Use of High-Resolution Seismoacoustic Methods for Monitoring the Position of Underwater Pipelines in Rivers and on the Sea Shelf

—The results of acoustic sounding of the routes of underwater pipelines obtained by the authors in a number of expeditions in river water areas and in the seas of the Arctic Ocean are considered. The possibilities of using narrow-beam parametric systems as a component of environmental monitoring are discussed. in areas buried under the bottom of underwater pipelines.
