PACKAGE DESCRIPTION: This dataset includes surface underway, chemical, meteorological and physical data collected from NOAA Ship Ronald H. Brown cruises in the Pacific Ocean and Arctic Ocean from 2015-01-15 to 2015-12-18. These data include partial pressure (or fugacity) of carbon dioxide - atmosphere, partial pressure (or fugacity) of carbon dioxide - water, sea surface salinity and sea surface temperature. The instruments used to collect these data include Carbon dioxide (CO2) gas analyzer. These data were collected by Rik Wanninkhof, Robert Castle and Denis Pierrot of NOAA Atlantic Oceanographic and Meteorological Laboratory as part of the VOS_R/V_Ronald_Brown_2015 data set.
