Dataset Overview | National Centers for Environmental Information (NCEI)

Dissolved Ga and Ba from surface tows from R/V Knorr cruises KN199-04, KN199-05, and KN204-01 in the Subtropical northern Atlantic Ocean from 2010-2011 (U.S. GEOTRACES NAT project) (NCEI Accession 0278627)

Graphic not available.

This dataset contains chemical and physical data collected on R/V Knorr during cruises KN199-04, KN199-05, and KN204-01 from 2010-10-17 to 2011-12-09. These data include depth and trace metal concentration. The instruments used to collect these data include GeoFish Towed near-Surface Sampler and Inductively Coupled Plasma Mass Spectrometer. These data were collected by Alan M. Shiller of University of Southern Mississippi as part of the "U.S. GEOTRACES North Atlantic Transect (U.S. GEOTRACES NAT)" project and "U.S. GEOTRACES (U.S. GEOTRACES)" program. The Biological and Chemical Oceanography Data Management Office (BCO-DMO) submitted these data to NCEI on 2021-01-08.

The following is the text of the dataset description provided by BCO-DMO:

Dissolved Ga and Ba from surface tows from GT10 and GT11 cruises.

Dataset Description:
Lab-based measurements of dissolved Gallium (Ga) and Barium (Ba) from surface tows from the 2010 and 2011 US GEOTRACES cruises (GT10 and GT11).

STATUS NOTE: These data were significantly updated on 30 August 2016. A volume correction had not been applied to the previous version, and thus all of the original values needed to be multiplied by 0.9805. This correction has been applied in the 30 August version, now available online. There were also some samples that were re-analyzed for Ba with the values revised accordingly. Additionally, the PIs withdrew the Pb data (in the original version) because higher quality Pb data are already available from these cruises.

Please note that some US GEOTRACES data may not be final, pending intercalibration results and further analysis. If you are interested in following changes to US GEOTRACES NAT data, there is an RSS feed available via the BCO-DMO US GEOTRACES project page (scroll down and expand the "Datasets" section).

Supplemental Information	Acquisition Description: The samples were collected for trace metal determinations at various stations from the RV Knorr using a custom-built US GEOTRACES trace metal clean rosette consisting of an epoxy painted Al rosette frame containing 24x12 L GO-FLO bottles (Cutter and Bruland, 2012). Immediately after the rosette was recovered, the tops of the GO-FLO bottles were covered with plastic bags and the bottles were removed from the frame and carried into the US GEOTRACES clean van for sub-sampling. The GO-FLO bottles were pressurized to 10 psi using 0.2 um-filtered compressed air and samples were filtered through 0.2 um Acropak or membrane filters. All sub-sampling was undertaken in the clean van using rigorous trace metal protocols. Additional surface water samples were collected from a clean underway sampling system (the "GeoFish") and similarly filtered. This dataset contains the surface samples. To see the bottle data, refer to the GT10-11 - GaBa_bottles dataset (see Related Datasets). Ga and Ba were determined by isotope dilution ICP-MS using a ThermoFisher Element 2 operated in low resolution. For Ga, samples were concentrated using Mg(OH)₂ co-precipitation (Shiller & Bairamadgi, 2006; Zurbrick et al., 2012) while Ba was determined following 20-fold dilution in dilute nitric acid (Shim et al., 2012).
