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...
Researchers Develop Novel Approach for Quantifying Nitrate Discharge from Groundwater to Streams
Researchers Quantifying Nitrate Discharge Groundwater Streams
2016/11/29
Novel groundwater sampling (age, flux, and nitrate) carried out beneath a streambed and in wells was used to estimate (1) the current rate of change of nitrate storage, dSNO3/dt, in a contaminated unc...
Monitoring of fumarole discharge and CO2 soil degassing in the Azores: contribution to volcanic surveillance and public health risk assessment
volcanology geochemistry soil degassing monitoring risk
2015/9/10
Fluid geochemistry monitoring in the Azores involves the regular sampling and analysis of gas discharges from
fumaroles and measurements of CO2 diffuse soil gas emissions. Main degassing areas under ...
DISCHARGE ESTIMATION FOR THE INVISIBLE AMAZON RIVER BRANCHES IN SAR IMAGES
Forestry Geomorphology Monitoring Visualization SAR
2015/7/30
Recently, desertification and degradation of water cycle by deforestation in the Amazon, South America, have become a serious
problem. In this study, it was attempted to estimate the discharge of th...

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...

The direct influence of freshwater discharge along the coastal regions is observed in several processes following a wide spectrum on spatial and temporal variability. The knowledge of relative importa...
Ethanol reforming in non-equilibrium plasma of glow discharge
Ethanol reforming non-equilibrium plasma of glow discharge Plasma Physics
2012/5/29
The results of a detailed kinetic study of the main plasma chemical processes in non-equilibrium ethanol/argon plasma are presented. It is shown that at the beginning of the discharge the molecular hy...
Simultaneous and sensitive analysis of inorganic and organic gaseous compounds by pulsed discharge helium ionization detector (PDHID)
micropacked column simultaneous and sensitive analysis organic gases inorganic gases
2017/4/11
A simple gas chromatographic method has been developed for the simultaneous and sensitive analysis of inorganic
(H2, CO, and CO2) and organic gaseous compounds (CH4, C2H4, C2H6, C3H6, C3H8, iso-C4H10...
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...
Uniqueness theorem for the non-local ionization source in glow discharge and hollow cathode

2012/4/19
The paper is devoted to the proof of the uniqueness theorem for solution of the equation for the non-local ionization source in a glow discharge and a hollow cathode in general 3D geometry. The theore...
Mechanism of Stepped Leaders in a Simple Discharge Model
Mechanism Stepped Leaders Discharge Model Plasma Physics
2011/8/5
Abstract: We construct a one-dimensional model for the stepped leader in the filamental discharge by simplifying an electric-circuit model of discharge. We find that the leader of the discharge moves ...
