Dissolved inorganic carbon (DIC), total alkalinity, pH on sea water scale, temperature, salinity and other variables collected from discrete sample and profile observations during the R/V Roger Revelle cruise CD139, CLIVAR I09N_2007 (EXPOCODE 33RR20070322) in the Indian Ocean from 2007-03-22 to 2007-05-01 (NCEI Accession 0110791)

This dataset includes discrete profile measurements of dissolved inorganic carbon (DIC), total alkalinity, pH on sea water scale, temperature, salinity, dissolved oxygen, nutrients, chlorofluorocarbons (CFC-11, CFC-12, CFC113), dissolved organic carbon (DOC), tritium and helium obtained during the R/V Roger Revelle cruise CD139, CLIVAR I09N_2007 (EXPOCODE 33RR20070322) in the Indian Ocean from 2007-03-22 to 2007-05-01. These data were collected by Christopher L. Sabine and Richard A. Feely of NOAA Pacific Marine Environmental Laboratory (PMEL) and Frank J. Millero of Rosenstiel School of Marine and Atmospheric Science (RSMAS) as part of the CLIVAR I09N_2007 dataset. 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.
