This dataset includes Surface underway, chemical, meteorological and physical data collected from NOAA Ship MILLER FREEMAN in the Bering Sea, Coastal Waters of SE Alaska, Cordell Bank National Marine Sanctuary, Gulf of Alaska, Gulf of the Farallones National Marine Sanctuary, Monterey Bay National Marine Sanctuary, North Pacific Ocean and Olympic Coast National Marine Sanctuary from 2009-05-16 to 2010-10-08. These data include AIR-SEA DIFFERENCE - PARTIAL PRESSURE (OR FUGACITY) OF CARBON DIOXIDE, BAROMETRIC PRESSURE, Partial pressure (or fugacity) of carbon dioxide - atmosphere, Partial pressure (or fugacity) of carbon dioxide - water, 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 Richard A. Feely and Cathy Cosca of US DOC; NOAA; OAR; Pacific Marine Environmental Laboratory as part of NOAA Ship Miller Freeman Coastal Underway Measurements data set. CDIAC assigned the following cruise ID(s) to this data set: MF0902_L1, MF0902_L2, MF0902_L3, MF0902_L4, MF0903_L3, MF0904_L2, MF0904_L3, MF1001_L1, MF1001_L2, MF1001_L3, MF1001_T, MF1002_L1, MF1002_L2, MF1003_L2, MF1004, MF1005_L1, MF1005_L2 and MF1006. The Global Coastal Carbon Data Project data includes the bottle (discrete) and surface (underway) carbon-related measurements from coastal research cruises, the data from time series cruises and coastal moorings. The coastal regions data are very important for the understanding of carbon cycle on the continental margins.
