The subject of my paper is Harp Seals. I choose this topic because I find it interesting how their senses help them survive the harsh environment. I also chose it because I love Harp Seals‚ they are the cutest and fluffiest Arctic animals. Harp Seals‚ also called Pagophilus groenlandicus (in means "ice-loving seal of Greenland)‚ is one of the nineteen species of marine mammals in the family of True Seals. (Hogan‚ 2010) They form the group of marine mammals known as pinnipeds. Their ancestors were

For a long time researchers have been trying to retrieve data on Grizzly bear diets. It is clear that all Grizzly bears have different habitats‚ food sources‚ and outside pressures such as human development. Although this is true Grizzly bears have been seen to commonly have the same diets over the course of seasonal shifts. For example‚ Grizzly bear diet and use of seasonally abundant‚ nutrient-rich food sources has been well documented throughout their range in North America. A wide diversity of

09/30/2012 Jocelyn Henson Climate Change Effects on Artic Polar Bears Climate warming and ecological changes have caused a significant threat to the declining population of polar bears in the Arctic which is affecting human habitats Polar bears‚ the largest of the terrestrial carnivores‚ live on the Arctic ice for the majority of the year. The icy habitat allows polar bears to hunt for their primary prey - seals. The powerful species’s survival completely depends on their ability to use ice for

Hudson‚ his son John and eleven other crew members sailed from England on the Hopewell ship. They went past the Greenland and towards the North Pole. Hudson and his crew hoped if they would find an easier way to get from England to the Far East of the Arctic Ocean. They kept on trying but unfortunately Hudson and his crew couldn’t find the Northeast Passage. The Muscovy Company didn’t send him to anymore explorations. In 1607 Hudson moved to Holland and sailed for a Dutch East India Company on the ship

According to Arctic Melt Unnerves the Experts article “The Arctic ice cap shrank so much this summer that waves briefly lapped along two long-imagined Arctic shipping routes‚ the Northwest Passage over Canada and the Northern Sea Route over Russia” (NY Times‚ 2007). Ice glaciers are melting and sea levels are increasing. The climate change

Since 1920‚ primarily due to the climate change‚ glaciers and ice caps across the Arctic have shown shrunk lessens in volume and glacier fronts‚ leading to the rise of sea lever (Prowse et. al‚ 2009a‚ p.277). Moreover‚ the annual averaged area of sea ice in Northern Canada has decreased by 7.4% from 1978 to 2003 (Prowse et. al‚ 2009a

The beluga whale (Delphinapterus leucas) is a cetacean inhabiting the marine arctic and is found throughout the arctic seas as well as smaller seas such as the Beaufort Sea‚ the Chukchi Sea‚ the Bering Sea‚ Cook Inlet‚ and several other seas (Frost and Suydam‚ 2010). This species is migratory and will migrate to shallower coastal waters during the summer‚ but as winter approaches they travel back to the northern icy waters (Goetz et al.‚ 2012). Beluga’s feed on small fish‚ as well as squid‚ octopus

Melting Ice Caps The Arctic is global warming’s canary in the coal mine. It is a highly sensitive area which is profoundly affected by the changing climate. The average temperature in the Arctic is rising twice as fast as elsewhere in the world (nrdc.org). Because of this‚ the ice cap is getting thinner‚ melting away‚ and rupturing. Here is an example of this; the largest ice block in the Arctic‚ the Ward Hunt Ice Shelf‚ had been around for 3000 years before it started cracking in 2000 (nrdc

Oxygen – Carbon dioxide Cycle The Carbon Dioxide- Oxygen Cycle relates to the relationship between Carbon Dioxide [CO2] breathing plants and Oxygen [O2] breathing life forms. All oxygen-breathing life forms take in Oxygen and exhale CO2. Plants take in the CO2 and use it in their photosynthesis process and in turn give off oxygen. The Carbon Dioxide-Oxygen Cycle is a continuously occurring process whereby animals inhale Oxygen and then exhale carbon dioxide‚ and plants use the CO2 and "exhale"

Ryan Jang Reading November 25‚ 2012 Open-Ended & analysis Arctic Meltdown 1) I think that scientists are careful when measuring the Arctic sea ice at the same time every single year is if they don’t record the data at the same exact date every year‚ let’s say they make a graph with annual measurements at the same day every year all the records since the 80’s to now well then the graph would be wrong. The scientists have to be consistent to
