The Role Of Beringia In The Arctic Geography

The tundra is by far the coldest type of biome, as it is known for its low temperatures, little precipitation, poor nutrients, and short growing seasons. Occurring primarily near the Arctic within the Northern Hemisphere, the soil may be frozen all year up to a few feet, which allows no tree growth. However, a few animals have adapted to these conditions. These animals include lemmings, hares, oxen, foxes, wolves, and more. Within the tundra biome there are two different types of tundra biomes, arctic tundra and alpine tundra.

Faith & Surovell offer hopes for further testing for biological and spatial histories of individual species and their migrations in relation to climate, ecology, and human permeation. They state this will uncover which if not all of the three main mechanisms: climate change, overkill, and extraterrestrial impact, caused the North American mammal extinctions in the late Pleistocene (Faith and Surovell, 2009).

First, sediment samples and animal remains from the Bering Sea prove that the Beringia was habitable at the height of the ice age or 21,000 years ago. According to Elias: “humans did not survive the last ice age’s peak in northeastern Siberia, and yet there is no evidence they had reached Alaska or the rest of the New World either” (Elias). At this point, Elias’s theorizes that people lived on the Beringia, a 600 mile wide area between Siberia, Russia, and Alaska. Furthermore, “sediment cores” (Elias), from the Bering sea indicate that the

What is the federal government’s strategy to support its claims to sovereignty in the high Arctic?

This problem could mark either the end of human civilizations or mark the beginning of the next era of human development. It would decide on our species survival, whether there will be another mass extinction like the one 65 million years ago. The question is “How might the breaking up and melting of continental ice in Greenland and the Antarctic affect Canada’s coastline?”. In the following sections, we have gathered an abundance of information from a variety of sources from which we will discuss, and analyze. We will find out how this data can help us understand the effect of melting glaciers on Canada’s coastline, as well as how and what we could do to stop or slow it down.

In "Arctic National Wildlife Refuge: Seasons of Life and Land" former President Carter tells American conservationists of the importance of the Alaskan refuge. Carter explains that he is passionate about the preservation of the area and what he has done to protect it and the animals that inhabit the tundra. Using language to paint a beautiful scene and explain personal accounts, the former President shows conservationists all over America that he is on their side.

The Siberian tundra is basically melting away overtime, even though it has been frozen for tens of thousands of years. At such a fast rate it is speculated that it is influencing global warming. The landscape is changing fast. In the last three to four years, the underlying

The boime I’m going to do my report on is the tundra. The tundra is located near the north and south poles of the Earth. Two examples are the top of Russia and Greenland, but there are many more. It is an cold and barren place. Places that have civilization have a couple towns every now and then but, most of it is large plains of snow.

Since the 16th century, the Bering Strait region has been viewed as the likely route of travel from the Old World to the New World. Paleoindians moved into North America beyond the Bering Land Bridge between Eastern Siberia and present-day Alaska during the Late Glacial Maximum (LGM) when sea levels were significantly lowered due to the Quaternary glaciation. (Rivals & Semprebon, 2012, pg. 1608-1609). Pleistocene animals grazed their way through ice-free corridors, water logged routes, across Beringia and into Siberia, leaving footprints in the dry land in which hunter gatherer Paleoindians

In Greenland and in the Arctic I was astonished to see that ancient glaciers are rapidly disappearing well ahead of scientific predictions. All that I have seen and learned on this journey has terrified me. For decades, scientists have struggled to get the same basic message across: global

Environmental change in the Arctic has been a subject of recent interest within the discourse of global warming, climate change, and indigenous rights; however, scholars have yet to examine the importance of 20th century racial, cultural, and environmental interactions within Northern Canada. Specifically, the Northern areas of Ontario, Quebec, and Manitoba provide interesting and important issues that are critical to current discussions of global warming, climate change, and water rights and quality because of their location to the Hudson Bay and the intertwined environmental experience. Unlike other areas of Northern Canada, areas in Northern Quebec, Manitoba, and Ontario are subject to multiple political systems (i.e. provincial, federal,

and the " Arctic Archipelago" and the highest apical peak of Nunavut is “Barbeau Peak".

Arctic Lowlands is one of the geographic regions in Canada. This geographic region covers part of Nunavut. This region has flat, low area. It is also composed of series of low islands located in the far north of Canada, Nunavut. The climate is the Arctic Lowlands is very harsh. The climate is so bad that the ground remains frozen almost all year. Another thing this region is known for is large scale exploration for minerals such as gold and diamonds. This region is also the home of the largest supply of fossil fuels. This region also contains large amounts of lignite (a form of coal),l oil, and natural gas deposits.

The Arctic Lowlands are found between the Canadian Shield and Innuation regions. It is rocky with rounded hills. Also the surface is frozen all year. There is atleast a day in a year that the whole day is darkness. some of the natural resources you can find is coal,lead,ainc,soapstone, and natural

“Following Tertiary time during the Quaternary Period (the most recent 2 to 3 million years) the major sculpturing of Pacific Coastal Alaska began” (Anthony and Tunley 1976). Layers of snow deposited on the high mountains from moisture-laden winds of the Pacific. Over time, the snow compacted into ice; growing into large ice fields, moving, grinding, and carving out the landscape in a flowing movement to the sea. Glaciers advanced and retreated four times during the Quaternary Period (Anthony and Tunley 1976). Nunataks or isolated peaks projecting through ice or snow remained visible during maximum glaciation. “Maximum glaciation provided ice the ability to cap the Pacific Coastal Ranges and extend to the Gulf of Alaska or all the way to the
