Dissolved CO2 in natural waters: development of an automated monitoring system and first application to Stromboli volcano (Italy)
Gas–water interaction Dissolved CO2 Fluid geochemistry Geochemical monitoring
2015/8/27
The study of geochemical parameters applied to natural systems has provided improved knowledge of geochemical mechanisms of gas/rock dissolution in natural waters that are linked to gas–water and/or w...
Atmospheric dissolved iron deposition to the global oceans: effects of oxalate-promoted Fe dissolution, photochemical redox cycling, and dust mineralogy
global oceans oxalate-promoted Fe dissolution
2014/12/12
Mineral dust deposition is suggested to be a significant atmospheric supply pathway of bioavailable iron
(Fe) to Fe-depleted surface oceans.
Photochemical, microbial and metal complexation behavior of fluorescent dissolved organic matter in the aquatic environments
photodegradation microbial degradation metal complexation
2017/4/12
Chemical properties and reactivity of fluorescent dissolved organic matter (FDOM) are examined in this paper. They
are key issues to understand the biogeochemical processes in the aquatic environment...
Groundwaters of Mt. Vulture volcano, southern Italy: Chemistry and sulfur isotope composition of dissolved sulfate
Mt. Vulture volcano water-rock interaction silicate weathering hydrogeochemistry sulfur isotope composition
2017/8/9
We report the chemical composition of groundwaters—including the first data on the sulfur isotopic composition of dissolved sulfate—from the volcanic aquifers of Mt. Vulture, one of the most important...
Linking allochthonous dissolved organic matter and boreal lake sediment carbon sequestration: The role of light-mediated flocculation
Linking allochthonous dissolved organic matter boreal lake sediment carbon sequestration The role of light-mediated flocculation
2014/4/21
We measured flocculation of dissolved organic carbon (DOC) in the water from a humic lake (DOC = 14.9 mg C L-1) and from an adjacent mire (DOC = 25.7 mg C L-1), in in situ enclosure experiments with d...
Dissolved organic matter in abyssal sediments: Core recovery artifacts
Dissolved organic matter abyssal sediments Core recovery artifacts
2014/4/22
We report measurements of pore-water dissolved organic carbon (DOC), dissolved organic nitrogen, total dissolved carbohydrates, dissolved free monosaccharides, and ammonium in recovered deep-sea sedim...
Universal scaling of dissolved oxygen distribution at the sediment-water interface: A power law
Universal scaling dissolved oxygen distribution the sediment-water interface A power law
2014/5/13
Dissolved oxygen (DO) distribution at the sediment-water interface of a flow over a smooth bed is investigated for Reynolds numbers >360 and <4,090. These conditions are commonly encountered in stream...
Determination of the influence of pressure and dissolved water on the viscosity of highly viscous melts: Application of a new parallel-plate viscometer
Determination pressure dissolved water viscosity highly viscous melts:Application new parallel-plate viscometer
2012/4/1
A parallel-plate viscometer has been designed for use in an internally heated pressure vesse
(IHPV) at pressures up to 350 MPa and at temperatures up to 900 ?C. The viscosity of a melt is
determined...

Laboratory growth experiments were conducted to investigate the oxygen isotope effects associated with bacterial metabolism of phosphatic compounds commonly available in nature. The observed oxygen is...
The Effect of Dissolved Ligands on the Sorption of Cu(II) by Ca-Montmorillonite
Adsorption β-alanine Copper Ethylenediamine Malonic acid Modeling Montmorillonite
2011/12/28
The effects of three organic ligands on the adsorption of copper on Ca-montmorillonite were studied. The results indicate that these effects include three different processes: Enhanced uptake of posit...
