Expedition reveals underwater radioactive waste sites in the Arctic, suggesting impacts on ecology and hydrological measurements.
The information reports on the organization, conduct and main results obtained during expedition 97th of the RV “Akademik Mstislav Keldysh” to the Kara Sea on 01.09-06.10.2024. The purpose of the expedition is to study the state of underwater radioactive waste burials and ecology in the bays of Novaya Zemlya and the Novaya Zemlya Depression. In addition to traditional oceanographic instruments, underwater towed and remote-operated vehicles equipped with video, sonar and gamma-ray spectrometry equipment were used to conduct research. The work was carried out on board the RV, and in shallow water from a ship's boat. Benthos and bottom sediment samples were taken, as well as hydrological measurements. For the first time, burials of a number of objects have been confirmed, as well as detailed information about known objects using stereo imaging was obtained.
