Electrochemical data from sediments collected on R/V Savannah cruise SAV-15-18 at the Cape Lookout Continental Shelf and Slope during July 2015 (NCEI Accession 0278768)

This dataset contains chemical and physical data collected on R/V Savannah during cruise SAV-15-18 in the North Atlantic Ocean from 2015-07-08 to 2015-07-20. These data include Fe, Mn, Sulfur, and dissolved Oxygen. The instruments used to collect these data include Multi Corer and Voltammetry Analyzers. These data were collected by Martial Taillefert of Georgia Institute of Technology as part of the "Source, Composition, and Stability of Soluble Iron Fluxing from Continental Margin Sediments (Soluble Fe Fluxing)" project. The Biological and Chemical Oceanography Data Management Office (BCO-DMO) submitted these data to NCEI on 2020-01-17.

Electrochemical data

Dataset Description:
Acquisition Description:
Sediments were collected and profiled immediately with voltammetric Hg/Au microelectrodes deployed on a computer-controlled micromanipulator (Beckler et al., 2016).

Sediment cores were obtained by a MC-800 multi-corer and profiled within 30 minutes with voltammetric Hg/Au microelectrodes deployed on a computer-controlled micromanipulator. O₂₍ₐq₎, Mn(II), Fe(II), Org-Fe(III), FeS₍ₐq₎, and SH2S were measured by voltammetry using non-invasive mercury/gold (Hg/Au) microelectrodes (Luther et al., 2008) in intact sediment cores. Org-Fe(III) and FeS(aq) cannot be quantified by these methods and are reported in current intensities.

Problem report: Some of the data are missing because pore water volumes were too low to make all the measurements.
