TLDR
The approach of this book to geochemistry can be summarized in the question: What happens, and how fast does it happen, when waters, solids, and gases interact in the earth's surface environment? The environment of the earths surface is made of solids and fluids, and the interactions among them are responsible for much of what is taking place in the physical world around us as mentioned in this paper.
Abstract
The approach of this book to geochemistry can be summarized in the question: What happens, and how fast does it happen, when waters, solids, and gases interact in the earths surface environment? The environment of the earths surface is made of solids and fluids, and theinteractions among them are responsible for much of what is taking place in the physical world around us. The dissolved load of natural waters and the materials of which sediments are made are the products of reactions taking place practically everywhere on land, in the atmosphere, and in the hydrosphere. Thus the term water and sediment environments applies effectivelly to much of the surface environment of the earth, including the zone of up to a few kilometers above and below the land and ocean surface. Evolution present itself to us as a more or less complex variety of processes-geological, physical, chemical, and biological. To this end, the inclusive title Geochemical Processes was chosen for the book, to introduce a text that emphasizes processes and time-dependent phenomena.

Processes in submerged soils – linking redox potential, soil organic matter turnover and plants to nutrient cycling

TL;DR: A review of the role of redox potential in nutrient cycling, soil organic matter turnover and the effect of plants on nutrient cycling processes in submerged soil is presented in this paper, where the active terminal electron acceptor for reduction processes follows the sequence O2, NO3−, MnO2, Fe3+, SO42− and CO2 where, in most cases organic matter is the electron donor.

Biogeochemistry of the sediment–water interface in the littoral of an acidic mining lake studied with microsensors and gel-probes

TL;DR: A protocol for the application of gel probes for the analysis of iron and sulfate in acidic mining lakes was developed and the combination of microsensor and DET data allowed the characterisation and localisation of iron turnover on a millimetre scale.

Non-residual Sr of the sediments in Daihai Lake as a good indicator of chemical weathering

TL;DR: In this paper, the variation patterns of Rb and Sr of different forms in sediments of Daihai Lake were investigated, and the results showed that the Rb of various forms display noticeably different variation patterns due to their different sources and associated environmental processes.

A routine device for high resolution bottom water sampling

TL;DR: The multi-horizon bottom water sampler (BoWaSnapper) presented here was developed for instantaneous sampling of the transition zone above the seafloor and can be deployed in all types of water bodies from coastal seas to full ocean depth.

Nutrient release rates from the sediments of Saginaw Bay, Lake Huron

TL;DR: In this article, the authors measured the production rates and pore water profiles of solutes in the fine-grained sediments of Saginaw Bay, imply corresponding steady-state fluxes to the overlying water of 1.1-1.3 mM at 23.5°C.
