Research Results on Ecological Hazard Objects in Abrosimov Bay (Novaya Zemlya, Kara Sea)

Abstract—The article presents results of field research on environmental assessment in Abrosimov Bay (Yuzhny Island of Novaya Zemlya) in connection with the existing RW disposal sites in this region. In the course of the studies, technology was created based on the original remotely and unmanned towed underwater vehicles (ROV and TUUV), as well as special side scan sonar (SSS). To specify the state of radioactive and operational waste immersed in Abrosimov Bay in 1960s, the oceanological TUUV Videomodule was used. This vehicle was developed at IO RAS and is capable of in situ research on local benthic communities, as well as the microrelief of the ocean floor. The research done in Abrosimov Bay using the new technology made it possible to identify underwater objects whose origin and location were previously in doubt.
