This NCEI Accession includes discrete profile measurements of dissolved inorganic carbon (DIC), total alkalinity, temperature, salinity, oxygen and nutrients measured during NOAA Ship Ronald H. Brown cruise RB1504 (EXPOCODE 33RO20150713) in the the Gulf of Alaska from 2015-07-13 to 2015-07-31. The cruise was funded by the National Oceanic and Atmospheric Administration (NOAA) Ocean Acidification Program (OAP). The carbon, oxygen, and nutrient data were collected an analyzed by members at the Ocean Acidification Research Center (OARC) at the University of Alaska Fairbanks (UAF). The CTD operations on the cruise were managed by personnel from UA with assistance from members of the Pacifica Marine Environmental Laboratory (PMEL) and the ship's crew.
