Description

Carbonate chemistry and isotopes from nine M/S Columbus Waikato cruises between New Zealand and Long Beach, CA in the Pacific Basin from 2004-2006. This dataset includes dissolved inorganic carbon (DIC), and del13C-DIC.

Methods & Sampling

Dataset acquisition description

Shipboard Sample Collection Methods: Samples were collected in pre-washed and baked 250 ml ground glass stoppered bottles that were poisoned with 100 ul of a saturated HgCl2 solution. The stored sealed samples were returned to the Stable Isotope Laboratory at the University of Washington for extraction and measurement.

Laboratory Methods: CO2 was extracted from the DIC seawater samples using a modification of the helium stripping technique described in Quay and Stutsman (2003). The del13C is measured on a Thermo Finnigan MAT 253 mass spectrometer.

Data Processing Description

Dataset Processing Description

Data are only reported for samples that meet quality control standards (any with problems in the laboratory extraction and measurement process have been omitted in the data spreadsheet). Blank cells have been replaced with nd (no data).

BCO-DMO Data Processing:
- re-formatted time to HHMM;
- modified parameter names to conformw ith BCO-DMO naming conventions (replaced hyphens with underscores);
- added ISO_DateTime_UTC using original date and time fields.
