This dataset includes discrete profile measurements of dissolved inorganic carbon (DIC), total alkalinity, water temperature, salinity, dissolved oxygen, nutrients and other hydrographic and chemical data collected from discrete samples and profile observations during the CCGS Louis S. St-Laurent Joint Ocean Ice Study (JOIS-12) cruise (EXPOCODE 18SN20120802) in the Arctic Ocean from 2012-08-02 to 2012-08-30. The Joint Ocean Ice Study (JOIS) in 2012 is an important contribution from Fisheries and Oceans Canada to international Arctic climate research programs. Primarily, it involves the collaboration of Fisheries and Oceans Canada researchers with colleagues in the USA from Woods Hole Oceanographic Institution (WHOI). The scientists from WHOI lead the Beaufort Gyre Exploration Project (BGEP) which forms part of the Arctic Observing Network (AON).
