Description

Data from samples collected at the shallow-water hydrothermal vent sites at Paleochori Bay, Milos Island, Greece, and includes the chemical composition (anion, cation, trace elements/metals) of vent fluids sampled.

Methods & Sampling

Dataset acquisition description

Fluid samples were collected from the water column close to the shallow-water venting sites and from the interstitial waters of all cores at 2 cm intervals. Fluids and gases were also sampled from the subaerial sites. Samples returned to the Geophysical Lab were analyzed to determine dissolved concentrations of: organic acids and a range of major anions/cations species (e.g. SO42-, PO42-, SNH3, NO3-, Cl-, Na+, K+, Ca2+, and Mg2+) including trace elements and metals. We used ion chromatography (Metrohm "MIC-3 Advanced IC, Metrosep A supp 7-250/16-250; C4- 250 columns). Fluids were analyzed for metal and trace element concentrations at the MC-ICP-MS facility of Prof. Michael Bizimis at the University of South Carolina.
