Dissolved inorganic carbon (DIC), total alkalinity, pH on total scale, 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-11) cruise (EXPOCODE 18SN20110721) in the Arctic Ocean from 2011-07-21 to 2011-08-18 (NCEI Accession 0232544)

This dataset includes discrete profile measurements of dissolved inorganic carbon (DIC), total alkalinity, pH on total scale, 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-11) cruise (EXPOCODE 18SN20110721) in the Arctic Ocean from 2011-07-21 to 2011-08-18. The 2011 Joint Ocean Ice Study (JOIS) involved the collaboration of Fisheries and Oceans Canada researchers with colleagues primarily from the U.S.A and Japan. This program forms an important Canadian contribution to international climate research programs and is primarily a collaboration with the Beaufort Gyre Exploration Project (BGEP) based at Woods Hole Oceanographic Institution. There are also strong links with Japanese scientists via the Pan-Arctic Climate Investigation (PACI), a collaboration with Japan Agency for Marine-Earth Science and Technology (JAMSTEC), and with Tokyo University of Marine Science and Technology. In 2011 JOIS also included ancillary programs carried out by researchers from: the International Arctic Research Center (IARC) in Fairbanks Alaska; Kitami Institute of Technology (KIT), Japan; and University of Akron, Akron Ohio.
