©2020 Biological and Chemical Oceanography Data Management Office.This dataset provides geochemical data (major ions) for porewaters from sediment pushcores collected by a remotely-operated vehicle (ROV) deployed from the R/V Western Flyer in May 2021 (WF05-21) at the Del Mar and Santa Monica Seeps and in Newport Canyon, California, USA. Cores were sectioned into 1-3 centimeter (cm) horizons, and porewater was extracted shipboard using an argon-pressurized squeezer. Porewater samples were frozen at sea and thawed just before analysis. This dataset reports conc...

Sediment pushcores were collected by a remotely-operated vehicle (ROV Doc Ricketts) from the R/V Western Flyer in May 2021 (cruise ID WF05-21) at the Del Mar Seep (32.9043, -117.7824), Santa Monica Seep Mound 800 (33.7993, -118.6465), Santa Monica Seep Mound 863 (33.7891, -118.6683), and Newport Canyon (33.5450, -117.9251). Pushcores were manually sectioned into 1- or 3-centimeter (cm) horizons using plastic rings, and porewaters were extracted using a KC Denmark squeezer. Samples for ion chromatography were frozen shipboard and thawed immediately prior to analysis. Measurements were made using a Thermo Dual Dionex Integrion HPIC ion chromatography system with either a 250-millimeter (mm) Dionex IonPac AS19-4um column (anions) with 50 mm guard column or a 250 mm Dionex IonPac CS16-4um column (cations) with a 50 mm guard column, in the Resnick Water and Environment Laboratory at the California Institute of Technology (Caltech).
