The Arctic Ocean in the Paleocene and early Eocene epoch did not exist in its present form, although the individual deepwater sea basins (Canadian Basin, Makarov, Amundsen and Nansen) did already exist. The far north was covered with subtropical and tropical vegetation land (and here). It was separated from the elevated areas of the modern Greenland, Norwegian, Barents and North Seas and much of Northern Europe and the European part of Russia, from Asia, the Kara Sea, Laptev Sea, West Siberian Plain and from North America (Canada and Alaska) and the modern Canadian Basin of the Arctic Ocean, the Beaufort Sea, Baffin Bay and Labrador and the lowlands of northern Canada. It was connected with Asia by the land bridge ridges Alpha Mendeleev University and Svalbard - Franz Josef - Severnaya Zemlya, and to North America by the land bridge located at the Queen Elizabeth Islands.
The Greenland-European sea basin formed at the beginning of the Eocene epoch (58-55 million years ago). In the Paleocene epoch (66 to 58-55 million years ago), the Greenland, Norway and Lofontenskaya basins represented land. Much of Europe was isolated marine basins within which there weas only the small area of Belgium, France and the Volga region. The single continent of Hyperborea covered the western half of the Arctic Ocean between Greenland and Europe and northern Europe itself.
At the beginning of the Eocene epoch, the sinking the Greenland and Norwegian Lofontenskoy basins below sea level caused them to be flooded with water, and what was land became a large sea, located within the continental crust. Its depth varied from a few meters in the Early Eocene epoch (55-50 million years ago) to more than 2 km in the late Oligocene - early Neogene period (34-30 million years ago).
At the same time, a shallow marine basin covered much of Europe and the European part of Russia. During the Eocene epoch Hyperborea was connected to the east of the Western Siberian group of seas at the South Urals. The Greenland-European sea basin existed before the Miocene epoch of the Neogene period (22 million years ago), but it was shallow and at times was dry land.
The West Siberian sea basin is a huge shallow sea, also located on the continental crust, which has existed since the early Paleogene in the Paleocene, Eocene, and probably early Oligocene ages (66 to 34-30 million years ago) and extends through the Turgay Sea Strait to the southern part of the Eastern European and Tarim Basins offshore. The latter was located adjacent to Tibet on the Kunlun/Tarim continental block where the modern Taklamakan and Gobi deserts are today. In Oligocene time, the uplifting of Western Siberia turned it into dry land with a chain of closed lakes and wetlands in its central part.
The Canadian marine basin has existed since the end of the Mesozoic Era. During the Paleogene it was a deep-sea basin with oceanic crust but had a shallow sea on the northern continental margin of Canada (between p. McKenzie and Hudson Bay) , and formed at the end of the Lower Cretaceous epoch (from 110 million years ago) and Baffin Labradoskuyu basin with oceanic crust, located on the site of the same name.
A paleotemperature reconstruction was conducted by different researchers using flagellar siliceous algae and spore-pollen complex which indicates the Paleocene and probably the early Eocene was a time of tropical climate. This changed in the mid-late Eocene epoch to a sub-tropical climate and in the Oligocene became a moderately warm climate.

Warm sea basins (subtropical or warm temperate) remained until about the Middle Miocene (about 16 million years ago).
