Ninnis Glacier Essays

The men and crew of the Endurance were a strange picking out of hundreds, if you ask me. A motley crew of twenty-seven men, a wide mix of artisans, scientists, and seamen. Their leader, Sir Ernest Shackleton, was the only man keeping them from death. It isn’t flattery when people say that without The Boss, it is very possible that not all of the men would have made it back to England alive. The lack of casualties is astounding. The Irishman was an explorer at heart, a man whose soul seemed to be

When we hear the word “glaciers melting”, many questions and thoughts such as “Why do glaciers melt? What is the cause of it? What are the effects of it? Why is it important for us to know and understand?” and so on would definitely come in to our mind. Yes, it is extremely significant for every one of us to know and understand because we are human and we are those who make it to happen. To be clearer, humans are the major cause of glaciers melting because human activities such as deforestation and

Alpine Biome: Information Report By Kent McMahon 1. Introduction This Information Report will contain detailed information about the Alpine Biome of the European Alps. The Alps are one of the mountainous and coldest biomes in Europe. Despite these harsh conditions, the Alps support a rich biodiversity of 30,000 fauna and flora. Furthermore, detailed information about a specific fauna and flora species that have unique adaptations to survive in the Alpine climate

Any piece of artifact has a meaning, a story, and a message. Artifacts can be interpreted and perceived in unique ways by different individuals. With many different personalized translations of an artifact, contremps are likely to happen. In the film Ice Age 2: The Meltdown, the story warns children about the impending horrors of climate change and extinction. However, others could say that the film brings the controversy that climate change is not caused by humans. Climate change is a long-term

Wegener was aware that a continental ice sheet covered parts of South America, southern Africa, India, and southern Australia about 300 million years ago. Glacial striations on rocks show that glaciers moved from Africa toward the Atlantic Ocean and from the Atlantic Ocean onto South America. Such glaciation is most likely if the Atlantic Ocean were missing and the continents joined. If the continents were cold enough so that ice covered the southern continents, why is no evidence found for ice in

The Wisconsin Glaciation Of Minnesota Many many years ago glaciers covered the northern half of the United States with ice. 75% of Minnesota was engulfed with thick moving ice, commonly known as the Des Moines Lobe. The Des Moines Lobe caused the Wisconsin Glaciation of Minnesota and shaped it into the wonderful state we know today. The Wisconsin Glaciation Of Minnesota constructing and destructing the landscape in Minnesota forever. Minnesota once had a glaciation period in the last

The Arctic Ocean is defined as the waters surrounding the North Pole, located within the Arctic Circle, including the northernmost islands of Canada, Norway, and Russia and is mostly covered by ice sheets, ice floes, icebergs and sea ice. Sea Ice is a thin, fragile layer of frozen ocean water that forms in the Arctic and Antarctic oceans. On average sea ice covers 20-25 km² of the Earth, accounting for 7% of the sea surface. The maximum extent of Sea Ice in the Arctic is recorded as 13-15x 10⁶km²

observe global warming and the effects it was having on the immediate environment. The effects of climate change are being felt in every corner of the globe, especially in the Arctic. Currently, because of climate change, the permafrost is melting, glaciers disappearing and sea ice receding. Attwood even talks about the disappearance of the permafrost, “The northern permafrost melted and the vast tundra bubbled with methane.” This comparison to our world can not be ignored, the rapid disappearance or

In Newtok Alaska, the villages are built on frozen solid soil. With the climate changing the soil is thawing out and the ice is melting. Some villages have even begun to sink in into the ground. Now the villagers must relocate to higher ground and must rebuild on solid ground that won't be affected by the climate change. Humans are the main cause of global warming, but at the same time we are the only ones who can stop it. For centuries, atmospheric carbon dioxide has never been higher than it is

The geologic time scale subdivides the 4.6 billion years of the earth history into a hierarchy of time periods corresponding to the history of the earth formation (Canada 2010). The Precambrian era began with the formation of the Earth and followed by the Paleozoic, Mesozoic, and Cenozoic eras. Each of these eras is divided into periods, the periods into epochs, and epochs into ages (Canada 2010). Geologically, Canada is one of the oldest countries in the world, and Precambrian rocks extend over

Resisting this are a number of components that are thought to interact with each other: the friction between the avalanche and the surface beneath; friction between the air and snow within the fluid; fluid-dynamic drag at the leading edge of the avalanche; shear resistance between the avalanche and the air through which it is passing, and shear resistance between the fragments within the avalanche itself. An avalanche will continue to accelerate until the resistance exceeds the forward force. Modeling

breathtaking bluffs and the large body of water there is today. One popular theory scientist have about Devils Lake is that years ago the Wisconsin River flowed through the gorge but the water became trapped between the glaciers. Over time the water trapped between the two glaciers became the well known lake. The lake became useful to many people throughout the ages. According to OnMilwaukee, evidence has come to the conclusion that 10,000 years ago prehistoric people used Devils Lake as shelter.

According to the Alaska Dispatch News article. Glaciers are melting drastically and loosing 75 billion tons of ice a year. If all the glaciers melt in Alaska then a foot of water will be on top of the land from the melted glaciers. From the recent climate changes of the weather getting warmer, the glaciers are melting faster. Sea level is also rising from the melting of glaciers. Anchorage is under sea level therefore Anchorage may become a lake. Also the Cook Inlet sound is along Anchorage and current

Studying the cores of ice can help us decode the climate of the past. Here’s how. First, let’s define ice core. An ice core is a cylindrical sample of ice drilled from a glacier. These provide the most direct and detailed way to identify past climates. Every year, it captures sediments such as dust and sea salts. It can even collect human pollutants. If we know what each layer of ice counts for in years, we can figure out the average temperature per year and see any recent climate events, such

The last Ice Age is dated to have occurred about 1.8 million years ago and it is stated that it approximately lasted for 11,700 years; concluding the last Ice Age our planet has seen a huge shift in the glaciers that once had covered large parts of earth. Over the last 800,000 years, in a period that is called the Pleistocene, we see a long-standing pattern in ice sheet growth and decline across glacial (cold) and interglacial (warmer) periods.1 Global warming should no longer be a topic of debate

Snow Blowers and Throwers are machines for removing snow from unwanted areas like roadway, runway, sidewalk, railroad track or driveway. Both snow thrower and snow blower are slightly different from each other, snow thrower uses a single stage to remove the snow and snow blower uses two stages to remove snow. These machines either use electric power, diesel or gasoline as fuel source to throw snow to another location. Snow throwers ranges from the very small size, capable of removing only few inches

ice age occurred during the Pleistocene epoch, with huge parts of the Earth’s landmasses being covered by glaciers. The Pleistocene did not consist of just one great ice age. Instead, it involved frequent fluctuations of warming and cooling of the Earth’s atmosphere. This included more than 30 changes between long glacial periods where much of the world’s temperate zones were covered by glaciers and brief warmer interglacial phases where some ice sheets retreated; much like what we are living in today

In her article, Bethel compared our culture to an iceberg. This simile (comparison) was noted several times. She says “Imagine culture as an iceberg,” “But like an iceberg, most of culture exists below the surface,” and “Like an iceberg, culture exists below the surface” (Bethel, paragraph 6). For all those that has watched The Titanic, you should have remember that this huge cruise ship was sunken by an iceberg. Thus, one who has looked closely at an iceberg, would know that only about 10% of an

Characteristics of an Alpine Biome: The Alpine biome is summed up as ice, snow, high winds, basic things that come with winter. Alpine biomes can be found all over the world in a variety of mountain regions. Usually they are at an altitude of 10,000 feet or more, and lies just below an snowline of a mountain. In the Rocky Mountains of North America you would first begin in a desert biome, Then as you proceed to climb through a brief forest biome, steppe biome, taiga biome, and grassland biome

6) Explain the formation of a pingo including a couple of photos.* Pingos are dome-shaped, isolated hills which interrupt the flat tundra plains. They have diameters of around 500 m and may be as much as 50 m in height. These occur in sand and therefore are not susceptible to frost-heaving. In open-system pingos, surface water infiltrates into upper layers of ground where it circulates in the sediments before freezing. This water freezes, expands and forms localized masses of ice and the ice forces
