Total organic sulfur (TOS) collected from Niskin bottle samples on R/V Knorr cruise KN210-04 in the Western Atlantic Ocean between Uruguay and Barbados from March to May 2013 (Deep Atlantic DOM project) (NCEI Accession 0277290)
This dataset contains chemical data collected on R/V Knorr during cruise KN210-04 in the North Atlantic Ocean and South Atlantic Ocean from 2013-03-27 to 2013-05-04. These data include Sulfur and depth. The instruments used to collect these data include Ion Chromatograph and Niskin bottle. These data were collected by Elizabeth Kujawinski and Krista Longnecker of Woods Hole Oceanographic Institution as part of the "Dissolved Organic Matter Composition in the Deep Atlantic Ocean (Deep Atlantic DOM)" project and "Ocean Carbon and Biogeochemistry (OCB)" program. The Biological and Chemical Oceanography Data Management Office (BCO-DMO) submitted these data to NCEI on 2023-01-23.

Supplemental Information | Acquisition Description: Whole seawater samples for obtaining the concentration of total organic sulfur (TOS) were collected directly from the Niskin bottles into combusted 40 mL glass vials. The vials were stored frozen (-20°C) until analysis on land. TOS was determined as described in Cutter et al. In brief, a sample is pumped through three ion exchange cartridges connected in series, a 1 mL Ba (Dionex OnGuard II #057093) to remove most of the sulfate, then through a 2.5 mL Ag (Dionex OnGuard II Ag #057090) to remove chloride, and finally through a 1 mL cartridge packed with BioRad AG 4x4 resin (#143-3341) to remove the remaining sulfate. The resulting sample is then analyzed via ion chromatography to quantify remaining sulfate. Total sulfur is quantitatively converted to H 2 S by via reductive pyrolysis in pure hydrogen gas and quantified by gas chromatography/flame photometric detection using the trapping /detection system of Radford-Knoery and Cutter. Total organic sulfur is calculated as the difference between total sulfur and residual sulfate. Each step of this analysis has an error attached. The units for TOS are nM; when provided, TOS_sd is the standard deviation of the average for replicate samples. Precision was >10% RSD at/above 200 nM S and the detection limit was 26 nM S. |
