The bioturbated zone of marine sediments is a region having a complex, time-dependent
geometry of diffusion and chemical reactions. It is possible to simplify this geometry by …

One important reaction which affects dissolved NH4+ distributions in marine sediments is
reversible adsorption on sediment solids. We investigate both the temperature dependency …

Abstract Iodine-129 (t 1 2, 16 My) is a naturally-occurring tracer which can be used to study
hydrologic and geologic processes on time scales up to 100 My. The pre-bomb atmospheric …

The two cosmogenic isotopes 129I and 36Cl have half-lives and geochemical
characteristics that make their application of interest in the tracing of crustal fluids, oil field …

Publisher Summary This chapter focuses on diagenetic processes near the sediment–water
interface of Long Island Sound (LIS). Analysis of the solid phase in this study shows …

The value of the pre-bomb 129I/127I ratio in the hydrosphere is important for the use of this
isotope system for dating and tracing purposes. In order to determine this value and to …

Nineteen sediment cores from the Madeira, Seine, Tagus and Nares Abyssal Plains and the
Alboran Sea have been used to evaluate the speciation, fluxes and diagenesis of iodine in …

Presented here are halogen concentrations (Cl, Br and I) in pore waters and sediments from
three deep cores in gas hydrate fields of the Nankai Trough area. The three cores were …

Chloride to bromide ratios were determined for rainfall in Western Australia and
groundwaters and surface waters from a number of catchments in Western Australia, Victoria …

Two cores from a NE Atlantic pelagic clay area of low accumulation rate each contain a
single turbidite with different age, thickness and composition. Diagenesis following …
