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.

Production of N 2 through Anaerobic Ammonium Oxidation Coupled to Nitrate Reduction in Marine Sediments
Bo Thamdrup,Tage Dalsgaard +1 more
TL;DR: It is found that a process novel to the marine nitrogen cycle, anaerobic oxidation of ammonium coupled to nitrate reduction, contributes substantially to N2 production in marine sediments.

Rhizon sampling of porewaters near the sediment‐water interface of aquatic systems
Jens Seeberg-Elverfeldt,Jens Seeberg-Elverfeldt,Michael Schlüter,Tomas Feseker,Martin Kölling +4 more
TL;DR: In this article, a newly developed Rhizon in situ sampler (RISS) is presented for porewater sampling from sediments in aquatic systems and the results revealed that horizontally aligned Rhizons can sample pore water with a vertical resolution of 1 cm.

Robert W. Collier,John M. Edmond +1 more
TL;DR: In this paper, a series of physical and chemical leaching-decomposition experiments were conducted to identify the major and trace element composition of the biogenic particulate matter of plankton.

Ferrozine---a new spectrophotometric reagent for iron
TL;DR: The ferroin group has been known to react as bidentate ligands with certain metal ions such as ferrous, cuprous, and cobaltous, to give colored complex species.
Journal ArticleDOI
Spectrophotometric determination of hydrogen sulfide in natural waters1
TL;DR: Winkler and Carpenter as mentioned in this paper proposed a modification of the Winkler method for the detection of dissolved oxygen in seawater, which has been shown to be more accurate than the original method.

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.

Early oxidation of organic matter in pelagic sediments of the eastern equatorial Atlantic: suboxic diagenesis
Philip N. Froelich,Gary P. Klinkhammer,Michael L. Bender,Nile A. Luedtke,G.R. Heath,Doug Cullen,Paul Dauphin,Doug Hammond,Blayne Hartman,Val Maynard +9 more
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.

Diffusion of ions in sea water and in deep-sea sediments
Li Yuan-Hui,Sandra Gregory +1 more
TL;DR: The tracer diffusion coefficients of ions in deep-sea sediments, Dj,sed., can be related to Dj∗ by as mentioned in this paper, where θ is the tortuosity of the bulk sediment and a constant close to one.
