This scientific coring project seeks to extend our understanding of the current and past states of fluid composition, pressure, and temperature in continental shelf environments. In many coastal settings worldwide, the distribution of freshwater within continental shelf sediments is far out of equilibrium with modern sea level. One of the most remarkable examples is found on the Atlantic continental shelf off New England where groundwater within shallow Pliocene-Pleistocene sand aquifers over 100 km offshore has low salinity (3000 mg/l or less). This project will test several hypotheses to help constrain rates, directions, and mechanisms of groundwater flow and chemical fluxes in continental shelf systems.
