Description

Porewater sulfate concentrations from sediment cores P3, P6, P10, P11, P12 and P13, collected on the Guaymas Basin Ridge flanks and the Sonora Margin. Sediment cores were collected from R/V El Puma, the Pacific Coast research vessel of the Autonomous University of Mexico, leaving Guaymas on October 14, 2014, and heading to Mazatlan on October 27, 2014.

Methods & Sampling

Dataset acquisition description

Porewater sulfate concentrations were determined by ion chromatography in the Geochemistry lab of GEOMAR, Germany.

Data Processing Description

Dataset Processing Description

BCO-DMO Processing:
- created a column for core number;
- added lat, lon, and depth for each core from the metadata form;
- modified parameter names to conform with BCO-DMO naming conventions.

Instruments

Ion Chromatograph

Supplied Name: ion chromatography

Supplied Description:

Porewater sulfate concentrations were determined by ion chromatography in the Geochemistry lab of GEOMAR, Germany.

Instrument Type

Generic Name: Ion Chromatograph

Generic Description:

Ion chromatography is a form of liquid chromatography that measures concentrations of ionic species by separating them based on their interaction with a resin. Ionic species separate differently depending on species type and size. Ion chromatographs are able to measure concentrations of major anions, such as fluoride, chloride, nitrate, nitrite, and sulfate, as well as major cations such as lithium, sodium, ammonium, potassium, calcium, and magnesium in the parts-per-billion (ppb) range.
