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...
An investigation of submarine groundwater–borne nutrient fluxes to the west Florida shelf and recurrent harmful algal blooms
An investigation submarine groundwater–borne nutrient fluxes the west Florida shelf recurrent harmful algal blooms
2014/4/4
A cross-shelf, water-column mass balance of radon-222 (222Rn) provided estimates of submarine groundwater discharge (SGD), which were then used to quantify benthic nutrient fluxes. Surface water and g...

2014/4/2
A cross-shelf, water-column mass balance of radon-222 (222Rn) provided estimates of submarine groundwater discharge (SGD), which were then used to quantify benthic nutrient fluxes. Surface water and g...
The effect of groundwater advection on salinity in pore waters of permeable sediments
groundwater advection salinity in pore waters permeable sediments
2014/4/18
Measurements of the upward advection and pore-water profiles of salinitywere made at three coastal settings(the Venice Lagoon, Italy; Jamaica Bay, New York; and Mattituck, New York). Coincident measur...
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...
Quantification of point-source groundwater discharges to the ocean from the shoreline of the Big Island, Hawaii
Quantification of point-source groundwater discharges the ocean shoreline of the Big Island Hawaii
2014/4/18
Aerial thermal infrared imaging has revealed that submarine groundwater discharge (SGD) along the western coast of the Big Island of Hawaii is often focused as point-source discharges that create buoy...

Quantifying saline groundwater flow into a freshwater lake using the Ra isotope quartet: A case study from the Sea of Galilee (Lake Kinneret), Israel
Quantifying saline groundwater flow freshwater lake
2014/4/17
We investigated the Ra isotope quartet in order to quantify the discharge of saline groundwater into a
freshwater lake. The activities of 226Ra, 228Ra, 223Ra, and 224Ra were measured in the Sea of Ga...
Groundwater recharge and discharge dynamics in an arid-zone ephemeral lake system, Australia
Groundwater recharge discharge dynamics
2014/4/17
The Coongie Lakes are a series of ephemeral freshwater lakes on the lower reaches of Cooper Creek, a large
intermittent river of the arid Lake Eyre Basin, Australia. Hydrogeological, chemical, and is...
Submarine discharge of nutrient-enriched fresh groundwater at Stinson Beach, California is enhanced during neap tides
Submarine discharge nutrient-enriched fresh groundwater Stinson Beach California enhanced during neap tides
2014/4/18
The influence of fortnightly spring–neap tidal variability on submarinedischarge of fresh and saline groundwater was examined at Stinson Beach, California. Stinson Beach is aresidential community that...
Are groundwater inputs into river-dominated areas important? The Chao Phraya River Gulf of Thailand
groundwater inputs into river-dominated Chao Phraya River Gulf of Thailand
2014/5/5
We used the natural geochemical tracers radon-222 and radium isotopes (223Ra, 224Ra, 226Ra, 228Ra) to assess exchange rates between the Chao Phraya River and the Gulf of Thailand, and the magnitude of...
Groundwater-transported dissolved organic nitrogen exports from coastal watersheds
Groundwater-transported dissolved organic nitrogen exports coastal watersheds
2014/5/5
We analyzed groundwater-transported nitrogen (N) exports from 41 watershed segments that comprised 10 Cape Cod, Massachusetts watersheds to test the hypotheses that chemical form of N exports is relat...
The importance of submarine groundwater discharge to the near shore nutrient supply in the Gulf of Aqaba (Israel)
