PACKAGE DESCRIPTION: This dataset includes surface underway, chemical, meteorological and physical data collected during NOAA Ship Ronald H. Brown cruises in the Coastal Waters of Florida, Atlantic Ocean and Gulf of Mexico from 2012-02-15 to 2012-09-05. These data include partial pressure (or fugacity) of carbon dioxide - atmosphere, partial pressure (or fugacity) of carbon dioxide - water, sea surface temperature and sea surface salinity. The instruments used to collect these data include Carbon dioxide (CO2) gas analyzer and Shower head chamber equilibrator for autonomous carbon dioxide (CO2) measurement. These data were collected by Rik Wanninkhof and Denis Pierrot of NOAA Atlantic Oceanographic and Meteorological Laboratory.
