Imaging Point Source Groundwater Discharges in a Confined Coastal Aquifer Using Electrical Resistivity. [PDF]

Ground Water
Marine electrical resistivity tomography (ERT) is applied to characterize point‐source submarine groundwater discharge (PSGD) along NW Yucatán. ERT observations and forward modeling constrain conduit detectability under varying hydrogeological conditions.

Spatial Partitioning of Microbial Functional Potential Suggests Complex Nitrogen Cycling in a Subterranean Estuary. [PDF]

Environ Microbiol
Microbial communities in a Mediterranean subterranean estuary show spatially structured nitrogen‐cycling potential across hydrochemical zones. Microbial properties, more than environmental variables, predict NO2− and NH4+ concentrations, highlighting their key role in controlling nitrogen transformations prior to submarine groundwater discharge ...

Traditional and novel time-series approaches reveal submarine groundwater discharge dynamics under baseline and extreme event conditions [PDF]

Scientific Reports, 2021
Groundwater is a vital resource for humans and groundwater dependent ecosystems. Coastal aquifers and submarine groundwater discharge (SGD), both influenced by terrestrial and marine forces, are increasingly affected by climate variations and sea-level ...

Time‐Varying Hydroclimatic and Oceanic Controls on Arctic Submarine Groundwater Discharge Inferred Using Explainable AI

Geophysical Research Letters
Submarine groundwater discharge (SGD), an important component of coastal water and nutrient budgets, is challenging to monitor and predict in the Arctic given the remoteness and harsh conditions.

Large scale submarine groundwater discharge dominates nutrient inputs to China’s coast [PDF]

Nature Communications
Submarine groundwater discharge (SGD) is a nutrient source to coastal waters. However, most SGD estimates are restricted to a local scale and hardly distinguish contributions from fresh (FSGD) and recirculated (RSGD) SGD. Here, we compiled data on radium/

Submarine groundwater discharge and associated fluxes along the Kanyakumari coast of India using radon and nutrient mass balance approach [PDF]

Scientific Reports
Submarine groundwater discharge (SGD) acts as a carrier for elements, nutrients and pollutants into the ocean. This study estimated SGD along the Kanyakumari coast of India, using the Radon and nutrient mass balance approach.

Distribution of 222Rn in Seawater Intrusion Area and Its Implications on Tracing Submarine Groundwater Discharge on the Upper Gulf of Thailand

Lithosphere, 2022
Radon (222Rn) has been widely employed as a tracer for estimating submarine groundwater discharge (SGD). However, the uncertainty of the SGD estimation remains significant, due to the spatial variability of radon in groundwater.

Enhanced Productivity and Fish Abundance at a Submarine Spring in a Coastal Lagoon on Tahiti, French Polynesia

Frontiers in Marine Science, 2020
Submarine groundwater discharge (SGD), the direct discharge of groundwater into the sea, is abundant around the globe. Fresh SGD can occur as focused flow in submarine springs.
