Uranium in the oceans: Where it goes and why
TL;DR: In this article, it was shown that dissolution of manganese and iron oxides may be induced by the onset of sulfate reduction, which occurs relatively late in the diagenetic sequence.

The oceanic phosphorus cycle.

TL;DR: Research in the Pacific Ocean gyres indicates that biological P uptake rates far surpass the combined input from atmospheric and deep water sources, suggesting that P is efficiently recycled within oligotrophic euphotic zones.

The biogeochemistry of manganese and iron reduction in marine sediments
TL;DR: In this paper, the results of laboratory studies on the types of manganese and iron reduction that are known to occur in marine sediments, and then discuss the occurrence of these processes in different sedimentary environments.

The influence of microhabitats on the carbon isotopic composition of deep-sea benthic foraminifera
TL;DR: In this paper, a set of box cores from continental margin environments in the Atlantic and Pacific oceans were used to evaluate the importance of environmental (microhabitat) effects on the carbon isotopic composition of benthic foraminifera.

TL;DR: In this paper, the diffusion of O 2 fluxes through the diffusive boundary layer and the depth distribution of consumption rates within the sediment were calculated from the obtained microprofiles, and the difference correlated with the abundance of macrofauna in the sediment.

TL;DR: Pore water profiles of total CO 2, pH, PO 3−4, NO − 3 plus NO − 2, SO 2− 4, S 2−, Fe 2+ and Mn 2+ have been obtained in cores from pelagic sediments of the eastern equatorial Atlantic under waters of moderate to high productivity as mentioned in this paper.

Particulate organic carbon flux in the oceans—surface productivity and oxygen utilization
TL;DR: In this paper, an empirical relationship was established that predicts organic carbon flux at any depth in the oceans below the base of the euphotic zone as a function of the mean net primary production rate at the surface and depth-dependent consumption.

Geochemical Processes: Water and Sediment Environments
TL;DR: 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.

High precision determination of titration alkalinity and total carbon dioxide content of sea water by potentiometric titration
TL;DR: In this paper, the titration alkalinity At and the total carbon dioxide concentration Σ CO2 of a sea water sample can be determined by direct potentiometric titration.
