In March 2021, public voting for names of new research vessels had been launched on website of Russian Ministry of Education and Science. Recently, the voting results were announced: the vessels will bear the names of two distinguished Russian scholars, Viktor Ilichev and Alexander Lisitsyn.
This paper presents an instrument based on an equal-arm Michelson interferometer and a frequency-stabilized helium-neon laser. It is designed to record hydrosphere pressure variations in the frequency range from 0 (conventionally) to 1000 Hz, with accuracy of 0.24 mPa at sea depths of up to 50 m.
Scientists have found evidence that frozen methane deposits in the Arctic Ocean – known as the “sleeping giants of the carbon cycle” – have started to be released over a large area of the continental slope off the East Siberian coast, the Guardian can reveal.
On May 29, 2020, due to a breakdown at a fuel storage tank at Norilsk-Taimyr Energy's Thermal Power Plant No. 3 (owned by Nornickel), more than 17,500 tons (21,000 cubic meters) of diesel fuel spilled into local rivers and onto the ground near Norilsk. The incident is one of the largest oil spills in the history of Arctic exploration. Images taken on May 31 and June 1 from the Sentinel-2 satellite show spots of oil product pollutions (red-colored water) that moved along the Ambarnaya River.
Complex expedition of Russian Academy of Sciences in the Atlantic sector of the Southern ocean nearly finished its final phase. The expedition staff and crew carried out complex gasgeochemical studies, observed anomalies and detected unusual phenomena. Now the expedition is heading for Kaliningrad. The researchers are planning to perform three hydrological stations up to 700-800 m deep near the Equator line.
