Paper Abstract

Ship accidents may cause containers and chemical pollutants to be released into the sea. For the recovery of a container or a non-mixing chemical on the seafloor, a fast and small- scaled location of such objects is an essential condition. Because of high turbidity in most coastal regions and the character and behavior of sinking chemicals, conventional video cameras are often unsuitable. Therefore, a new optical instrument is to be developed which allows the inspection of objects on the seafloor with range gated video images, and a detection of substances by remotely measuring fluorescence on the seafloor and in the water column. It will be applied as the payload of a remotely operated vehicle that is also equipped with other chemical and acoustical sensors for seawater analysis. Experiments in the laboratory have been carried out successfully, and first steps have been taken to realize a prototype. The submarine lidar is an instrument which allows to record contrast enhanced images of container son the seafloor, and to detect, locate, and classify the discharge of chemicals. Besides this application, it can be used for environmental monitoring, pipeline inspection, and oceanographic survey.
