Lander (marine research)
A lander is an unmanned research device used to explore the deep sea .
Landers are set down on the seabed from on board a research vessel above the deployment site and are pulled to the seabed by ballast weights (so-called free-fall devices or bottom landers). Some devices can also be dragged to the point of use and then set down. For buoyancy after the measurements are finished, the weights are triggered acoustically and the device floats to the sea surface with the help of buoyancy balls, where it is picked up again by the research vessel. They are autonomous carrier systems and can be used to measure and record values and to hold samples. They can be used up to a depth of 6000 meters (or more as with Limiting Factor ).
The first German deep-sea lander was deployed in 1986 by the research vessel Meteor in the North Atlantic and was in service until 1991.
