Arctic Ocean

Narwhals Hey fifth grade! I find narwhals very interesting, and for one thing narwhals are also known as “the unicorns of the ocean”; because of their horn-like tusks. They are “one of the rarest whales in the world”. Narwhals diets consist of squid, fish, and shrimp. They are normally “found in the Atlantic and Russian parts of the Arctic”. Narwhals don’t move very fast until they are being chased by a predator”. Narwhals travel in groups of 10-100, or sometimes more. Narwhals are…

For centuries the Arctic Ocean has been famed for its inaccessibility, but with unprecedented ice retreats in recent years as a result of global warming, the Arctic Ocean is becoming rapidly accessible. This means new possibilities for the Arctic countries in terms of trade, travel, and access resources. These recent changes in the topography have led many to portray the Arctic as a geopolitical race for natural resources and territory, with Russia seen as the main aggressor. Russia is depicted…

kingdom of narwhals is animalia. The phylum for dolphins is chordata the class of narwhal is mammalia. The geographic location for narwhal is in Greenland, Canada, Russia, and the Arctic Ocean. The biome where you can find narwhals is on the surface of the Arctic Ocean. Narwhals live in the icy waters of the the Arctic seas. In the winter, the narwhals go deep in water beneath the ice pack in groups of 5 to 10. In the summer, they migrate to shallow, ice free summer grounds where they gather…

Crossroads of the Arctic Council? When the Arctic Council was established in 1996 it was designed to bring together the states bordering the Arctic Ocean on issues related to environmental protection and sustainability. The organization does not address military issues in the region, which allows it to be one of the few international organizations in which both the U.S. and Russia will cooperate. However, I argue that there will be a change in the progression of this council in the next few…

The polar bear is an animal that you can find in the bitter Arctic region. The Arctic is located at the northernmost part of the Earth. The Arctic is basically covered in water and most is frozen. Some features that can be found in the water are icebergs and glaciers that are made of frozen freshwater. A fact about glaciers and icebergs is that they make up 20% of Earth’s supply of freshwater. Most of all the Arctic ocean is made of sea ice which is frozen seawater that often is covered with a…

There are two different types of tundra, they are the arctic tundra and the alpine tundra. The alpine tundra is located high in the mountains above the trees and the arctic tundra is in the article circle. In the tundra biome, there are many oil rigs and oil mines and they disrupt nature. The tundra biome is the coldest biome and covers about 20% of the earth. It is also the driest place on earth and only gets an average of ten inches of rain per year. In the summer time, it does not get dark,…

• Polar bears and brown bears can produce a hybrid offspring • Polar bears evolved from brown bears • The timing of when polar bears first appeared is vital because it determines when they have experienced warm periods with little sea ice historically • Mitochondrial DNA (mtDNA) – relationships based on differences in a group of genes • The polar bear genome discovered alterations in genes related to the development of the heart, cardiovascular function and lipid metabolism – this is why…

The Polar Regions are too cold to support a variety of life. However, scientists have discovered life forms that thrive in this cold environment, and they term the polar oceans as important in maintaining a balance on earth. The amount of water frozen in these regions can be destructive if melted nod released to the warm waters. The McMurdo station is a destination for many scientists to conduct their studies on the waters and the life forms that survive in the cold environment (Nold, 2002).…

Cross breeding plays an important part in the future of endangered animals. In the case of polar bears it may lead more quickly to the extinction of them. Within the past 10 years scientist have found several bears sharing DNA, in this case the two bears sharing the DNA are the polar bears and the grizzly bear. The earth has been heating up which means that the polar bears are getting pushed out of there land space, and are even starting to die off. The polar bears have to expand into the…
