This presentation will describe experiences learned from use of Gothenburg University benthic chamber landers during more than 300 deployments/1000 incubations in water depths from 5 to 5600 m. Measurements of different solutes/contaminants will be presented as well as manipulative injection experiments to study the N-cycle, phosphate retention and the effects of sediment re-suspension. Methods to increase the data quality will also be discussed.
