The Xiamen Symposium on Marine Environmental Sciences (XMAS 2025)

Biological, chemical and physical processes at the seafloor plays an essential role for aquatic environments. In-situ incubations of sediment with overlying water provide valuable and consistent information on sediment-water solute exchanges. This presentation will describe experiences learned from use of Gothenburg University benthic chamber landers during more than 300 deployments/1000 incubations in water depths ranging from 5 to 5600 m. Measurements of different solutes/contaminants will be be presented as well as manipulative experiments to study the effects of hypoxia and anoxia, the N-cycle, phosphate retention and the effects of sediment re-suspension. Methods to increase the quality of the incubations will also be discussed.
