Dissolved Inorganic Carbon (DIC), Total Alkalinity, Oxygen and other Hydrographic and Chemical Data Obtained During R/V Polarstern Cruise ARKXXVII/1 (EXPOCODE 06AQ20120614) along the CLIVAR Repeat Section 75N in the North Atlantic Ocean from 2012-06-14 to 2012-07-15 (NCEI Accession 0162432)
- GEOMAR Helmholtz Centre for Ocean Research Kiel, Kiel, GermanyPACKAGE DESCRIPTION: This dataset includes discrete bottle measurements of Dissolved Inorganic Carbon (DIC), Total Alkalinity, temperature, salinity, oxygen and CFCs from R/V Polarstern Cruise ARKXXVII/1 (EXPOCODE 06AQ20120614) in the North Atlantic Ocean, Section 75N, from 2012-06-14 to 2012-07-15. The R/V Polarstern ARKXXVII/1 cruise is a part of the CLIVAR/GO-SHIP Repeat Sections observations from the research ships along the section 75N. This work was supported by the Deutsche Forschungsgemeinschaft (DFG) in the framework of the priority program Antarctic Research with comparative investigations in Arctic ice area by a grant to T. Tanhua and M. Hoppema: Carbon and 25 transient tracers dynamics: A bi-polar view on Southern Ocean eddies and the changing Arctic Ocean (TA 317/5, HO 4680/1)
