D13C of Dissolved Inorganic Carbon (DIC) measured on bottle cast samples from Leg 2 (Hilo, HI to Papeete, French Polynesia) of the US GEOTRACES Pacific Meridional Transect (PMT) cruise (GP15, RR1815) on R/V Roger Revelle from October to November 2018 (NCEI Accession 0278535)
This dataset contains physical data collected on R/V Roger Revelle during cruise RR1815 in the North Pacific Ocean and South Pacific Ocean from 2018-10-25 to 2018-11-23. These data include water pressure. The instruments used to collect these data include Isotope-ratio Mass Spectrometer and Niskin bottle. These data were collected by Paul Quay of University of Washington as part of the "Decadal trends in oceanic anthropogenic CO2 from the CLIVAR and GO-SHIP d13C datasets and in an ocean biogeochemistry model (CO2 Decadal Trends)" and "US GEOTRACES Pacific Meridional Transect (U.S. GEOTRACES PMT)" projects and "U.S. GEOTRACES (U.S. GEOTRACES)" program. The Biological and Chemical Oceanography Data Management Office (BCO-DMO) submitted these data to NCEI on 2022-06-27.
The following is the text of the dataset description provided by BCO-DMO:
GP15 d13C-DIC Leg 2
Dataset Description:
Acquisition Description:
Niskin seawater samples were collected in 250 ml bottles and poisoned with 100 µl of mercuric chloride. In the lab, approximately 100 ml was transferred from the bottle to a bubbler attached to a high vacuum line. Samples were acidified with 1 ml of 50% phosphoric acid before stripping with He gas at 200 ml min⁻¹. CO₂ gas was collected cryogenically in a liquid nitrogen cold trap after removal of water vapor. CO₂ yield was calculated manometrically (1σ = 5 µmol kg⁻¹) before transfer to a vacuum flask for isotopic analysis.
