Novaya Zemlya under naval escort to deliver desperately needed Lend-Lease supplies to northern Soviet seaports. Destruction of the Allied convoys was thus a top priority for the German Navy — and brought World War II to Novaya Zemlya. The most ill-fated and one of the largest Arctic convoys, code-named “PQ-17,” left Iceland on June 27, 1942. It consisted of thirty-four merchant ships, six destroyer escorts, fifteen additional armed ships (among which were two Free-French corvettes), and three small rescue craft. The fast-moving convoy encountered ice floes on June 30 and was forced to reduce speed. On the following morning, the convoy was
Baltica belt of the Timanide orogeny and overlain by Mesoproterozoic sediments. The margin became a passive margin facing an Ural Ocean in the Cambrian-Ordovician. The eastern margin stretches south through the Ural Mountains from the northern end of the Novaya Zemlya archipelago. The margin follows the bent shape of Novaya Zemlya which was caused in the Late Permian by the Siberian Traps. It is clear from Baltic endemic fossils in Novaya Zemlya that the islands have been part of Baltica since Early Palaeozoic, whereas the Taymyr Peninsula farther east was part of the passive margin of Siberia in the Early Palaeozoic.
