Submarine groundwater discharge is a process by which water exits coastal aquifers and enters the ocean. This can be terrestrial freshwater or salty seawater that intruded into the porous aquifer at the ocean’s edge. A new study, published in Scientific Reports by University of Hawai’i at Mānoa researchers, showed that while precipitation and sea level drive coastal groundwater levels, it is sea level, especially tides, that play gatekeeper on the amount of groundwater discharging to Hawai’i’s coastal zone.
