| Summary: | In February 2011, the Ocean Carbon Group at NOAA's Atlantic Oceanographic and Meteorological Laboratory (AOML) installed an instrument to measure CO2 levels in surface water and air on the NOAA Ship Henry B. Bigelow. The Bigelow primarily operates in the North Atlantic Ocean between North Carolina and Maine. NCEI Accession 0162209 includes Surface underway, chemical, meteorological and physical data collected from NOAA Ship R/V Henry B. Bigelow in the North Atlantic Ocean, US North East coast from 2014-03-29 to 2014-11-13. These data include measurements of mole fraction of CO2 in the equilibrator headspace (dry) at equilibrator temperature, mole fraction of CO2 measured in dry outside air, barometric pressure in the equilibrator headspace, barometric pressure, corrected to sea level, water temperature in equilibrator, sea surface temperature, sea surface salinity, fugacity of CO2 in sea water at SST and 100% humidity, and difference between sea water fCO2 and interpolated air fCO2. 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 US DOC; NOAA; OAR; Atlantic Oceanographic and Meteorological Laboratory as part of the Henry B. Bigelow research coastal cruises HB1401-Leg1, HB1401-Leg2, HB1401-Leg3, HB1401-Leg4, HB1401-Leg5, HB1402, HB1403, HB1404, HB1405-Leg1, HB1405-Leg2, HB1405-Leg3, HB1405-Leg4 data set. The cruise Expedition codes (EXPOCODE) are 33HH20140329, 33HH20140411, 33HH20140506, 33HH20140516, 33HH20140527, 33HH20140618, 33HH20140725, 33HH20140805, 33HH20140908, 33HH20140923, 33HH20141007.
