The Arctic- The Arctic region is a unique area among Earth's ecosystems. Arctic tundra occurs in the far Northern Hemisphere, north of the taiga belt.The word "tundra" usually refers only to the areas where the subsoil is permafrost, or permanently frozen soil. (It may also refer to the treeless plain in general, so that northern Sápmi would be included.) Permafrost tundra includes vast areas of northern Russia and Canada. The polar tundra is home to several peoples who are mostly nomadic reindeer herders, such as the Nganasan and Nenets in the permafrost area (and the Sami in Sápmi).
The Circle itself passes through eight countries. Canada, Finland, Greenland, Iceland, Norway, Russia, Sweden, United States. Denmark which represents Greenland, and the Faroe Islands is a member of the Arctic Council. The cultures in the region and the Arctic indigenous peoples have adapted to its cold and extreme conditions. Very few people live north of the Arctic Circle due to the cold conditions. The three largest communities above the Arctic Circle are situated in Russia; Murmansk (population 325,100), Norilsk (135,000), and Vorkuta (85,000). Tromsø in Norway has about 62,000 inhabitants, whereas Rovaniemi in Finland—which lies slightly south of the line—has slightly fewer than 58,000.
The Circumpolar North or Arctic generally includes the lands surrounding the Arctic Circle and these indigenous peoples. Evenks, Inuit, Greenland, Northern Canada (Nunavut and Northwest Territories), Alaska, Chukotka (Russia) , Koryaks, Nenets, Khanty, Chukchi, Sami Northern Norway, Sweden, Finland, and Kola peninsula in Russia and Yukaghirs.

The Peregrine Falcon
), also known simply as the Peregrine
, and historically as the "Duck Hawk" in North America, is a cosmopolitan bird of prey
in the family Falconidae
. It is a large, crow-sized falcon
, with a blue-gray back, barred white underparts, and a black head and "moustache". As with other bird-eating raptors, the female is bigger than the male. Authorities recognize 17–19 subspecies
, which vary in appearance and range; there is disagreement over whether the distinctive Barbary Falcon
is a subspecies or a distinct species
The Peregrine's breeding range includes land regions from the Arctic tundra to the Tropics. It can be found nearly everywhere on Earth, excepting extreme polar regions, very high mountains, and most tropical rainforests; the only major ice-free landmass from which it is entirely absent is New Zealand. This makes it the world's most widespread bird of prey. Both the English and scientific names of this species mean "wandering falcon", referring to the migratory habits of many northern populations.

After graduating from the U.S. Naval Academy in 1867, Sebree was posted to a number of vessels before being assigned to a rescue mission to find the remaining crew of the missing Polaris in the Navy's first mission to the Arctic. This attempt was only a partial success—the Polaris crew was rescued by a Scottish ship rather than the US Navy—but this led to Sebree's selection eleven years later for a second expedition to the Arctic. That mission to rescue Adolphus Greely and the survivors of the Lady Franklin Bay expedition was a success. Sebree was subsequently appointed as the second acting governor of American Samoa.
