Underway pCO2 measurements aboard R/V G.O. Sars during the 2016 cruises (NCEI Accession 0169195)

INVESTIGATOR:
Ingunn Skjelvan - University of Bergen; Geophysical Institute (GFI)

PACKAGE DESCRIPTION: This dataset includes Surface underway data collected from R/V G.O. Sars in the North Atlantic Ocean, Norwegian Sea and North Sea from 2016-02-20 to 2016-11-30. These data include barometric pressure, partial pressure (or fugacity) of carbon dioxide - atmosphere, partial pressure (or fugacity) of carbon dioxide - water, sea surface salinity and sea surface temperature. The instruments used to collect these data include carbon dioxide (CO2) gas analyzer, shower head chamber equilibrator for autonomous carbon dioxide (CO2) measurement. These data were collected by Ingunn Skjelvan of Uni Research Climate and Geophysical Institute, University of Bergen as part of the SOOP_GO_Sars_20016 data set.
