Methods & Sampling

In situ pump profiler cast refers to profiling with a pump profiler for O₂ and H₂S using solid state gold-amalgam electrodes for voltammetry (Luther et al, 2008; Analytical Instrument Systems DLK-60). Water was pumped aboard to make measurements on discrete samples for Mn and Fe speciation as well. See Hudson et al (2019) for more information.

H₂S
Sedimentary porewater H₂S methods (UV-Vis spectrophotometry) followed Luther et al. (2011).

Data Processing Description

Data Processing:
NM is used to indicate sensor not available or no measurement.

BCO-DMO Processing:
- converted date field to YYYY-MM-DD format;
- added date/time column in ISO8601 format (UTC/GMT);
- converted latitude and longitude to decimal degrees from degrees and decimal minutes.

Supplied Description:

Instrument Type

Generic Name: Automatic titrator

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/LAB12/

Generic Description:

Instruments that incrementally add quantified aliquots of a reagent to a sample until the end-point of a chemical reaction is reached.

CO2 Analyzer

Supplied Name: infrared CO2 analyzer (AS-C3, Apollo Scitech)

Supplied Description:

Instrument Type

Generic Name: CO2 Analyzer

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/382/

Generic Description:

Pump

Supplied Name: In situ pump profiler

Supplied Description:

Profiling was conducted with a pump profiler for using solid state gold-amalgam electrodes for voltammetry (Luther et al, 2008; Analytical Instrument Systems DLK-60). See Hudson et al (2019), doi: 10.1016/j.talanta.2019.02.076.

Instrument Type

Generic Name: Pump

Generic Description:

A pump is a device that moves fluids (liquids or gases), or sometimes slurries, by mechanical action. Pumps can be classified into three major groups according to the method they use to move the fluid: direct lift, displacement, and gravity pumps
