Siberian Shelf Siberian Shelf The Siberian Shelf, one of the Arctic Ocean coastal shelves (such as the Milne Ice Shelf), is the largest continental shelf of the Earth, a part of the continental shelf of Russia. It extends from the continent of Eurasia in the general area of North Siberia (hence the name) into the Arctic Ocean. It stretches to offshore. It is relatively shallow, with average depth of 100 m. A number of islands are within the shelf, including the Wrangel Island, Novaya Zemlya, and the New Siberian Islands. It is encompassed by the Kara Sea, Laptev Sea, and East Siberian
Novaya Zemlya lost more than three-fourths of the merchant ships committed to the convoy — more than one fourth of the losses to American shipping in all convoys to northern Russia. The destruction of PQ-17 significantly affected the people dependent on supplies carried by the ill-fated merchant ships. Karlo Stajner, a Gulag prisoner in Norilsk in 1942, wrote “the German cruiser’s attack on Novaya Zemlya and the sinking of the food transports had catastrophic consequences…the population was left without provisions…supplies in the warehouses of Norilsk [were] distributed among the NKVD, the guards, and the few free civilians that lived in the town.”
