Submarine groundwater is richer in nutrients compared to surface (river) water and therefore has been considered to be an essential component of biological production in marine coastal ecosystems.

Nitrogen biogeochemistry of submarine groundwater discharge [PDF]
To investigate the role of the seepage zone in transport, chemical speciation, and attenuation of nitrogen loads carried by submarine groundwater discharge, we collected nearshore groundwater samples (n = 328) and examined the distribution and isotopic signature (δ15N) of nitrate and ammonium.

Groundwater Discharge in the Arctic: A Review of Studies and Implications for Biogeochemistry
Groundwater discharge, including submarine groundwater discharge, discharge to lakes and rivers, and subglacial discharge, affects freshwater and marine ecosystems across the globe. The implications for biogeochemistry include the transport of nutrients,

Unheralded Submarine Groundwater Discharge [PDF]
Land meets the ocean in the coast zone, which is of great importance for aquaculture, fisheries, tourism and transportation, among other things. As fifty percent of the world population lives within 100 km of the coast, human activities have put tremendous pressure on the coastal environment.

Submarine groundwater discharge
Measurement of groundwater discharge to rivers, lakes, estuaries, and oceans was the subject of a special session at the meeting of the North American Benthological Society, held at Virginia Polytechnic Institute and State University, Blacksburg, Va., May 22–25, 1990. The meeting was attended by more than 40 marine and aquatic ecologists, hydrologists,

Submarine groundwater discharge in Ría de Vigo
Submarine Groundwater Discharge (SGD), i.e. any flow across the sediment-water interface (Burnett et al. 2003), is now recognized as the major source of continental water to the global ocean, thus exerting a major control over coastal water composition (Kwon et al. 2014).

The authors here present the global entry of nutrients into marine systems through fresh submarine groundwater discharge to be below 1%. However, they also identify hotspots and argue that about 25% of world’s estuaries are at danger of eutrophication.

Assessment of groundwater discharge pathways in a till-dominated coastal aquifer
Study region: Mabou Harbour located in Cape Breton Island, Nova Scotia, Canada, is representative of the many natural harbours throughout the Maritime region of Canada as the surrounding landscape is overlain by glacial deposits, predominantly composed ...
