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.

Summer and winter denitrification rates in western Arctic shelf sediments

TL;DR: The results of these determinations suggested that there was no drastic decrease in shelf denitrification rates at the end of winter off Pt. Barrow, Alaska, despite the fact that a supply of new organic material to the sediments via primary production had not occurred for several months as mentioned in this paper.

CH4 production via CO2 reduction in a temperate bog: A source of 13C-depIeted CH4

TL;DR: In this article, the rate of aceticlastic methanogenesis and CO2 reduction in peat soil, using (C-14)-labeled acetate and sodium bicarbonate, show that acetate was not an important CH4 precursor.

Role of a strong oxygen-deficient zone in the preservation and degradation of organic matter: a carbon budget for the continental margins of northwest Mexico and Washington State

TL;DR: The role of oxygen in the preservation of organic matter on a margin with a strong oxygen-deficient zone and on a typical western continental margin was investigated in this paper. But, the results were limited to the continental margins of northwest Mexico and Washington State.

Seasonal and spatial patterns of oxygen production, respiration and root-rhizome release in Potamogeton perfoliatus L. and Zostera marina L.

TL;DR: O 2 release from the rhizomes of Potamogeton perfoliatus L. was directly dependent on photosynthesis and that O 2 concentrations in sediments near the Rhizomes started to decrease within 2 min after plants were darkened, using Fick's first law of diffusion.
