From net sink to episodic source: Seasonal dissolved inorganic carbon budget in an intertidal basin

Limnology and Oceanography, Volume 71, Issue 10, October 2026.
Abstract The back‐barrier basin of Spiekeroog in the East Frisian Wadden Sea is a biogeochemically dynamic intertidal system that plays a key role in regulating coastal carbon fluxes and regional dissolved inorganic carbon (DIC) budgets. Compared to total alkalinity, DIC fluxes in this region remain poorly quantified, limiting a comprehensive ...

Submarine groundwater discharge from tropical islands: a review

, 2015
Submarine groundwater discharge (SGD) is a rarely recognized pathway for nutrients and other solutes from land to sea. The sensitive coastal ecosystems around tropical islands could be particularly affected by nutrient discharge associated with SGD in ...

Submarine groundwater discharge revealed by radium isotopes (Ra-223 and Ra-224) near a paleochannel on the Southern Brazilian continental shelf

Brazilian Journal of Oceanography, 2013
Submarine Groundwater Discharge (SGD) has been recognized as an important component of the ocean-continent interface. The few previous studies in Brazil have focused on nearshore areas.

Seasonal and Spatial Variability of Silicon Cycle in Godavari Tidal River Zone

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 10, October 2026.
Abstract Dam regulation of tropical monsoonal rivers enhances seasonal contrasts in the tidal river zone (TRZ) hydrology, altering the delivery of dissolved silicon (DSi) to the coastal ocean. Here, we identify the drivers of Si cycling in the Godavari TRZ and quantify their implications for Si delivery to the Bay of Bengal (BoB). We analyzed elemental

Estimating submarine groundwater discharge and associated nutrient inputs into Daya Bay during spring using radium isotopes

Water Science and Engineering, 2018
Daya Bay, a semi-enclosed bay in the South China Sea, is well known for its aquaculture, agriculture, and tourism. In recent years, many environmental problems have emerged, such as the frequent (almost yearly) occurrence of harmful algal blooms and red ...

Offshore Groundwater Salinization and Flushing in the Canterbury Bight During Glacial‐Interglacial Cycles

Water Resources Research, Volume 62, Issue 10, October 2026.
Abstract Offshore freshened groundwater (OFG) is a significant yet underexplored component of global water resources, occurring widely along many continental margins. However, its dynamics remain poorly constrained due to limited offshore observations and the absence of robust evaluation models for unambiguous emplacement interpretation.

Radium isotope tracing reveals that submarine groundwater discharge is a key influencing factor for blue carbon balance and mangrove carbon storage in the southern waters of Jinhai Bay

Journal of Hydrology: Regional Studies
Study region: Jinhai Bay, situated in the coastal zone of Guangxi, southern China (21°23′N–21°39′N, 109°17′E–109°29′E). Study focus: The objective of this study is to evaluate how submarine groundwater discharge (SGD) impacts the blue carbon balance in ...

Groundwater springs in the German Wadden Sea tidal flat: A fast-track terrestrial transfer route for nutrients and dissolved organic matter

Frontiers in Marine Science, 2023
Submarine groundwater discharge (SGD) connects fresh groundwater and marine ecosystems and conveys terrestrially derived dissolved organic matter (DOM) and nutrients from land to sea.

Dynamic Responses of Groundwater Flow and Salt Transport to Storm Surge Inundation in Unconfined Coastal Aquifers

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract Storm surges severely salinize coastal aquifers, yet post‐storm subsurface hydrodynamics remain poorly understood. We investigated surge inundation in unconfined tidal aquifers, revealing that subsurface flow recovers much faster than salinity distributions.

Widespread spring discharge drives major water–salt–heat fluxes in salt marshes

Limnology and Oceanography Letters, Volume 11, Issue 5, September 2026.
Abstract The occurrence, spatial distribution, and flux significance of submarine groundwater discharge (SGD) through preferential pathways in low‐permeability salt marshes remain poorly understood. Using thermal infrared imaging and in situ measurements, we mapped 983 saline springs in winter and 413 in summer across six tidal creeks on the muddy ...
