Ba/Ca in foraminifera shells as a proxy of submarine groundwater discharge

Limnology and Oceanography Letters, 2023
Submarine groundwater discharge (SGD) can have a profound influence on marine environments and elemental biogeochemical cycles in coastal waters. We have explored the feasibility of using Ba/Ca ratios of benthic foraminiferal shells as a proxy of SGD ...

Mechanisms of Seawater Intrusion Under Temporal Evolution of Geomorphology in Coastal Aquifers

Water Resources Research, Volume 62, Issue 7, July 2026.
Abstract Intertidal geomorphological evolution plays a vital role in coastal aquifer ecosystems. However, current studies on groundwater dynamics and water‐salt transport mainly focus on idealized linear or simplified irregular profiles. The poorly characterized mixing of saltwater and freshwater under evolving conditions has seriously constrained the ...

Radium isotopes distribution and submarine groundwater discharge in the Bohai Sea

, 2019
In order to characterize the radium distribution and submarine groundwater discharge (SGD) in the Bohai Sea area, the three isotopes 223Ra, 224Ra and 228Ra in different water bodies were measured in a 4-year period with the radium-delayed coincidence ...

Numerical Investigation of Storm Surge Effects on Denitrification in Nearshore Aquifers

Water Resources Research, Volume 62, Issue 7, July 2026.
Abstract Coastal aquifers are highly dynamic environments, sensitive to both regular hydrodynamic forcing and extreme events. Among these, storm surges can significantly alter subsurface flow by expanding the upper saline plume (USP), modifying residence times, and intensifying mixing between fresh groundwater and seawater.

Combining seepage meters and amphibious electric resistivity tomography to investigate pathways of submarine groundwater discharge

Submarine groundwater discharge (SGD) plays a pivotal role in coastal biogeochemistry, yet it is still challenging to accurately quantify water and solute fluxes driven by this process due to its complex hydrogeological dynamic. This work aims to improve

The Global Contribution of Individual Submarine Groundwater Discharge Components to the Ocean

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Saline submarine groundwater discharge (SSGD) contributes to ocean chemistry through water‐rock interactions as seawater circulates in coastal aquifers. Its components, driven by different mechanisms, exhibit varying residence times and degrees of chemical alteration, so constraining solute fluxes requires quantifying each component.

Renewable Resource Management with Stock Externalities: Coastal Aquifers and Submarine Groundwater Discharge [PDF]

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

Global subterranean estuaries modify groundwater nutrient loading to the ocean

Limnology and Oceanography Letters
Terrestrial groundwater travels through subterranean estuaries before reaching the sea. Groundwater‐derived nutrients drive coastal water quality, primary production, and eutrophication.

Hydrological and Thermal Dynamics of a Supra‐Permafrost Subterranean Estuary

Water Resources Research, Volume 62, Issue 5, May 2026.
Abstract Subterranean estuaries (STEs), where groundwater interacts with seawater, influence surface and subsurface coastal ecology and biogeochemistry. In Arctic‐STEs overlying permafrost, groundwater flow and heat transport determine the fate of organic matter.
