Abstract
The biogeochemistry of sediments is mostly confined to the upper part of the sediment. It is very rare to find biological processes of major importance in the geochemistry of sediments below a depth of half a meter. More often the major chemical changes take place at the uppermost centimetres of the sediments. In anaerobic sediments (sediments with the redoxcline at or above the sediment/water interface) biological effects on chemical transformations are usually restricted to even more shallow depths than with aerobic sediments. In the Baltic Sea anaerobic sediments are unconsolidated with a water content of 70% or more (Fig. 1). These sediments occur at various water depths but are mainly situated below the halocline, that is below about 55 m. The biogeochemistry of these sediments is being studied with the use of an in situ simulation technique. The experimental site is at a water depth of 10 m. This depth was chosen to facilitate the necessary SCUBA diving.
