Dissolved inorganic carbon, total alkalinity, pH and other variables collected from profile and discrete sample observations using CTD, Niskin bottle, and other instruments from R/V Fairweather and R/V Point Sur in the U.S. West Coast California Current System during the 2013 West Coast Ocean Acidi

This cruise represents the third dedicated West Coast Ocean Acidification cruise (Expocode:317W20130803, Cruise ID: WCOA2013), which took place August 3-10, 2013 aboard the R/V Fairweather and August 21 to 29, 2013 aboard the R/V Pt. Sur. Seventy-six stations were occupied from northern Washington to California along ten transect lines. At all stations, CTD casts were conducted, and discrete water samples were collected in Niskin bottles. The cruise was designed to obtain a synoptic snapshot of key carbon, physical, and biogeochemical parameters as they relate to ocean acidification (OA) in the coastal realm. During the cruise, some of the same transect lines were occupied as during the 2007, 2011, and 2012 West Coast Carbon cruises, as well as many CalCOFI stations. This effort was conducted in support of the coastal monitoring and research objectives of the NOAA Ocean Acidification Program (OAP). Leg 1 was surveyed onboard R/V Fairweather from August 3 to 10, 2013. The original cruise names for Leg 1 are: WCOA-13, CC1-13-FA. Leg 2 was surveyed onboard R/V Point Sur from August 21 to 29, 2013. The original cruise names for Leg 2 are: WCOA-13, CC2-13-PS.
