Abstract:
This dataset comprises Radium (Ra), Barium (Ba) and δ18O tracers in addition to chemical constituents (Dissolved Inorganic Carbon (DIC) and Total Alkalinity (AT)) collected during 2015 Canadian GEOTRACES expedition (GN02/GN03) throughout the Canadian Arctic Archipelago aboard the CCGS Amundsen. Included within the dataset are the latitude and longitudes of sampling stations, as well as the sampled depths and the associated basic hydrographic data (T and SP). For every data point, in addition to date and time of collection, the accompanying event, cast and bottle number are recorded as well as GEOTRACES Event ID number. The compilation of this dataset was supported by the Canadian GEOTRACES program as part of the NSERC-CCAR, the U.S. GEOTRACES via NSF Chemical Oceanography (grant no. OCE-1458305), and the DAAD, MOPGA-GRI (grant no.57429828).
