Abstract

Whenever the rate of supply of oxygen in natural waters cannot cope with its consumption rate in organic matter oxidation, redox gradients develop and reducing conditions occur. In the marine environment the most widespread systems exhibiting redox gradients are the upper layers of shallow water and continental shelf sediments. Under certain conditions of morphology, density stratification and organic matter supply the redoxcline may cross over into the overlying water column leading there to a more or less transient anoxic milieu (see for a review: Deuser, 1975, Grashoff, 1975). Fjords being connected to the open ocean by a shallow sill, often meet these preconditions.
