Benthic lander

[2] However, divers have a very small range of depth and a short time under water and cause a large disturbance to the sea bed, thereby introducing more error into the measurements.

[2] These shortcomings are improved by using benthic landers as they have a much larger depth and time capacity than divers and can be designed to cause minimal disturbance to the sea floor.

[2] Some common uses for the collected seabed data include studying currents, tides, and microseismic and magnetic field activity and monitoring marine life.

Longer duration mission landers are typically equipped with ultrasonic sensors, LiDAR, and cameras in order to intelligently navigate the seabed.

[3] Additionally, depending on what measurements the mission is intended to take, the lander can be configured to disrupt the environment in different ways enabling for higher precision of certain data sets at the tradeoff of others.
