Dataset Overview | National Centers for Environmental Information (NCEI)

Total dissolved copper, estimates of free Cu2+, ligand concentrations, and conditional stability constants from R/V Knorr KN199-04, KN204-01, subtropical North Atlantic Ocean from 2010-2011 (U.S. GEOTRACES NAT project) (NCEI Accession 0278259)

This dataset contains chemical and physical data collected on R/V Knorr during cruises KN199-04 and KN204-01 in the North Atlantic Ocean on 2013-10-22. These data include depth and trace metal concentration. The instruments used to collect these data include BASi Controlled Growth Mercury Electrode, GO-FLO Teflon Trace Metal Bottle, GeoFish Towed near-Surface Sampler, and Mass Spectrometer. These data were collected by James W. Moffett of University of Southern California 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 2021-05-12.

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

Total dissolved copper and estimates of free Cu2+, ligand concentrations, and conditional stability constants

Dataset Description:
Total dissolved copper and estimates of free Cu2+ and ligand concentrations and conditional stability constants.

Expanded/revised data was served on 5 Nov. 2013.

Please note that data may not be final, pending intercalibration results and further analysis. If you are interested in following changes to US GEOTRACES data, there is an RSS feed available from the GEOTRACES-NAT project page.

Supplemental Information
Acquisition Description:
Samples for total dissolved Cu were acidified in accordance with the standard GEOTRACES protocol using Optima Grade hydrochloric acid.

Samples for speciation determination were processed on board, or were frozen in a -20 freezer for analysis ashore.
Speciation measurements were performed on samples that were titrated with increasing amounts of Cu, and the change in Cu complexation was determined using competitive ligand exchange cathodic stripping voltammetry, as described in Moffett and Dupont (2007).

The raw data were fit to a speciation model using non-linear regression as described in Moffett and Dupont (2007).
Purpose This dataset is available to the public for a wide variety of uses including scientific research and analysis.
