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...
Coastal Sediment Dynamics and River Discharge as Key Factors Influencing Coastal Ecosystem Productivity in Southeastern Lake Michigan
Coastal Sediment Dynamics River Discharge Coastal Ecosystem Productivity Southeastern Lake Michigan
2015/7/22
A central question addressed by the Episodic Events in the Great Lakes Experiment (EEGLE) was the extent to which the spring phytoplankton bloom in southern Lake Michigan is influenced by a recurrent ...
Hydrothermal Discharge During Submarine Eruptions:The Importance of Detection,Response,and New Technology
Hydrothermal Discharge Submarine Eruptions Detection Response New Technology
2015/7/14
Submarine volcanic eruptions and intrusions construct new oceanic crust and build long chains of volcanic islands and vast submarine plateaus. Magmatic events are a primary agent for the transfer of h...
River Discharge to the Coastal Ocean:A Global Synthesis
River Discharge Coastal Ocean Global Synthesis
2015/7/13
There was a time when "blue water" oceanographers didn't think much about the coastal oceans, let alone the arterial strands of freshwater that supply them with sediment, solutes, organisms, and a var...
Discharge of dissolved black carbon from a fire-affected intertidal system
Discharge of dissolved black carbon from a fire-affected intertidal system
2014/4/4
We report substantial tidal fluxes of dissolved black carbon (DBC) in a fire-affected marsh in the northern Gulf of Mexico. DBC was molecularly determined as benzenepolycarboxylic acids in a tidal cre...
The Mekong River plume fuels nitrogen fixation and determines phytoplankton species distribution in the South China Sea during low and high discharge season
The Mekong River plume fuels nitrogen fixation determines phytoplankton species distribution the South China Sea low and high discharge season
2014/4/17
The influence of the Mekong River (South China Sea) on N2 fixation and phytoplankton distribution was investigated during the lowest- and highest-discharge seasons (April 2007 and September 2008, resp...
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 role of effective discharge in the ocean delivery of particulate organic carbon by small, mountainous river systems
The role of effective discharge in the ocean delivery particulate organic carbon by small mountainous river systems
2014/4/16
Recent research has shown that small, mountainous river systems (SMRS) account for a significant fraction of the global flux of sediment and particulate organic carbon (POC) to the ocean. The enormous...
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...
The Dynamics of Oceanic Fronts. Part II：Shelf Water Structure Due to Freshwater Discharge
Shelf Water Structure Freshwater Discharge Oceanic Fronts
2009/2/10
In Part I of this series, a framework was introduced for the study of oceanic frontal dynamics. The dynamics was studied by posing an initial value problem, starting with a near-surface discharge of b...
Why Does the Amazon Water Flow to the North after Its Discharge?
Amazon Water Flow Discharge northern coast
2009/1/4
Through a simple model, it is demonstrated that earth's sphericity (the beta effect) imposes a severe constraint on the discharge pattern near the equator. Using either bottom or lateral friction to c...
Evidence for the inherent unsteadiness of a river plume: Satellite observations of the Niagara River discharge
inherent unsteadiness of a river plume Satellite observations Niagara River discharge
2014/4/21
We present satellite data from the Niagara River plume showing that a large eddy, or bulge, forms and grows in the plume near the mouth of the river. The plume consists of a semicircular bulge region ...
Penetration of Buoyant Coastal Discharge onto the Continental Shelf: A Numerical Model Experiment
Buoyant Coastal Continental Shelf A Numerical Model
2008/7/21
Plumes of buoyant water produced by inflow from rivers and estuaries are common on the continental shelf. Typically they turn anticyclonically to flow alongshelf as buoyancy-driven coastal currents. D...

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...
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 ...
