If
fresh submarine groundwater discharge approaches just 7 % of the total SGD, it would not only balance current groundwater recharge, but would steadily raise sea level by an additional 2 mm / year, even if there was no ocean warming and no melting glaciers.
Moosdorf (2017) has reviewed the locations and many human uses of
fresh submarine groundwater discharge around the world.

Groundwater that seeps into the coastal zone beneath the ocean's surface — termed
submarine groundwater discharge (SGD)-- is an important source of
fresh water and nutrients to nearshore coral reefs throughout the globe.
However, with improving techniques, researchers recently estimated total
submarine groundwater (saline and
fresh water combined) discharges suggesting a rate 3 to 4 times greater than the observed global river runoff, or a volume equivalent to 331 mm / year (13 inches) of sea level rise.
