Caption

Interbedded basalt originating from 3 different volcanoes makes a complex, heterogenous aquifer influencing groundwater levels and groundwater discharge rates. Precipitation infiltrates into the young, porous basalt and flows in the subsurface before discharging to the coastal ocean as SGD. At the same time tides and waves push seawater into the coastal aquifer creating a complex subterranean estuary indicated by pink and blue colors.
