The Arctic Ocean:
The Great Transport had left humanity in a very bad state. What was left of the United States, now a bunch of scattered Northern Alaskan settlements led by Fairbanks, was trying its best to move downwards to find habitable lands. Eventually they found some in the form of the Columbian coast, and they settled it in the hopes of gaining new growth. They were outmatched, however, by Canada, which was also reduced to its forgotten areas. However, they resettled the areas with ease, restarting the farming the prairies contributed as well as constructing settlements around the great Lakes and St. Lawrence, including their new capital Maple City, located at the meeting point of Lake Superior and Huron.
Across the Davis Strait, the Inuits of Greenland finally found themselves independent at the cost of their capital and southern settlements. After resettling the area rather quickly, a government was reformed in Ittoqqortoormiit, and the Inuits got around to establishing settlements around them, such as the shores of Lake Melville, northern Newfoundland, Ireland and Iceland, the latter of which was split with Norway.
Like the North Americans, Norway was struggling to survive. The 2,939 citizens, miners, meteorologists and radio communicators non-permanently residing in Svalbard and Jan Mayen found themselves isolated and cut off from Oslo and the Norwegian Mainland, and they turned to themselves to survive, as well as escape for the lower, much more fertile and habitable land in Europe. Eventually, contact was reestablished with the Norwegian mainland, though only from the town of Tromsø, which was the only major Norwegian settlement left after the rest were wiped out. After reestablishment, the Norwegian state began resettling the rest of the Norwegian coast, as well as Establishing posts around northern Britain, the Rhine Delta and western Brittany. Eventually some of the British Outposts, tired of the very few resources coming from Tromsø, started campaigning for independence.
The Russians, however, were in a better shape than the other remnants of humanity. Now being run from Novosibirsk, they had lots of land left to reestablish Russia as a world superpower, as well as enough people to extract resources and expand the Russian boundaries to the Pacific coasts and the Fertile wilderness that lay ahead of them. In no matter of seconds, Outposts to the Amur River and the Black Sea, as well as across to the Baltic Sea were established. All in all, Russia is now the global power of the world, rivalling only Canada for dominance over the remaining resources.
