Methods & Sampling

Location: SUSTAIN wind-wave Tank, University of Miami

See Supplemental files section for "Noble Gas Ratios of Saturation Anomalies" data.

Methodology:

Noble gas ratios are measured using a Gas equilibator Inlet Mass Spectrometer (GEMS) according to Manning et al. (2016). O2/Ar ratios are measured using an Equilibator Inlet Mass Spectrometer (EIMS), similar to that of Cassar et al 2009 but with an equilibator system as in the GEMS. O2 concentrations are measured by an optode calibrated by Winkler. All of those data streams are combined to calculate noble gas concentrations.

Sampling and analytical procedures:

A full description of the sample collection and analysis is in Stanley et al., “Gas Fluxes and Steady State Saturation Anomalies at Very High Wind Speeds“ Submitted to JGR-Oceans in Dec. 2021 (Stanley et al., 2022). Relevant paragraphs from the methodology can be found in the Supplemental Files section of this dataset page.

Data Processing Description

See Supplemental files section for "Noble Gas Ratios of Saturation Anomalies" data.

Codes written in matlab were used to convert the raw mass spectrometer data into noble gas ratios. The ratios were then calibrated using measurements in air taken before and after each experiment. Similar calibrations were done for the O2/Ar ratios. Optode data was calibrated with Winkler Samples measured periodically through the experiment. As described above, the noble gas ratios, O2/Ar ratios and optode concentrations were combined to calculate noble gas calculations – all those calculations were done in Matlab. Then the discrete copper tube samples were used as a final calibration of the noble gas concentrations.

BCO-DMO Data Manager Processing Notes:
* File ContinuousNobleGasData.txt imported into the BCO-DMO data system.
* Parameters (column names) renamed to comply with BCO-DMO naming conventions. See https://www.bco-dmo.org/page/bco-dmo-data-processing-conventions
* DateTime (UTC) column added in ISO 8601 format yyyy-mm-ddTHH:MM:SSZ.
* Sampling and Analytical methods summary saved as a pdf from the BCO-DMO metadata form so the formula can be read. The methodology section on this page is plain-text only.
* NGRatiosofSatAnom.txt file extension changed to csv and attached as a Supplemental File.
