New analysis highlights importance of groundwater discharge into oceans（图）
importance groundwater discharge into oceans
2021/1/28
An invisible flow of groundwater seeps into the ocean along coastlines all over the world. Scientists have tended to disregard its contributions to ocean chemistry, focusing on the far greater volumes...
Nutrient inputs to the coastal ocean from submarine groundwater discharge in a groundwater-dominated system: Relation to land use (Kona coast, Hawaii, U.S.A.)
Nutrient inputs the coastal ocean submarine groundwater discharge in a groundwater-dominated system Relation to land use
2014/4/17
We evaluated the magnitude and composition (in terms of salinity,223Ra and224 Ra activity, and nutrient concentrations) of submarine groundwater discharge (SGD) fluxes at 11 sites on the Kona coast of...
The importance of submarine groundwater discharge to the near shore nutrient supply in the Gulf of Aqaba (Israel)

We used two short-lived radium isotopes (223Ra, 224Ra) and a mass balance approach applied to the radium activities to determine the nutrient contribution of saline submarine groundwater discharge to ...
Large submarine groundwater discharge and benthic eutrophication in Bangdu Bay on volcanic Jeju Island, Korea
Large submarine groundwater discharge benthic eutrophication Bangdu Bay volcanic Jeju Island Korea
2014/5/13
We estimated the submarine discharge of groundwater (SGD) and associated nutrients into the semienclosed Bangdu Bay on a volcanic island, Jeju, Korea, by analyzing 222Rn, Ra isotopes (224Ra and 226Ra)...
Submarine groundwater discharge of nutrients and copper to an urban subestuary of Chesapeake Bay (Elizabeth River)
Submarine groundwater discharge nutrients and copper urban sub estuary Chesapeake Bay
2014/5/14
We investigated the role submarine groundwater discharge (SGD) plays in the delivery of nutrients and copper to the Elizabeth River (Virginia) estuary, a major subestuary of lower Chesapeake Bay. Usin...
Spatial distribution and budget for submarine groundwater discharge in Eckernfo¨rde Bay (Western Baltic Sea)
Spatial distribution budget groundwater discharge
2014/5/14
Submarine groundwater discharge (SGD) from subseafloor aquifers, through muddy sediments, was studied in
Eckernfo¨rde Bay (western Baltic Sea). The fluid discharge was clearly traced by
...
A carbon isotope method to quantify groundwater discharge at the land-sea interface
carbon isotope quantify groundwater discharge land-sea interface
2014/5/20
We present a new method to characterize and quantify groundwater discharge to estuaries and the coastal ocean. Using data from the Pages Creek estuary in the Cape Fear region of southeastern North Car...
Using natural distributions of short-lived radium isotopes to quantify groundwater discharge and recharge
short-lived radium isotopes recharge
2014/5/20
Radium activity in pore water of wetland sediments often differs from the amount expected from local production,
decay, and exchange with solid phases. This disequilibrium results from vertical trans...
Quantifying groundwater discharge through fringing wetlands to estuaries: Seasonal variability, methods comparison, and implications for wetland-estuary exchange
Quantifying groundwater discharge fringing wetlands to estuaries Seasonal variability, methods comparison implications for wetland-estuary exchange
2014/6/9
Because groundwater discharge along coastal shorelines is often concentrated in zones inhabited by fringing wetlands, accurately estimating discharge is essential for understanding its effect on the f...
