Coastal Groundwater Management with Nearshore Resource Interactions [PDF]

This paper develops a regional hydrologic-ecologic-economic model of groundwater use and a nearshore ecosystem. Particularly, we model coastal groundwater management and its effects on discharge, nearshore water quality, and marine biota (e.g ...

Recirculated submarine groundwater discharge dominates nutrient inputs and enhances eutrophication risk in a coastal lagoon

Limnology and Oceanography, Volume 71, Issue 4, April 2026.
Abstract Submarine groundwater discharge (SGD) is a widely recognized pathway for nutrient transport to coastal systems. Prior studies overlook the unique biogeochemical signatures of different SGD pathways, neglecting their differences in biogeochemical transformations and spatiotemporal factors.

The Seasonal Impact of the Island Mass Effect on Coastal Biogeochemistry and Phytoplankton Assemblage: The Case of the Tropical and Volcanic Island of Guadeloupe (French West Indies)

Journal of Geophysical Research: Oceans, Volume 131, Issue 4, April 2026.
Abstract The Island Mass Effect (IME) in tropical regions remains understudied, despite its potential to fertilize oligotrophic oceanic gyres and impact on higher trophic levels. Guadeloupe provides an ideal case study of IME due to its diverse nutrient sources, dual exposure to the Caribbean Sea on the western coast and Atlantic Ocean on the eastern ...

Assessing land–ocean connectivity via submarine groundwater discharge (SGD) in the Ria Formosa Lagoon (Portugal): combining radon measurements and stable isotope hydrology [PDF]

, 2015
Natural radioactive tracer-based assessments of basin-scale submarine groundwater discharge (SGD) are well developed. However, SGD takes place in different modes and the flow and discharge mechanisms involved occur over a wide range of spatial and ...

SUBMARINE GROUNDWATER DISCHARGE MEASUREMENT ON THE SANDY UNCONFINED AQUIFER AT THE CARNAVAL BEACH, ANCOL (JAKARTA BAY) [PDF]

Submarine groundwater discharge (SGD) is defined as all direct discharge of subsurface fluids into coastal zone. Components of SGD consist of fresh submarine groundwater discharge and the recirculated saline seawater discharge. SGD could act as a pathway

Submarine Groundwater Discharge and Stream Baseflow Sustain Pesticide and Nutrient Fluxes in Faga'alu Bay, American Samoa

Frontiers in Environmental Science, 2019
It is increasingly recognized that groundwater discharge in the form of stream baseflow and submarine groundwater discharge (SGD) plays an important role in contaminant transport. This study seeks to demonstrate the importance of groundwater flow for the

Evaluations of spatial distribution of submarine groundwater discharge [PDF]

, 2006
The paired catchments with the same basin size and meteorological condition but different geology were selected to compare the fresh submarine groundwater discharge (SGD) rate observed by seepage meters with value calculated from water balance method in ...

Global land–ocean linkage: direct inputs of nitrogen to coastal waters via submarine groundwater discharge

Environmental Research Letters, 2013
The role of submarine groundwater discharge (SGD), the leakage of groundwater from aquifers into coastal waters, in coastal eutrophication has been demonstrated mostly for the North American and European coastlines, but poorly quantified in other regions.
