Underwater Automatic Sampling System
The Benthic Lander is an autonomous seabed observation platform designed for long-term deployment on the seafloor to measure in-situ physical, chemical, and biological parameters. These devices are widely used in deep-sea research to collect high-precision seabed data without disturbing the environment.
Equipment Overview
The Benthic Lander typically consists of a sturdy metal frame equipped with various scientific instruments, such as a Conductivity-Temperature-Depth (CTD) sensor, dissolved oxygen sensor, sediment collector, camera system, and acoustic release units. These devices can be modularly configured to meet different research needs and adapt to various marine environments.
