Early diagenesis in sediments from the eastern equatorial Pacific, II. Pore water metal results
TLDR
The results from these four sites suggest that the pore water profiles of these metals are controlled by processes involving the major oxidants (O2, NO3−, Mn and Fe oxides) as discussed by the authors.About:

Dissimilatory Fe(III) and Mn(IV) reduction.
TL;DR: The physiological characteristics of Geobacter species appear to explain why they have consistently been found to be the predominant Fe(III)- and Mn(IV)-reducing microorganisms in a variety of sedimentary environments.

Comparison of Atlantic and Pacific paleochemical records for the last 215,000 years : changes in deep ocean circulation and chemical inventories
Edward A. Boyle,Lloyd D Keigwin +1 more
TL;DR: In this article, detailed Cd/Ca and δ 13 C data have been obtained for benthic foraminifera from western North Atlantic and Equatorial Pacific sediment cores, which indicate that bottom waters overlying the Atlantic site have been nutrient depleted relative to those at the Pacific site over the last 215,000 years.
Journal ArticleDOI
Early diagenesis in differing depositional environments: The response of transition metals in pore water
TL;DR: In this article, the cycling of Fe, Mn, Ni, Co, Cu, Cr, V, and Mo during early diagenesis was investigated in sediments from five different depositional environments in the California Borderland.
Journal ArticleDOI
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.

Measurement of the apparent dissociation constants of carbonic acid in seawater at atmospheric pressure1
TL;DR: The apparent dissociation constants of carbonic acid in seawater were determined as functions of temperature (2-35°C) and salinity (19-43%) at atmospheric pressure by measurement of K'1 and the product K', K' as discussed by the authors.

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.
