Partial pressure (or fugacity) of carbon dioxide, salinity and SEA SURFACE TEMPERATURE collected from underway - surface observations using Carbon dioxide (CO2) gas analyzer, Shower head chamber equilibrator for autonomous carbon dioxide (CO2) measurement and other instruments from the HEALY in the

NODC Accession 0083197 includes chemical, physical and underway - surface data collected from HEALY in the Arctic Ocean, Beaufort Sea, Bering Sea, Coastal Waters of SE Alaska, Gulf of Alaska, Hawaiian Islands Humpback Whale National Marine Sanctuary, North Pacific Ocean and Northwest Passage from 2011-05-17 to 2012-10-26 and retrieved during cruise CGC Healy Lines. These data include Partial pressure (or fugacity) of carbon dioxide, SALINITY and SEA SURFACE TEMPERATURE. 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 Taro Takahashi and S. Sutherland of Columbia University; Lamont-Doherty Earth Observatory and Colm Sweeney of University of Colorado At Boulder; Cooperative Institute for Research In Environmental Sciences as part of the CGC Healy Lines data set.

The Global Volunteer Observing Ship (VOS) Program is coordinated by the UNESCO International Ocean Carbon Coordination Project (IOCCP). International groups from 14 countries have been outfitting research ships and commercial vessels with automated CO2 sampling equipment to analyze the carbon exchange between the ocean and atmosphere.
