Contribution of Submarine Groundwater Discharge to Select Biogeochemical Fluxes in St. Louis Bay, Mississippi
<p>This thesis assesses the role of submarine groundwater discharge (SGD) in St. Louis Bay, Mississippi. Located along the northern Gulf of Mexico, St. Louis Bay (SLB) is a semi-enclosed bay that is important to the local area for recreation and tourism. SGD is the movement of any water into the …

Distribution and behavior of trace metals in the subterranean estuary of an Arctic coastal lagoon
… alter concentrations of chemical constituents of groundwater. With warming in the Arctic and the subsequent permafrost thaw, the relative importance of submarine groundwater discharge (SGD) to ocean chemical budgets will grow. In this study, we examined the distribution of select trace metals (Fe, …

Seasonal dynamics in costal aquifers : investigation of submarine groundwater discharge through field measurements and numerical models
The fresh and saline groundwater flowing from coastal aquifers into the ocean comprise submarine groundwater discharge (SGD). This outflow is an important pathway for the transport of nutrients and contaminants, and has been shown to adversely affect coastal ecosystems in many areas of the world. …

Temporal variability in chemical cycling of the subterranean estuary and associated chemical loading to the coastal ocean
At the land-ocean interface, terrestrial groundwater interacts with seawater to form a subterranean estuary, which can play host to dynamic biogeochemical cycling of nutrients, trace metals and radionuclides. This chemically altered groundwater enters the ocean through submarine groundwater …

Submarine Groundwater Discharge in the Southern Chesapeake Bay: Constraints From Numerical Models
… fluid flow within the coastal zone to produce submarine groundwater discharge (SGD). Groundwater flowing from the seabed serves as a significant pathway for contaminants and nutrients, producing an active biogeochemical reaction zone. In order to quantify the importance of SGD in geochemical …

The design and testing of a procedure to locate fresh submarine groundwater discharge in Cyprus
… an experimental procedure for identifying fresh submarine groundwater discharge (SGD) in Cyprus. SGD is a flow of water from coastal aquifers into the ocean driven by a hydraulic gradient and other forces. Understanding SGD is crucial for informed groundwater management. In some cases, SGD …

Investigating groundwater derived nutrient fluxes within Tauranga harbour, New Zealand
Submarine groundwater discharge (SGD) is one of the key pathways that connects land and ocean, delivering freshwater, nutrients, carbon, metals, and other chemical constituents to coastal waters. In New Zealand, local Māori have had a strong cultural connection to this natural process for …
