Dissolved inorganic carbon (DIC), pH on total scale, total alkalinity, water temperature, salinity and other variables collected from discrete sample and profile observations during the R/Vs Endeavour, CCGS John P. Tully and Parizeau Line P cruises in the Coastal Waters of SE Alaska, Gulf of Alaska and North Pacific Ocean from 1985-02-12 to 2017-02-20 (NCEI Accession 0110260)
PACKAGE DESCRIPTION: This dataset includes discrete sample and profile observations data collected during the R/Vs Endeavour, CCGS John P. Tully and Parizeau Line P cruises in the Coastal Waters of SE Alaska, Gulf of Alaska and North Pacific Ocean from 1985-02-12 to 2017-02-20. These data include dissolved inorganic carbon (DIC), pH on total scale, total alkalinity, temperature, salinity, dissolved nitrite plus nitrate, phosphate and silicate. The instruments used to collect these data include alkalinity titrator, coulometer for DIC measurement, CTD, Niskin bottles, spectrophotometer and other instruments. These data were collected by Lisa A. Miller, Marty Davelaar, Joe Linguanti and Jim Christian of Department of Fisheries and Oceans; Institute of Ocean Sciences as part of the Line_P 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.
