Total alkalinity, pH on total scale, water temperature, salinity and dissolved oxygen concentration collected from discrete sample and profile observations during the United States Coast Guard Cutter (USCGC) Healy cruise HLY1103 (EXPOCODE 33HQ20111003) in the Arctic Ocean, Beaufort Sea and Northwestern Passages from 2011-10-03 to 2011-10-27 (NCEI Accession 0157310)
PACKAGE DESCRIPTION: This dataset includes hydrographic and chemical data collected from discrete samples and profile observations from United States Coast Guard Cutter (USCGC) Healy cruise HLY1103 (EXPOCODE 33HQ20111003) in the Arctic Ocean, Beaufort Sea and Northwestern Passages from 2011-10-03 to 2011-10-27. These data include Total alkalinity, pH on total scale, water temperature, salinity and dissolved oxygen concentration. The instruments used to collect these data include CTD and Niskin bottles. These data were collected by Jeremy Mathis of US DOC; NOAA; OAR; Pacific Marine Environmental Laboratory and Natalie Monacci of University of Alaska - Fairbanks as part of the CLIVAR_HLY1103 data set. 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.
