PACKAGE DESCRIPTION: This dataset includes chemical, discrete sample, physical and profile data collected from HUDSON in the Davis Strait, Gulf of St. Lawrence, Labrador Sea and North Atlantic Ocean from 2006-05-24 to 2006-06-08. These data include CHLOROFLUOROCARBON-11 (CFC-11), CHLOROFLUOROCARBON-113 (CFC-113), CHLOROFLUOROCARBON-12 (CFC-12), Carbon tetrachloride (CCL4), DISSOLVED INORGANIC CARBON (DIC), DISSOLVED OXYGEN, HYDROSTATIC PRESSURE, NITRATE, Potential temperature (theta), SALINITY, TOTAL ALKALINITY (TA), WATER TEMPERATURE, methyl chloroform (MC), nitrate + nitrite content (concentration), phosphate and silicate. The instruments used to collect these data include Alkalinity titrator, CTD, Coulometer for DIC measurement and bottle.
These data were collected by Kumiko Azetsu-Scott and Ross Hendry of Bedford Institute of Oceanography as part of the CLIVAR_AR07W_2006 data set. CDIAC associated the following cruise ID(s) with this data set: CLIVAR_AR07W_2006
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.
CITE AS: Azetsu-Scott, Kumiko; Hendry, Ross M. (2013). Dissolved inorganic carbon, alkalinity, temperature, salinity and other variables collected from discrete sample and profile observations using Alkalinity titrator, CTD and other instruments from HUDSON in the Davis Strait, Gulf of St. Lawrence and others from 2006-05-24 to 2006-06-08 (NCEI Accession 0108222).
