Change In Antarctica

Antarctica is the coldest, driest, and most inhospitable continent on Earth. Yet it is yields some 90 percent of the Earth most precious natural resource: water. But behind this pristine exterior, Antarctica is fighting a losing battle. New data suggests that the continent as a whole is warming at an alarming rate. According to recent studies gathered from Nature Magazine, the western half of the continent is warming five times faster than any other place

Collaborating on an international level remains important for conducting ice patch research due to the rapid melting of alpine ice and decay of valuable artifacts. The work conducted for this thesis included cooperation from Parks Canada. Ice patch research was conducted not only on the U.S. side of the international border, but also on the Canadian side of Chilkoot Pass. Parks Canada allowed me and KLGO archaeologists to use the Canadian warden cabin at the summit of Chilkoot Pass as a basecamp for the ice patch study (Figure 1.4). Working between two sovereign countries emphasizes the matter of climate change as a global issue and the importance in maintaining international relations. Maintaining international relations benefits the scientific community on a global scale and provides significant research opportunities.

A study that was created by Florida Institute of Technology, talked about how the king crabs who could hurt the ecosystem because of the warming waters. From the Antarctic Peninsula warming up is letting the king crabs go from their deep sea homes to the shallow waters. The land creatures will not know what to do if the crabs came up to the surface. With the other creatures, they never had seen crustaceans because they have been in the deep sea. With the data that was collected, it could not be proven that the crustaceans will move to surface. Researchers also found nothing that could stop the king crabs from coming up to the shallow waters even if it got warm. To prove the hypothesis, the hypothesis had to be tested. The researchers who worked

The article says that the ice sheets respond very slowly to changes in climate that it would take longer than a century for any large scale melting to begin. The ten scientists that have been studying the Earth’s history are not to alarmed with the melting of Antarctica and nor are they surprised it is going to melt so fast.

Where do Antarctica animals live? Seal lovers have given Antarctica the seal of approval because six species of seals live in the waters and on the frozen continent. The fiercest are leopard seals, which eat seafood but sometimes prefer to eat penguins and other seals. The biggest seals are bull southern elephant seals, which can grow up to 20 feet long. When challnging other males, the bulls inflate their large noses to make their bellows louder and scarier. Elephant seals, going almost 5,000 feet deep and staying under for as long as two hours. Many whales make their summer home in the waters of the southern ocean. Blue whales are not only the largest of the baleen whales but also

Ice is one of the first indicators of global warming actually occuring and it is important for research to be done on these layers of before they disappear. The recession of glaciers and the fragmentation of ice caps has been a clear sign to many that rising temperatures are having an impact, even on our very lives.

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

My world problem is climate changes effect on Antarctica. The cause of this world wide issue is an excess of carbon dioxide in the atmosphere. Carbon dioxide enters our atmosphere through burning fossil fuels. Carbon Dioxide levels have risen just nineteen percent since 1987-337 parts per million then to just over 400 parts per million now (Atkin). Ozone depletion high above Antarctica is due to chlorofluorocarbons and other greenhouse gases (Atkin). High carbon dioxide levels in earth’s atmosphere

At the first step, we find that the water of ice in the glacier about 60 meters in in the Arctic Pole content more salt than the ice of the Antarctic Pole, which meant that the warm ocean circulation coming from the Atlantic are accelerating the melting of the glacial bottom. And it would make glacier collapsing faster than we are expecting. The impacts of melting ice extend well beyond polar bears (which are one step away from endangered on the Conservation Scale). Birds, seals, and whales also use the ice for hunting. Birds nest in the sea ice and use it for protection while raising their young in the potentially deadly environment of the Arctic. Also the global fishing industry are influenced, and threaten human life. In addition, in the

The ice sheets in Antarctica and Greenland are changing rapidly and are contributing significantly to sea level rise (Church et al., 2011). In Greenland, surface melt leading to runoff and enhanced ice discharge from outlet glaciers have contributed in equal amount to the mass loss of the ice sheet (van den Broeke et al., 2009). In Antarctica, ice dynamics has been the dominant contributor to the mass loss in recent decades, but surface mass balance signal exhibits inter-annual fluctuations large enough to significantly modulate the mass loss. In the mountain glaciers of Alaska, Canada, Patagonia and others, surface mass balance (SMB) processes dominate the total mass balance (Larsen et al., 2015).

The name “Antarctica” derives from the Greek word antarktikos literally meaning “opposite to Arctic (North)”. The name is fitting as Antarctica is the southernmost continent on Earth. Antarctica is only the fifth largest continent in the world and is approximately 98 percent covered in a sheet of ice. This ice sheet is the single largest mass of ice on Earth. It covers an area of almost 14 million square kilometres (km) and contains 30 million cubic km of ice. Although the ice sheet contains around 90 percent of the Earths fresh water Antarctica can be classified as a desert by the coursehero.com definition: “A Desert is defined as a region that has less than 254 mm (10 in) of annual rainfall or precipitation.”

Please note that you will have 4 minutes to recall the 
facts, and that you will be taking the test immediately.” 
The word Antarctica was shown in italics to make it clear 
that they were only to be asked to recall information about 
Antarctica. Participants in the delayed condition were given 
the same prompt except they were asked to predict their performance after a 30-min delay: “In thirty minutes you will be asked to recall as many facts about Antarctica as you can. What percentage of 
the facts about Antarctica do you think you will be able 
to recall? Please note that you will have 4 minutes to 
recall the facts, and that you will be taking the test in 30 
minutes.” 
Participants were instructed to answer the prompt by telling 
the experimenter a number between 0 and 100. 
Participants in the immediate condition were then given a 
blank sheet of paper and 4 minutes to recall as many facts 
about Antarctica as possible. Participants in the 30-min delay 
condition were given the same test after a 30-min interval, 
which was filled with a series of unrelated distractor tasks 
(e.g., learning and retrieving category-exemplar pairs). It is 
worth noting that participants were not informed of the nature 
of the distractor tasks before making their predictions, a factor 
which may have influenced the accuracy of such predictions. 
Given the purpose of the study, however, we felt it was more 
important to focus instructions on the particular passage that 
was to-be-tested

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.
