Partial pressure of carbon dioxide, salinity, temperature and other variables collected from surface underway observations from F.G. Walton Smith coastal cruises in the Atlantic Ocean and Gulf of Mexico in 2018 (NCEI Accession 0173367)
- NOAA Atlantic Oceanographic and Meteorological Laboratory (AOML)PACKAGE DESCRIPTION: This dataset includes surface underway, chemical, meteorological and physical data collected from F.G. Walton Smith in the Gulf of Mexico and North Atlantic Ocean in 2018. These data include air-sea difference of partial pressure of carbon dioxide, partial pressure of carbon dioxide in atmosphere, partial pressure of carbon dioxide in water, barometric pressure, sea surface salinity and temperature. The instruments used to collect these data include barometric pressure sensor, carbon dioxide gas analyzer, shower head chamber equilibrator for autonomous carbon dioxide measurement and thermosalinographs. These data were collected by Frank J. Millero, Ryan Woosley, of Rosenstiel School of Marine and Atmospheric Science and Rik Wanninkhof and Kevin Sullivan of NOAA Atlantic Oceanographic and Meteorological Laboratory. 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.
