Arctic Ocean

They have white-yellow fur that help them camouflage into the snow and ice in order to help them catch their prey. Polar bears live in the Arctic region. They live on the ice, the coast and islands of the Arctic region. I think climate change and overhunting are most likely to influence the future of the polar bears. I believe climate change is a factor because it causes the loss of ice habitat for the polar bears. This is…

Another vertebrate that lives in the tundra is the polar bear. Polar bears can be found in northern areas of Canada, Alaska, Russia, and Norway. They are also located in various parts of Greenland. Polar bears are among the largest land mammals on earth. Males can weigh between 700-1400 pounds and stand between 8-10 feet tall. Females only weigh about 350-700 pounds. Polar bears appear to have a white coat, however, their hairs are really translucent and clear. The skin of the polar bear is…

Exceptional monitoring efforts have established a shift from Arctic to Subarctic climate regime within the last decade (Grebmeier et al. 2006). Building on the existing 30-year record of direct observations on the water column and benthic macrofauna, I will extend this record back to the last glacial maximum using…

taking place in the Arctic, especially the physical changes resulting in challenges to Canada’s sovereignty. Sovereignty means the authority of a state to govern itself or another state. In today’s society, claiming sovereignty has become has become a major factor in causing international conflicts and disputes. To ensure security in this day and age, Canada’s government must continue pursue its jurisdiction over the Arctic, due to increased interest in the area. The attention the Arctic…

Appearance, diet, habitat, natural (or introduced) predators, and reproductive habits Polar Bears live in an arctic marine ecosystem, and its native range lies largely within the Arctic Circle, encompassing the Arctic Ocean, its surrounding seas and surrounding land masses. Polar bears have a distinctive white appearance. Their necks are much longer and their head is narrower compared to other species of bears. The front paws are large and used like paddles for swimming. Paws are heavily furred…

The Beaufort Gyre, a major anticyclonic circulation feature in the Arctic Ocean, hosts a substantial fraction of the overall Arctic freshening citep{haine2015arctic}. The large-scale gyre circulation has been directly linked to its freshwater content (FWC) via the process of Ekman pumping that converges relatively fresh surface waters and deepens the halocline citep[e.g.][]{proshutinsky2002role}. The Ekman pumping arises due to transient anticyclonic winds that cause significant gyre…

Ender’s Game has several gripping characters that largely contribute to the story. The three Wiggin siblings are like the three bears from Goldilocks and The Three Bears. Peter is like the father bear; his personality is too hard, just like the father bear’s bed. Valentine is like the mother bear; her personality is too soft, just like the mother bear’s bed. Then there was Ender. He is like the baby bear; having everything be just right. However, you couldn’t have a respectable story without any…

growing concern on the conditions of the Arctic when factoring Global Warming. Most scientists believe the last 50 years of constant temperature changes in the world is due to human activity and the burning of fossil fuels. Many also take in the natural factors, for example, variations in the solar radiation, where major volcanic interactions and eruptions between the ocean and the atmosphere. Many people on earth do not understand the importance of the Arctic and what major roles it plays in…

slowly, but they do this to keep a stable body temperature. Polar bears release extra body heat through their muzzle, ears, and footpads. These adaptations are examples of homeostasis. The only place in the world that Polar bears live is in the Arctic. Their habitats are divided into 19 subpopulations. Polar bears live along the edges of pack ice because water currents and wind work together…

for his chance to catch a walrus or any other food they can find. He tries to jump out of the way of the newly found hole in the ice, but slips. He swerves with all his might to get out of the way of the hole, and barely made it. Now, the ice in the Arctic is melting very fast, due to all the pollution we are causing, and the Inuit are living there, and have to watch as their home begins to melt. In other places, the Iroquois and the Sioux also have to watch the major changes that are being made…
