Sea surface and atmospheric carbon dioxide (CO2) measurements in the Atlantic Ocean during the Ship of Opportunity (SOOP) UK to Caribbean lines onboard the MV Benguela Stream in 2017 (NCEI Accession 0174135)
PACKAGE DESCRIPTION: This dataset includes surface underway, chemical, meteorological and physical data collected from Ship of Opportunity (SOOP) MV Benguela Stream in the North Atlantic Ocean from 2017-01-21 to 2017-10-19. These data include partial pressure of carbon dioxide (pCO2) - water, pCO2 - air, air-sea difference of pCO2, barometric pressure, dissolved oxygen, nutrients, sea surface salinity and temperature. The instruments used to collect these data include barometric pressure sensor and carbon dioxide gas analyzer. These data were collected by Dr. Ute Schuster of University of Exeter.
