Abstract
Mineralization reactions can take place in sediments along different aerobic and anaerobic pathways. The recent introduction of microelectrodes for ecological research has enabled the determination of oxygen and sulphide gradients in situ in the sediment. These micro-gradients give insight into the actual mineralization reactions taking place, and changes in these reactions can now be rapidly recorded. This paper describes the use of microelectrodes in the field in Lake Grevelingen. The effect of dam building on oxygen and sulphide microgradients and on mineralization reactions will be discussed.
