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 contribution of groundwater discharge to the overall water budget of two typical Boreal lakes in Alberta/Canada estimated from a radon mass balance
groundwater discharge overall water budget typical Boreal lakes radon mass balance
2010/2/1
Radon-222, a naturally-occurring radioisotope with a half-life of 3.8 days, was used to estimate groundwater discharge to small lakes in wetland-dominated basins in the vicinity of Fort McMurray, Cana...
Groundwater Discharge through Springs with Well-Defined Outlets A Case Study from Jeløya–Moss,S. Norway
Groundwater Discharge Well-Defined Outlets Jelø ya–Moss
2009/10/28
From the area of JeLya - Moss, southern Norway, five springs draining
fissured-rock aquifers, and one artesian well draining confined water from a
sand and gravel aquifer were studied during the yea...
Dynamic analysis of groundwater discharge and partial-area contribution to Pukemanga Stream, New Zealand
Dynamic analysis groundwater discharge
2009/5/4
The proportion and origin of groundwater contribution to streamflow from agricultural catchments is relevant to estimation of the effects of nitrate leached from the soil on the quality of surface wat...
Influence of aquifer and streambed heterogeneity on the distribution of groundwater discharge
aquifer streambed heterogeneity groundwater discharge
2009/4/27
The spatial distribution of groundwater fluxes through a streambed can be highly variable, most often resulting from a heterogeneous distribution of aquifer and streambed permeabilities along the flow...
Characterising and modelling groundwater discharge in anagricultural wetland on the French Atlantic coast
wetland, hydrology groundwater modelling marsh
2009/3/11
Interaction between a wetland and its surrounding aquifer was studied in the Rochefort agricultural marsh (150 km2). Groundwater discharge in the marsh was measured with a network of nested piezometer...
Hydrologic forcing of submarine groundwater discharge: Insight from a seasonal study of radium isotopes in a groundwater-dominated salt marsh estuary
Hydrologic forcing of submarine groundwater discharge Insight from a seasonal study of radium isotopes a groundwater-dominated salt marsh estuary
2014/4/22
A seasonal study of radium-derived submarine groundwater discharge (SGD) and associated nitrogen fluxes was carried out in a salt marsh estuary between 2001 and 2003 (Pamet River Estuary, Massachusett...
The importance of submarine groundwater discharge to the near shore nutrient supply in the Gulf of Aqaba (Israel)
submarine groundwater discharge near shore nutrient supply the Gulf of Aqaba
2014/5/4
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)...

2010/1/12
Submarine groundwater discharge was quantified by a variety of methods for a 4-day period during the early summer of 2004, in Salt Pond, adjacent to Nauset Marsh, on Cape Cod, USA. Discharge estimates...
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...
