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...
Development and application of the WRFPLUS-Chem online chemistry adjoint and WRFDA-Chem assimilation system
Development and application chemistry adjoint
2015/8/6
Here we present the online meteorology and
chemistry adjoint and tangent linear model, WRFPLUSChem (Weather Research and Forecasting plus chemistry),
which incorporates modules to treat boundary lay...
Modelling methane emissions from natural wetlands by development and application of the TRIPLEX-GHG model
development and application Modelling methane emissions
2014/12/18
A new process-based model TRIPLEX-GHG was
developed based on the Integrated Biosphere Simulator
(IBIS), coupled with a new methane (CH4) biogeochemistry
module (incorporating CH4 production, oxidat...
Application of PTR-MS to an incubation experiment of the marine diatom Thalassiosira pseudonana
dimethyl sulfide, isoprene, methanethiol
2017/4/12
Emission of trace gases from the marine diatom Thalassiosira pseudonana (CCMP1335) was continuously monitored
with a proton transfer reaction-mass spectrometry (PTR-MS) in an axenic batch culture sys...
Testing seawater Sr isotopic variability on a glacial-interglacial timescale: An application of latest high-precision thermal ionization mass spectrometry
TIMS Sr isotopes seawater glacial-interglacial cycle
2017/8/9
Stability in seawater 87Sr/86Sr ratios over a glacial-interglacial timescale has gained the consensus, yet inter-site inconsistency exists in the previous data employed for validation of this issue. T...
Application of the Correspondence-Type Geostatistical Analysis on the Co, Ni, As, Ag and Au Concentrations of the Listwaenites from Serpentinites in the Divrigi and Kuluncak Ophiolitic Mélanges
Serpentinites Kuluncak Ophiolitic Mélanges Ag Co Ni
2009/7/8
The main aim of this research was to find out correlation-if there is any-among Co, Ni, As, Ag and Au concentrations in three different listwaenite sampling sets in Divirigi and Hekimhan areas. The lo...
New preconcentration technique of Zr, Nb, Mo, Hf, Ta and W employing coprecipitation with Ti compounds: Its application to Lu-Hf system and sequential Pb-Sr-Nd-Sm separation
coprecipitation Ti compounds Lu-Hf Pb-Sr-Nd isotope analysis preconcentration
2017/8/10
A new preconcentration technique of Zr, Nb, Mo, Hf, Ta and W has been invented employing coprecipiation with Ti compounds. Silicate samples were digested by HF with addition of Ti. Subsequent drying w...
Relationship between geological structure and helium isotopes in deep groundwater from the Osaka Basin: Application to deep groundwater hydrology
helium isotopes noble gas groundwater hydrology Osaka basin
2017/8/10
The relationship between geological structure and helium isotopes is discussed for deep groundwaters from the Osaka sedimentary basin, southwest Japan, to understand dissolved He in groundwater for hy...
Isotopic fractionation of SO2 and H2S gases during the absorption by KOH solution, with the application to volcanic gas monitoring at Miyakejima Island, Japan
volcanic gas Miyakejima isotopic fractionation diffusion sulfur
2017/8/10
The chemical trap method has been used for monitoring of volcanic activity. In this method, a strong alkaline water solution was exposed in ambient air. Acidic gases, such as SO2, H2S, HCl and HF are ...
