L作为自主仪器载体系统，用于研究底栖边界层的过程。它们通常部署在几百到6000米深的海底，超出了遥感和传统系统的探测范围。在以自由落体模式到达海底后，机载指挥系统开始深海实验。在任务结束时，一个声学命令释放压舱物的重量，着陆器凭借其正浮力上升到海面。20世纪70年代末，美国开发了自由车辆抓取式呼吸计（FVGR）和锰结核项目（MANOP）着陆器，迈出了成功开发深海自动驾驶车辆的第一步。第一个德国着陆器系统在1986年成功地部署在4500米深处。在20世纪90年代初，已经有大约30个着陆器系统在运行。同样在1990年代，国际着陆器发展的技术领先转移到欧洲，这使6个GEOMAR模块化着陆器编队排队等待部署。
L as autonomous instrument carrier systems, are used to study processes at the benthic boundary layer. They are usually deployed on the seafloor at depths of several hundred to 6,000 metres beyond the reach of remote sensing and conventional systems. After reaching the seafloor in a free-fall mode, an onboard command system starts the deep-sea experiment. At the end of the mission an acoustic command releases the ballast weights, and the lander rises by the virtue of its positive buoyancy to the sea surface. The first steps toward the development of successful deepsea autonomous vehicles were taken in the United States in the late 1970s by the development of the free vehicle grab respirometer (FVGR) and Manganese Nodule Project (MANOP) Lander. The first German lander system was successfully deployed at a 4,500-metre depth in 1986. In the early 1990s, there were already about 30 lander systems in operation. Also in the 1990s, the technological lead of international lander development shifted to Europe, which was benefiting A fleet of six GEOMAR modular landers lined up for deployment.
