Mikhail Somov
Whilst attempting to reach Edgeworth David base in the Bunger Hills early in January 1987 Nella Dan encountered heavy pack ice and became beset on 8 January. On 13 January she received an InmarSat telephone call from Mikhail Somov, an ice-strengthened Soviet Antarctic resupply vessel which happened to be nearby and also en route to Bunger Hills. Still beset and with no immediate hope of release from the now rafting pack ice, Nella Dan accepted an offer of assistance from Mikhail Somov.

The research and expedition vessel Mikhail Somov has returned to Arkhangelsk after its last Arctic voyage of the current navigation season, said the press service of the Northern Inter-Regional Territorial Board for Hydrometeorology and Environmental Monitoring (Sevhydromet).
“The trip lasted just over a month. The vessel sailed from Arkhangelsk to Dikson and back. Vitally important consignments were delivered to 18 meteorological stations on the coast and islands of the White and Barents Seas and to some stations in the Kara Sea. About 700 tons of general cargo, including fuel, food, clothing, tools, instruments and construction materials, have been delivered to meteorologists,” the press service said.
