Discrete measurement of Carbon Dioxide, Hydrographic, and Chemical Data and surface underway measurements of partial pressure of CO2 during the R/V Meteor cruise 68/3 in the tropical Atlantic Ocean from 2006-07-12 to 2006-08-06 (NCEI Accession 0109917)

This dataset includes chemical, discrete sample, physical and profile data collected from METEOR in the North Atlantic Ocean from 2006-07-12 to 2006-08-06 and retrieved during cruise MT68_3_2006. These data include ALKALINITY, CHLOROFLUOROCARBON-11 (CFC-11), CHLOROFLUOROCARBON-12 (CFC-12), DISSOLVED INORGANIC CARBON, DISSOLVED OXYGEN, HYDROSTATIC PRESSURE, NITRATE, NITRITE, PHOSPHATE, SALINITY, SILICATE, SULFUR HEXAFLUORIDE (SF6), WATER TEMPERATURE and nitrous oxide and and surface underway measurements of partial pressure of CO2. The instruments used to collect these data include Alkalinity titrator, CTD, Coulometer for DIC measurement and bottle. These data were collected by Arne Körtzinger, Tobias Steinhoff, and Toste Tanhua of GEOMAR Helmholtz Centre for Ocean Research Kiel, Kiel, Germany as part of the MT68_3_2006 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.
