attribute	NC_GLOBAL	summary	String	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 concentrations of fluoride, acetate, formate, chloride, bromide, nitrate, sulfate, thiosulfate, and phosphate anions and lithium, sodium, potassium, magnesium, and calcium cations. Measurements were made using the Thermo Dual Dionex Integrion HPIC ion chromatography system with either a 250-millimeter (mm) Dionex IonPac AS19-4um column (anions) or a 250 mm Dionex IonPac CS16-4um column (cations), in the Resnick Water and Environment Laboratory at the California Institute of Technology (Caltech).
