This dataset includes discrete profile data collected during the USCCG Healy cruise HLY1502 (EXPOCODE 33HQ20150809) in the Arctic Ocean, Bering Sea, and Chukchi Sea from 2015-08-09 to 2015-10-13. These data include dissolved inorganic carbon, pH, total alkalinity, temperature, salinity, dissolved oxygen, nutrients, chlorofluorocarbons (CFC-11, CFC-12, CFC113), pH on seawater scale, measured at 25 deg.C, methane (CH4), carbon 13 (C13) and sulfur hexafluoride (SF6). The International CLIVAR Global Ocean Carbon and Repeat Hydrography Program carries out a systematic and global re-occupation of select WOCE/JGOFS hydrographic sections to quantify changes in storage and transport of heat, fresh water, carbon dioxide (CO2), and related parameters.

This dataset includes hydrographic and chemical data collected from discrete samples and profile observations from United States Coast Guard Cutter (USCGC) Healy cruise HLY1702 (EXPOCODE 33HQ20170826) in the Bering and Chukchi Sea along transect lines in the Distributed Biological Observatory (DBO) areas DB01, 03, 04, and 05 from 2017-08-26 to 2017-09-15. These data include water temperature, salinity, dissolved inorganic carbon (DIC), total alkalinity (TA), dissolved oxygen, and nutrients (nitrate, nitrite, phosphate, silicate, and ammonium). The cruise was funded by the National Oceanic and Atmospheric Administration (NOAA) Arctic Research Program (ARP) and supported by numerous agencies and institutions including the National Science Foundation (NSF). The carbon data were collected at sea and run using equipment from the Ocean Acidification Research Center (OARC) at the University of Alaska Fairbanks (UAF). Jessica Cross was funded by NOAA's Arctic Research Program and Natalie Monacci was funded by the Cooperative Institute for Alaska Research and the Alaska Ocean Observing System. The CTD operations on the cruise were managed by personnel from the Woods Hole Oceanographic Research Institute (WHOI). Dissolved Oxygen and nutrient data were collected by by personnel from the University of Washington Joint Institute for the Study of the Atmosphere (JISAO). Calvin Mordy was funded by the Ecosystems and Fisheries-Oceanography Coordinated Investigations (EcoFOCI) Program and NOAA's ARP. Phyllis Stabeno is co-Principal Investigator of the EcoFOCI program.

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-14) cruise (EXPOCODE 18SN20140921) in the Arctic Ocean, Beaufort Sea from 2014-09-21 to 2014-10-17. The Joint Ocean Ice Study (JOIS) in 2014 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) and the Beaufort Gyre Observing System (BGOS) which forms part of the Arctic Observing Network (AON).

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.

This dataset includes chemical, discrete sample, physical and profile data collected from HEALY in the Arctic Ocean, Beaufort Sea and Bering Sea from 2012-10-05 to 2012-10-25. These data include DISSOLVED INORGANIC CARBON (DIC), HYDROSTATIC PRESSURE, SALINITY, TOTAL ALKALINITY (TA) and WATER TEMPERATURE. The instruments used to collect these data include CTD and bottle. These data were collected by Jeremy T. Mathis of NOAA Pacific Marine Environmental Laboratory (PMEL) and Natalie M. Monacci of University of Alaska - Fairbanks (UAF) as part of the CLIVAR_HLY1203 dataset.
