The Ocean Archive System searches our original datasets as they were submitted to us, not individual points or profiles. If you want to search and retrieve ocean profiles in a common format, or objectively analyzed fields, your better option may be to use one of our project applications. See: Access Data

| Title: | Nutrients, cobalt, dissolved iron, and dissolved manganese from trace metal bottles from R/V Knorr cruise KN192-05 in the South Atlantic subtropical gyre and Benguela upwelling region in 2007 (CoFeMUG project) (NCEI Accession 0277924) |
| Abstract: | This dataset contains chemical and physical data collected on R/V Knorr during cruise KN192-05 in the South Atlantic Ocean from 2007-11-18 to 2007-12-11. These data include Ammonium, Nitrite, SiOH_4, depth, nitrate plus nitrite, reactive phosphorus (PO4), and trace metal concentration. The instruments used to collect these data include Metrohm 663 VA Stand mercury electrode, Nutrient Autoanalyzer, Trace Metal Bottle, and Voltammetry Analyzers. These data were collected by Mak A. Saito of Woods Hole Oceanographic Institution as part of the "Cobalt, Iron and Micro-organisms from the Upwelling zone to the Gyre (CoFeMUG)" project and "Ocean Carbon and Biogeochemistry (OCB)" and "U.S. GEOTRACES (U.S. GEOTRACES)" programs. The Biological and Chemical Oceanography Data Management Office (BCO-DMO) submitted these data to NCEI on 2020-03-25. The following is the text of the dataset description provided by BCO-DMO: Analysis of nutrients, Cobalt (total and labile), dissolved Iron, and dissolved Manganese from TM bottle samples. Dataset Description: Analysis of nutrients, Cobalt (total and labile), dissolved Iron, and dissolved Manganese of water samples drawn from Trace Metal Rosette (TMR) bottle casts.

| Supplementary information: | Acquisition Description: Three transects were sampled using the Trace Metal Rosette (TMR) on the CoFeMUG cruise aboard R/V Knorr in 2007. Refer to Noble et al. (2012) for detailed information on acquisition and processing. Nutrient Analyses : Technicon AutoAnalyzer II components were used to measure phophate and ammonium. Alpkem rapid flow analyzer (RFA) 300 components were used to measure silicic acid, nitrate+nitrite, and nitrite. Cobalt Analyses : Total dissolved and labile cobalt concentrations were determined using cathodic stripping voltammetry, previously described by Saito and Moffet (2001) and Saito et al. (2004). Measurements were made using Eco-Chemie uAutolab-III systems connected to Metrohm 663 VA Stands with hanging mercury drop electrodes and Teflon sampling cups. Iron and Manganese Analyses : Total dissolved iron and manganese concentrations were measured using inductively coupled plasma mass spectrometry (ICP-MS). SAFe seawater intercalibration standards were analyzed at the beginning of each analysis day with iron concentrations of 0.96 ± 0.095 nmol L-1 for D2 and 0.125 ± 0.046 nmol L-1 for S1 (n = 10), which are within the reported ranges of 0.91 + 0.17 nmol L-1 and 0.097 + 0.043 nmol L-1 (Johnson et al. 2007). |
