Dissolved oxygen from sediment cores collected on the R/V Nathaniel B. Palmer cruise NBP1601 to the West Antarctic continental shelf in January of 2016 (NCEI Accession 0278295)
This dataset contains chemical data collected on RVIB Nathaniel B. Palmer during cruise NBP1601 in the South Atlantic Ocean, South Pacific Ocean, and Southern Ocean from 2016-01-15 to 2016-01-29. These data include dissolved Oxygen. The instruments used to collect these data include Multi Corer and Voltammetry Analyzers. These data were collected by John P Christensen of New England Oceanographic Laboratory and David J Burdige of Old Dominion University as part of the "Organic Carbon Oxidation and Iron Remobilization by West Antarctic Shelf Sediments (Antarctic Shelf Sediments)" project. The Biological and Chemical Oceanography Data Management Office (BCO-DMO) submitted these data to NCEI on 2020-06-18.

Supplemental Information | Acquisition Description: Sediment and pore water collection: Short sediment cores were collected using a Bowers & Connelly megacorer, a multiple coring device that can collect ~20-40 cm long sediment cores with undisturbed sediment surfaces. Megacorer cores were either sectioned for solid phase analysis, profiled with polarographic microelectrodes to determine dissolved O2 concentrations, or sectioned in a cold van under N2 for pore water sample extraction. Dissolved oxygen analyses: This was carried out by microprofiling sediment cores in a cold room using voltametric gold-amalgam (Au/Hg) microelectrodes, as described in detail elsewhere (Brendel and Luther, 1995; Luther et al., 1998; Luther et al., 2008). An Analytical Instrument Systems model DLK-100 voltammetric analyzer was used for all measurements, with profiling carried out using an AIS computer-controlled automated micromanipulator. Oxygen was determined by linear-sweep voltammetry (voltage range: -0.1 to -1.8 V, scan rate: 200 mV/s), and quantified based on the peak height at roughly -0.3 V. Electrodes were calibrated using a two-point calibration curve with O2 saturated bottom water and the electrode response in the deeper O2-free zone of the sediments (Cai and Sayles, 1996). Five scans were carried out at each depth, with the last three scans typically averaged for concentration determinations. |
