Autonomous bottom landers
Study processes at the seafloor by incubation technique
Biological, chemical, and physical processes at the seafloor play an essential role to sustain ecosystem functioning of aquatic environments. In-situ incubations of sediment with overlying water provide consistent information on sediment-water solute exchanges and make it possible to do controlled experiments and simulate environmental changes. Making the measurements and experiments directly at the seafloor avoid artifacts created by bringing samples to the surface, including shaking, changes in pressure, temperature, light, oxygen, etc.
This application note presents four types of autonomous landers that all make sediment-water incubations at the seafloor.
