Baltica data makes it difficult to locate the margin in the Arctic. Ordovician faunas indicate that most of Svalbard, including Bjørnøya, was part of Laurentia, but Franz Josef Land and Kvitøya (an eastern island of the Svalbard archipelago) most likely became part of Baltica in the Timanide Orogeny. The Taymyr Peninsula, in contrast, never was part of Baltica: southern Taymyr was part of Siberia whilst northern Taymyr and the Severnaya Zemlya archipelago were part of the independent Kara Terrane in the early Palaeozoic. The eastern margin, the Uralide orogen, extends from the Arctic Novaya Zemlya archipelago to the Aral Sea. The
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.”
