Discrete profile measurements of dissolved inorganic carbon (DIC), total alkalinity (TA), temperature, salinity, oxygen, nutrients and other parameters during the M/V Tiglax Seward Line cruises TXS09 and TXF09 (EXPOCODEs: 33A020090503 and 33A020090914) in the Gulf of Alaska, North Pacific Ocean from 2009-05-03 to 2009-09-19 (NCEI Accession 0210032)

This dataset includes chemical data from discrete samples and accompanying physical data from a profiling CTD collected during the USFWS M/V Tiglax Seward Line cruises TXS09 and TXF09 (EXPOCODEs: 33A020090503 and 33A020090914) in the Gulf of Alaska, North Pacific Ocean from 2009-05-03 to 2009-09-19. These data include dissolved inorganic carbon (DIC), total alkalinity (TA), temperature, salinity, oxygen, nutrients (Nitrate, Nitrite, Phosphate, and Silicate) and other parameters. The cruise was funded by the North Pacific Research Board (NPRB), the National Oceanic and Atmospheric Administration (NOAA), the Alaska Ocean Observing System (AOOS), and the Exxon Valdez Oil Spill Trustee Council (EVOSTC). The carbon data were collected and analyzed by personnel at the Ocean Acidification Research Center (OARC) at the University of Alaska Fairbanks (UAF). The CTD operations on the cruise were managed by personnel from the College of Fisheries and Ocean Sciences (CFOS) at UAF. The nutrient data were analyzed by the Whitledge Laboratory at CFOS-UAF. Data files are in .csv format and titled with the ship code (e.g., TX), the season (S = Spring and F = Fall), and the year (e.g., 08-17).
