The hypothesis that reducing conditions exist in localized zones of high organic matter,
termed microniches, was first suggested over a century ago, but only relatively recently have …

Different mobilization mechanisms control the metal distribution in surface sediments of the
Belgium coastal zone (BCZ) and the anoxic Gotland basin (GB). This mobilization was …

In productive coastal sediments the separation between different biogeochemical zones (eg
oxic, iron (III)-reducing and sulfate-reducing) may be on the scale of millimetres …

Pollutions of trace metals (TMs) in reservoirs are blooming due to TMs were trapped
efficiently in reservoir sediments by dams. Despite the mobilization of TMs in sediments …

The DET (diffusive equilibrium in thin films) technique is developed to measure soluble
reactive phosphate (SRP) profiles in sediment pore waters at a millimetre resolution. The …

Authigenic pyrite preserves non-biomineralized tissues in the fossil record under
exceptional circumstances. Diagenetic models and taphonomic experiments demonstrate …

Faecal pellet deposition and bioturbation may lead to heterogeneously distributed particles
of localized highly reactive organic matter (microniches) being present below the oxygen …

The stability of sedimentary metal profiles (defined as the absence of significant changes in
profile shapes or concentrations as the accumulated metals are progressively buried), or the …

Abstract Spherical (~ 2 mm diameter) diatom (Skeletonema sp.) aggregates, representing
analogues of “marine snow”, were placed at the sediment–water interface of an …

The two dimensional, small-scale, distribution of labile trace metals was investigated in a
sandy loam soil historically treated with sewage sludge. After deployment of two DGT …
