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...
Quantification of point-source groundwater discharges to the ocean from the shoreline of the Big Island, Hawaii
point-source groundwater discharges the shoreline of the Big Island
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 buo...
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)
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 ...
A modern isotope record of changes in water and carbon budgets in a groundwater-fed lake: Blue Lake, South Australia
modern isotope record changes in water carbon budgets groundwater-fed lake Blue Lake South Australia
2014/5/22
Groundwater is often a major component of lake water and chemical balances. Alteration in catchment subsurface water balances through land-use change and pumping can affect lake biogeochemical cycles ...
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...
Effects of groundwater flux on open-channel estimates of stream metabolism
groundwater flux open-channel estimates stream metabolism
2014/5/26
The open-channel oxygen method can produce precise estimates of photosynthesis (P) and respiration (R) over a wide range of stream conditions. It is widely recognized that flux of groundwater contribu...
