentrations, and to characterize the habitat of these species. The study area is largely defined by the distribution of long-beaked common dolphins, a coastal species that ranges from about Monterey Bay, California, south to about Cabo San Lucas at the tip of Baja California, Mexico. Dr. Susan Chivers is chief scientist for the cruise. More information is available at http://swfsc.noaa.gov/prd-delphinus.aspx.
