Russian Oil Tanker Suffers Major Hull Damage In Arctic Despite Icebreaker Escort En Route To China
A major incident in the Arctic highlights the escalating risks of maritime transport in challenging conditions. Recent reports confirm substantial hull damage to a Russian oil tanker en route to China, despite the presence of an icebreaker escort. This event echoes last year’s entrapment of the tanker *Lynx* in the East Siberian Sea, carrying approximately one million barrels of crude.
Mid-frequency acoustic transmission and communication in the Arctic: the Nansen Basin under-ice experiments
The Arctic Ocean's rapidly changing environment necessitates robust measurement and monitoring capabilities, often relying on acoustic communication under ice cover. This paper presents validated data from under-ice acoustic transmission experiments conducted in the Nansen Basin (August 2019 and March 2023), revealing complex signal propagation influenced by oceanographic ducts and water depths. Measured impulse responses, ranging from 8 to 42 nautical miles, demonstrate the interplay of direct, surface-ducted, and bottom-reflected paths.
