Description
NCEI Accession 0157368 includes chemical, physical, and profile data collected from the R/V Knorr in the Davis Strait, Labrador Sea, North Atlantic Ocean, North Greenland Sea, and Norwegian Sea from April to October 1981. The data set contains measurements of dissolved inorganic carbon, total alkalinity, partial pressure of carbon dioxide, dissolved oxygen, nutrients, temperature, and salinity. These data were collected by researchers from GEOMAR and the Leibniz Institute for Marine Sciences using CTD and bottle instruments as part of the TTO-NAS_Corrected and Tanhua_Wallace_Revised_DIC_TALK projects.
Use Cases
Calibrating ocean carbon cycle models based on direct measurements of dissolved inorganic carbon and alkalinity.
Analyzing seasonal variability in ocean acidification parameters based on time-series data from a 1981 cruise.
Studying the relationship between physical oceanography (temperature, salinity) and carbon chemistry in subpolar seas.
Validating satellite-derived ocean surface pCO2 estimates using in-situ fugacity of carbon dioxide measurements.
Strengths
Data covers multiple key ocean basins (Davis Strait, Labrador Sea, North Atlantic Ocean, North Greenland Sea, Norwegian Sea) within a single cruise.
Includes a core suite of carbon system variables (DIC, TA, pCO2) alongside complementary physical and nutrient measurements.
Collected by established oceanographic institutions (GEOMAR, Leibniz Institute) using standard instruments (CTD, bottle).
