  The Arctic Archipelago
The remains of the last ice age are seen in the Canadian Arctic Archipelago in ice caps that occur on Baffin (Penny and Barns ice caps), Devon, Axel Heiberg (Franz Műller Ice Cap) and Ellesmere (Prince of Wales, Sydkapand and Agassiz and an unnamed ice cap).
The bedrock geology of the Canadian Arctic Archipelago consist largely of a metamorphic Precambrian bedrock composed of mainly granite and gneiss and of a lower Paleozoic sedimentary rock composed of a major calcium carbonate complex (Dyke 1984, Edlund and Alt, 1989).
Drawing on his experiences in Alaska, growing up in Greenland, and fieldwork in the Arctic Archipelago he stated that to the most northerly tribes (ones living in the Archipelago) the use of vegetable food is purely incidental and largely limited to the partly fermented and pre-digested content of the rumen of caribou and muskoxen.

 Modern Bathymetric Data Base for the Arctic Workshop, Submitted Abstracts, Appendix 5
The Arctic Ocean is the least known of all the ocean basins.
SE PMGRE encourages the idea to compile the Arctic bathymetry digital data base as an important contribution to geological-geophysical study of the region and also in connection with the need to approach delimitation of the coastal states' shelf zones on the basis of unified cartographic approach.
In general, the operation areas are the Arctic during the northern summer and the Antarctic during the austral summer.

 Weather in the Arctic - All Things Arctic
The main climate constant in all Arctic areas is the extreme fluctuation of incoming solar radiation.
The Arctic is a major source of very cold air that moves toward the equator, meeting with warmer air in the middle latitudes and causing rain and snow.
In many Arctic and subarctic regions, the weather is controlled by semipermanent low pressure systems that are weakly developed in summer, but stronger in winter.

 Canadian Arctic Archipelago - Wikipedia, the free encyclopedia
The archipelago extends some 2 400 km longitudinally and 1 900 km from the mainland to Cape Columbia, the northernmost point on Ellesmere Island.
It is bounded on the west by the Beaufort Sea; on the north by the Arctic Ocean; on the east by Greenland, Baffin Bay and Davis Strait; and on the south by Hudson Bay and the Canadian mainland.
The climate of the islands is arctic, and the terrain consists of tundra except in mountainous areas.

 CARC - Northern Perspectives (Volume 22, Number 4, Winter 1994-95)
Canada's claim to sovereignty over the waters of the Arctic Archipelago stands or falls on whether the drawing of straight baselines enclosing the waters as internal waters can be justified in law and on whether the waters of the Northwest Passage constitute an international strait.
In short, the preponderant view of legal authorities is that the waters of the Canadian Arctic Archipelago are properly enclosed by straight baselines and are the internal waters of Canada.
The term "waters of the Canadian Arctic Archipelago" refers to the water between the islands of the archipelago and not to the waters in the open seas of the Beaufort Sea and the Arctic Ocean to the west or to the waters of Davis Strait and Baffin Bay to the east.

 Arctic Climate: A Primer
The arctic climate is characterized by high spatial variability, and includes both polar maritime (influenced by the ocean) and continental (influenced by large land masses) climate subtypes.
The main constant is that the climate in all arctic areas is affected by the extreme solar radiation conditions of high latitudes.
For example, the amount of solar radiation received in summer along the Siberian arctic coast compares favorably, by virtue of the long period of daylight, with that in lower middle latitudes.

 Life in the Arctic labyrinth Natural History - Find Articles
On a freezing September night, the ship was stopped and silent in shifting pack ice at the heart of Canada's Arctic Archipelago, the 550,000-square-mile labyrinth of islands, bays, sounds, gulfs, peninsulas, inlets, channels, and straits north of the North American mainland.
The Arctic Archipelago is less studied than the remotest parts of Antarctica.
The Arctic Ocean is the opposite: a sea shut in by the landmasses of Siberia, North America, and countless islands.

There are a number of areas on the western islands of the Alexander Archipelago that appear to have escaped being overridden by glacial ice during the late Wisconsin.
Recent studies from western Greenland (Willemse and Törnqvist, 1999) indicate that LOI organic carbon content values in arctic lakes are strongly correlated with the duration of ice cover, and therefore annual average temperature, suggesting colder conditions may have prevailed during the low LOI organic carbon phases.
This indicates that river contribution to the Arctic Ocean and glacier contribution to the Arctic Ocean are intimately related to each other and to climate change, but determining the extent of the interplay of these variables will require further study.

 Seismic Arctic Earthquakes G.P. Avetisov.
The picture of the earthquake focal distribution in the Arctic and their number turned out to be unexpected for the authors and caused an attempt made by D.I.Mushketov (1935) to explain it for the first time accounting them to intensive contemporary uplifting and subsiding.
Summaries of the Arctic earthquakes are given in publications by B.Gutenberg and K.Richter with regard to the Earth¸s seismicity (1948; 1954), the latter presenting a catalogue and a map indicating magnitudes and precision of the location.
A catalogue and a map of 281 Arctic earthquakes over the period of January 1955 to March 1964 was presented in the paper by L.Sykes (1965) published in the same year basing on the computer determinations and re-determinations of epicentral locations.

 The Arctic: the ocean, sea ice, icebergs, and climate
Much of the Arctic seasonal variation in ice cover can be found in the Bering Sea (mainly adjacent to the continents, and south to the Aleutian Islands), and in the Sea of Okhotsk, as far south as 42ºN, near Hokkaido, Japan.
There is some evidence that the Arctic sea-ice cover has decreased about 6% during the last two decades, and that the mean ice thickness has decreased as well.
The Arctic Basin receives a large amount of fresh water from the large rivers on the surrounding continents (mainly the MacKenzie in Canada and the Ob, the Yenisey and the Lena in Siberia), and during the short summer these freshwater sources spread out over large areas.

For instance, levels of cadmium and lead in the liver of Arctic char from a high mountain lake were comparable to those of fish from waters receiving metal-polluted industrial effluents.
The research and training being conducted with Inuit in the Canadian Arctic Archipelago builds on two years of preliminary work, funded primarily through the Austrian Ministry of Education, Science and Culture, with much-needed support from the Polar Continental Shelf Project as well as the Northern Contaminants Program of Indian and Northern Affairs, Canada.
The researchers hope that increased funding for the training and research activities in the Canadian Arctic can be expanded to include many more Inuit participants and communities within the Archipelago, as well as a broader geographic cross-section of Archipelago lake ecosystems and char populations.

 NOVA | Arctic Passage | Future of the Passage | PBS
In recent years, in the wake of scientific reports of rapid melting in the Arctic, some have taken to declaring that the fabled Northwest Passage, sought for centuries by mariners and merchants, will soon be open for shipping, shaving thousands of miles off trips that would otherwise have gone through the Panama Canal.
To many Arctic experts, such claims are at best overstated—one said the CARC letter "takes the Canadian cake for exaggeration"—at worst irresponsible.

Salicaceae pertains to the shrubs and trees of the willow family of the Canadian Arctic Archipelago.
The soil where the catkins grow is barely discernible on the tundra because of its cover by a constant layer of mosses and lichens, through which other herbaceous and shrubby plants grow like the catkins.
All classes in the willow family are either shrubs or trees with alternate leaves, small greenish to yellowish flowers with the fruit capsule and with seeds.

 Archaeology of the Tundra and Arctic Alaska
In an area stretching along the coastline from Bristol Bay and the Alaska Peninsula, along the Bering Sea and Chukchi Sea coasts, northward around Alaska, and eastwards across the arctic all the way to Greenland, the coastline is ice-bound in winter and the terrain is generally treeless.
Subsequently, it has been found throughout the Tundra and Arctic Zone that is characterized by coasts that are ice-bound in winter and treeless hinterland, from the Bering Sea side of the Alaska Peninsula, northward along the coast and throughout the Brooks Range, and eventually, along the Canadian Arctic coast and the Arctic Archipelago to Greenland.
Some investigators feel that the Arctic Small Tool tradition marks the arrival of the ancestral Eskimo cultures while many others feel that, although there appears to be some technological continuity, the ancestral development of the historic Eskimo cultures took place in Siberia and the islands of the Bering Sea at a much later date.
