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 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

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...
Using Thermal Infrared Imagery (TIR) for Illustrating the Submarine Groundwater Discharge into the Eastern Shoreline of the Dead Sea-Jordan
Jordan thermal infrared Dead Sea discharge
2009/2/5
Many of thermal anomalies that are indicator of discharge zones of warmer water were observed along the Dead Sea shoreline at the areas of Zarka Ma’in, Zara and Al-Mujeb. The groundwater discharge loc...
Direct determination of total and fresh groundwater discharge and nutrient loads from a sandy beachface at low tide (Cape Henlopen, Delaware)
Direct determination of total and fresh groundwater discharge nutrient loads from a sandy beachface low tide (Cape Henlopen, Delaware)
2014/4/22
Total groundwater discharge from a sandy seepage site to the Delaware Bay at Cape Henlopen, Delaware, was determined together with the associated nutrient loads by trapping the discharge from a length...
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...

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)...
