2007 West Coast Ocean Acidification Cruise

The 33-day NACP West Coast Cruise on the R/V Wecoma started on May 11 in Newport, Oregon, and ended on June 14, 2007 in San Diego, California. During the cruise, a total of 111 stations along 13 transect lines orthogonal to the coast were sampled, extending from Queen Charlotte Sound, British Columbia, Canada, in the north, to San Lazaro Bay, Baja California, Mexico, in the south. Water samples collected with a 24-bottle rosette at each CTD station were analyzed for salinity, oxygen, nutrients, dissolved inorganic carbon, total alkalinity, dissolved organic matter, colored dissolved organic matter, particulate organic carbon, biogenic silica, and chlorophyll. Underway measurements of atmospheric pCO2, near-surface seawater pCO2, and bio-optical properties were also made along the cruise track. Chief Scientists were Dr. Richard Feely and Dr. Christopher Sabine.  Key results from this cruise have been published in Feely et al. (2008) and Juranek et al. (2009).
