The Effect Of Ocean Ices In Antarctica

Antarctica is one of the most rapid warming areas on the Earth, climate change on Antarctica is crucial to the world and the continent itself. Although climate change on Antarctica isn't widespread as it a wide place, only a small amount of impact is taking place. Some areas in Antarctica are experiencing decreases within the sea ice whereas other areas have an increase in sea ice. Both changes are causing negative impacts on wildlife. (Antarctic and Southern Ocean Coalition, 2014) Climate change has been a continuing scientific curiosity. Climate change is raising many concerns on not only the environmental and regulatory concerns but also within the economy, health, security, safety, and food production. (UNEP, 2009)

Antarctica is The world's fifth-largest continent,The landmass is made up of 98 percent ice and 2 percent rock holds the distinction of being the coldest, windiest, driest, and highest continent. Antarctica takes up about 5.4 million square mi. The icy plains highest point is Vinson Massif at 16,066 ft and lowest point is the Bentley Trench at −8,382 ft.

Economic growth is vital to sustain human life; however, the unsustainable consumption of natural resources to attain this demand is leading to self-destruction. The Earth is facing environmental changes, including climate changes, which are altering the Earth system. Significantly higher thermal expansion is inescapable if the increasing pollution by carbon dioxide emission continues relentlessly. One evidence of this change is global warming and its impact in the Arctic Ice. The critical role of the Arctic in the global climate system implies that Arctic Ice changes will have far-reaching connotations for, and feedbacks to, the entire Earth. Currently, the warning signs include: rapid diminishing of sea ice, increased mass

Nelly said “It’s getting hot in here (so hot)”, but because research shows how temperatures are not significantly increasing, people may want to keep their “coats”. “Global warming” occurs when greenhouse gases release into the atmosphere, causing the Earth's surface temperature to rise (Overview of Greenhouse Gases). Although some people think that greenhouse gases only cause harm, this is not true. Gases released into the atmosphere warm the Earth to a potentially harmful temperature, which supports the argument of “global warming”; however, these gases also cool the Earth, balancing the temperature (Overview of Greenhouse Gases). Without greenhouse gases, the Earth would be mostly frozen. Some scientists argue that Earth’s temperatures rise

Antarctica is essential for science because of its enormous effect on the Earth's climate and ocean systems. The Antarctic is critical our understanding of global climate change. Preserved in its four kilometre-thick ice sheet is a unique record of the

“The Glacier, and with it the Duck, might have moved since then.” Lou Sapienza is the lead organizer of a Coast Guard Operation searching for a missing World War II plane; the Grumman Duck and its lost crew. A challenging problem the party has with finding the Duck is the movement of glaciers since the planes went down close to 70 years ago. Since the 1950s the extent and the movement of the ice sheets have rapidly changed due to Global Warming. Most affected by this climate change is The Arctic, Antarctica and the Greenland Ice Cap. Lou Sapienza and his team of specialists only have a hand-drawn map of where the Duck crashed and an old radar survey from years ago. Their daring task is to predict how the movement of the ice sheet accelerated by global warming might have moved their missing plane. Since global warming is a problem, everyone will be affected by it in one way or another. It is time to act, to confront the problem and find a solution.

The sun power and warm’s are earth, as two thirds of solar-energy enter our atmosphere as visible-light, the greenhouse effect absorbs the solar-energy to keeping the earth warm and later releases one third back into outer space. Without the “natural greenhouse effect” the earth's temperature would be below 32 degrees fahrenheit (The freezing point of water). The burning of fossil fuels as an energy source releases a variety of gasses such as Methane, nitrous oxide, and CO2 adding to the greenhouse effect. Because of this heat is kept longer, warming our atmosphere and causing what we know as global warming. One of the issues with global warming, is the destruction of ice polar caps that contributes to the rise of the ocean level, and causes

In order to provide context for the recent decline of ice in the sea, it is imperative to understand how the sea ice has varied over the past two centuries. Of particular interest, the period around 1920-1940 showed an “increase in almost twice the global average rate in past 100 years. [ ]” The warming during this time can be used to compare the decline of sea ice observed since 1979, but what will also be discussed is how this time period was also quite controversial due to its substantial variance between the official views and views held by other people. The reliability of the sea ice observations during the first half of the 20th century according to some people cannot provide certainty to estimating

Sea ice has significant importance in the northern Arctic. The sea ice is extremely vital for the marine animals that live in this ecosystem. In particular the sea ice allows them to hunt, mate, and travel. The sea ice allows animals such as polar bears to hunt and search for their prey that lives underwater. It helps females and males find mates to grow their population, and lastly the sea ice allows for polar bears to travel from different locations. Another reason for the importance of sea ice is that it helps keep our planet cool particularly through the albedo effect (Kaitlin, 2016). Potential consequences of the melting of the sea ice could have devastating effects of marine animals in the north, and also for our entire planet because

Millions of miles of ice and an unfriendly environment make Antarctica an exciting place to study. It is very unique, and doesn’t have the same properties as the other continents do. It is much colder than the rest of the world. For example, the average temperature in Antarctica during the summer months is about 32 degrees fahrenheit! The coldest temperature ever recorded anywhere was in Antarctica, at the Russian Vostok station. It was -129.3 degrees fahrenheit!! In addition, the continent contains 90% of the world’s ice, and it is bigger than the United States. “It is the coldest, windiest, and driest continent in the world”. (Redd) In fact, the average precipitation there is only 2 inches every year. Believe it or not, Antarctica is classified as a desert, because it is so dry, and has such a minimal amount of moisture. “More rain falls in the Sahara Desert”. (Redd) Even though there is very little snow, Antarctica still has massive blizzards. The heavy winds pick up snow from the ground and blow it around. Winds in Antarctica have been known to reach 200 miles

0% since the 1970s. Less sea ice during the winter is likely to be the cause and may explain declines seen in several species of penguins. Krill feed on the algae found under the surface of the sea ice, which acts as a kind of ‘nursery’. The Antarctic Peninsula, a key breeding ground for the krill, has experienced a striking decrease in sea ice.

Since many of have already discussed rift valley characteristics, I’ll talk about the lesser known West Antarctic Rift. This rift valley lies between East and West Antarctica. It is difficult to study the West Antarctic Rift because it lies beneath the over 2 kilometers thick Antarctic Ice Sheet. This rift developed due to lithospheric thinning of the non-cratonic area of West Antarctica. The West Antarctic Rift is the source of all the recently active volcanoes within Antarctica and most of the major Antarctic mountain systems outside the Antarctic Peninsula. The rift influences ice flows in West Antarctica due to fast moving ice streams influenced by the lubrication from water-saturated till.

In antarctica it’s the coldest and windiest continent on Earth making it extremely easy to get frostbite a horrible and painful condition. Frostnip is the first step of frostbite where the tissues begin to cool without any cellular destruction. The area affected may change color usually a pasty white. Once the wind chill makes the temperature feel like -24 or colder, skin exposed can freeze in less than 30 minutes. To avoid frostbite don’t have any skin exposed or wet clothing on, it will just make the tissues in your body freeze faster . The expedition Shackleton and his crew took on when their ship sank they were outside,under a boat or in a tent . They didn’t have enough blankets or dry clothing for everyone making the risk of frostbite

Climate change is a problem in the world today. Climate change is destroying Antarctica, endangering hundreds of millions of lives, and can be effectively reduced by reducing greenhouse gas emissions.

Antarctica is one of the coldest and darkest environments on Earth. Below these Antarctic ice sheets lay some of the largest subglacial lakes and it is within these lakes that scientists believe contain some of the most unique microbial ecosystems on earth. Antarctica’s subglacial lakes are some of the most oligotrophic, or nutrient deficient places on the planet (Karl et al, (1999). It is this scarce landscape that inherently affects the organisms that are present. Significant research has been undertaken by scientists to better understand the physical processes of how these subglacial lakes are created, and how this then affects the hydrology of these lakes. The amount and type of life that is said to live in these lakes is determined by the hydrology that occurs as a result of the various physical processes. Both biodiversity and biomass with respect to the types and amounts of organisms present is restricted due to the amount of ice depth and the lack of nutrients for these organisms like archaea, bacteria and viruses.
