PACKAGE DESCRIPTION: This dataset includes chemical, discrete sample, physical and profile data collected from KNORR in the Davis Strait, Labrador Sea, North Atlantic Ocean, North Greenland Sea and Norwegian Sea from 1981-04-01 to 1981-10-19. These data include DISSOLVED INORGANIC CARBON (DIC), DISSOLVED OXYGEN, NITRATE, Partial pressure (or fugacity) of carbon dioxide - water, Potential temperature (theta), SALINITY, SIGMA-T, TOTAL ALKALINITY (TA), WATER TEMPERATURE, phosphate and silicate. The instruments used to collect these data include CTD and bottle.
These data were collected by Douglas Wallace of GEOMAR Helmholtz Centre for Ocean Research Kiel and Toste Tanhua of Leibniz Institut Fur Meereswissenschaften as part of the TTO-NAS_Corrected and Tanhua_Wallace_Revised_DIC_TALK data set. CDIAC associated the following cruise ID(s) with this data set: TTO-NAS
CITE AS: Tanhua, Toste; Wallace, Douglas W. R. (2016). Partial pressure (or fugacity) of carbon dioxide, dissolved inorganic carbon, alkalinity, temperature, salinity and other variables collected from discrete sample and profile observations using CTD, bottle and other instruments from KNORR in the Davis Strait, Labrador Sea and others from 1981-04-01 to 1981-10-19 (NCEI Accession 0157368).

These files contain dissolved inorganic carbon (DIC) and total alkalinity data collected during the Transient Tracer in the Ocean, North Atlantic Study (TTO-NAS) in 1981 The data have been adjusted based on comparisons with modern results as described by Tanhua and Wallace (2005). In using these revised data it should be considered that alternative adjustments to the important TTO data set may well be recommended in the future. |
