The benthic lander is a multi-purpose device for deploying passive samplers for sediment monitoring. The lander consists of a modular tripod frame capable of deploying up to three benthic flux chambers or a sediment flux profiler.
Deployment
The benthic lander is deployed by line using a light crane or winch from the vessel. The spread footings on the tripod legs support the tripod on the soft seabed, while the center post guides the self-weight penetration of the flux chambers/profiler into the sediments.
The position on the seabed may be marked using a float or small bouy and a secondary anchor to avoid disturbing the lander.
