This report includes geological and chemical data that were compiled sediment and pore water analyses of cores collected from the Nares Abyssal Plain, in the north western
Atlantic Ocean. Sediment samples were taken from 5 cores. Sediment analyses included colour, mean grain size, water content, organic carbon, total carbon, total metals (Ca, Mg, K, Si, Al, Fe, Mn, Zn, Cu, Ni), weak acid leachable metals (Fe, Mn, Zn,
Cu, Ni), and reducible metals (Fe, Mn, Zn, Cu,Ni). Pore water analyses included major cations (Na, Mg, Ca, K), nutrients (silicate, nitrate, phosphate), total alkalinity, total sulfate, trace metals (Mn, Fe, Zn, Cu, Ni, Cd), free hydrogen ion, free
electrons and sulfide ion.
