1957
 First ultra-abyssal reserch. Life found at depths exceeding 7 km

1990s Six new species of benthic fauna were discovered using deep-sea submersibles Mir 
1997 Mirocaris sp. shrimps found on the Mid-Atlantic Ridge and named after submersibles Mir
2007-2016 Six expeditions to the Kara Sea and the Laptev Sea were conducted to investigate the ecosystems’ state. New data on the current abnormally warm conditions in the Arctic
