attribute	NC_GLOBAL	summary	String	This dataset provides geochemical data (major ions) for porewaters from sediment pushcores collected by DSV Alvin from the R/V Atlantis in June 2024 (AT50-24) at methane seeps in the Aleutian Trench, Alaska, USA. Also included is geochemical data (major ions) for water samples collected by Niskin bottle, both via DSV Alvin and via CTD cast from the ship. 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. We report 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 AS19-4 micrometer (um) 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).
