- Unpredictable ice patterns affect the ability of beluga whales to migrate using their typical routes and increase the potential for becoming trapped in the ice. When this happens, belugas can suffer from a lack of prey and be more vulnerable to predators. In severe cases, they can run out of areas where they can come to the surface to breathe.

Belugas are known to migrate into areas historically covered with as much as 95 percent sea ice, where they must dive more than 1,000 metres to find food and resurface to breathe in an ever-shifting mosaic of cracks, holes and fractures in the ice.

An icebreaker is a class of ships that can break the thickest ice and easily travel where no other ships can, in higher latitudes, close to the Arctic. Icebreakers clear paths by pushing straight into frozen-over water or pack ice. The ice usually breaks without a noticeable change in the vessel’s trim. When the ice is thick, the ship can drive its...
After receiving three icebreakers (1954-1956), the Soviet minister of commerce asked a Finnish company named Wärtsilä in Finland to build even larger and stronger ships. One of these ships named Moskva was designed in 1956 and featured one of the most potent diesel-electric power plants ever installed on a vessel at the time. Moskva is the Russian ...
In December 1984, a hunter spotted a herd of up to 3,000 beluga whales in the Chukchi Peninsula’s ice-covered coastal waters. While happy at first – since belugas are nutritious and appreciated – the hunter and his group noticed something was wrong. The weather had created a 4m thick ice pack that had trapped the whales. Crossing the extended icy a...
One person on the vessel recalled that marine mammals react to music. And so music began to pour off the top deck. The crew played all kinds of music from pop to classical. After multiple experiments, the entrapped belugas started to react to classical music and approached the icebreaker. Using classical music, Moskva slowly herded the pod back to ...
