Phosphorus binding by poorly crystalline iron oxides in North Sea sediments

Sediment pore water collection methods for trace metal analysis : a review

Quantification of Early Diagenesis: Dissolved Constituents in Pore Water and Signals in the Solid Phase

A chapter on the pore water of sediments and the processes of early diagenesis, reflected by the concentration profiles therein, can certainly be structured in different ways. One possibility is, for example, to start with the sample-taking strat egies, followed by the analytical treatment of the samples, then a model presentation to substantiate the processes, and finally a quantitative evaluation of the measured profiles with regard to material fluxes and reaction rates. The reader who would prefer this sequence is recommended to begin with the Sections 3.3, 3.4, 3.5 and to consult the Sections 3.1 and 3.2 later. However, in our opinion, marine geochemistry departed from its initial development stage of sample collection and anlysis some years ago. This book is therefore written with a different structure from earlier texts. The well understood theoretical knowledge on concentration profiles has to be introduced from the beginning.

Iron and manganese cycling in different sedimentary environments on the North Sea continental margin

A simple, inexpensive, and highly efficient centrifuge tube allows nearly complete extraction of interstitial water from coarse, sandy sediments with porosities as low as 32%. The method is fast (5 min), efficient (55–92% of the available water is obtained), reliable, and can be peformed on board ship at only 1,500 × g. The efficiency of the method permits a high sampling resolution (millimeter scale). The centrifuge tube is made of polyethylene and can be used for trace metal determinations after cleaning with acid. Due to a built-in filter, pore waters are clean and need not be filtered afterward, thus reducing the risk of contamination and possible oxidation artifacts.
