Deep-sea moorings, used to collect data and samples at fixed positions over long time periods, have increased use with the collecting of particles for biological and chemical analyses. Costs and efforts in the design, deployment, and recovery of deep-sea moorings are considerable, but significant results can be obtained that are not attainable otherwise. Moorings are difficult to retrieve because of difficulties in determining their exact position and release from the seabed. This paper describes an investigation of fundamental problems by using the manned submersibles Mir I and Mir 2 embarked on the Russian R/V Akademik Mstislav Keldysh. The exact position of the moorings on the seabed and the reasons for their failure to release were determined.
