Partial pressure of carbon dioxide, temperature and other variables collected from surface underway observations around Iceland during R/V Bjarni Saemundsson cruises in the Irminger Sea, Iceland Sea and North Atlantic in from 2006-05-14 to 2019-10-21 (NCEI Accession 0190200)
PACKAGE DESCRIPTION: This dataset includes surface underway chemical, meteorological and physical data collected from R/V Bjarni Saemundsson cruises in the Irminger Sea, Iceland Sea and North Atlantic from 2006-05-14 to 2019-10-21. These data include measurements of sea surface temperature (SST), equilibrator temperature (TEQ), equilibrator pressure (PEQ), mole fraction of carbon dioxide (xCO2) in dry air at TEQ, pCO2 at TEQ (PCO2TEQ). The instruments used to collect these data include carbon dioxide (CO2) gas analyzer and shower head chamber equilibrator for autonomous CO2 measurement.
