Modelling of Geochemical Tracers in the Ocean

1990
The basic mechanisms of marine biology and chemistry which influence the atmospheric concentration of carbon dioxide are embedded in the three-dimensional current field of an OGCM. The modelled tracers are phosphate, alkalinity, oxygen, dissolved inorganic carbon, particulate organic carbon, and calcite, the latter three in three isotopes.

Geochemical Characterization of Deep Groundwater in KURT Using Geochemical Modeling

Journal of Environmental Engineering, 2012
A total of 11 boreholes were drilled at depths of 20–500 m to investigate the geochemical characteristics of groundwater at the KAERI Underground Research Tunnel (KURT) site. The groundwater chemistry up to a depth of 500 m at the KURT site was divided into Ca-HCO3 and Na-Ca-HCO3 types in the groundwater system. Ca-HCO3 and Na-Ca-HCO3 types showed that

Spectroscopy as a tool for geochemical modeling

SPIE Proceedings, 2011
This study focused on testing the feasibility of up-scaling ground-spectra-derived parameters to HyMap spectral and spatial resolution and whether they could be further used for a quantitative determination of the following geochemical parameters: As, pH and Clignite content.

Geochemical Models

1994
Abstract The usefulness of geochemical modeling in diagenesis lies in the ability to analyze processes that cannot be measured directly in the laboratory, either due to the time element (slow kinetics) or, more typically, metastable equilibria.

Geochemical Reaction Modeling

1996
Geochemical reaction modeling plays an increasingly vital role in several areas of geoscience, from environmental geochemistry and petroleum geology to the study of geothermal and hydrothermal fluids. This book provides an up-to-date overview of the use of numerical methods to model reaction processes in the Earth's crust and on its surface.
