Antarctica

Notwithstanding the relative extents of ice that have been lost in the northern and southern halves of the globe, we can likewise observe there's been an authoritative increasing speed of ice misfortune in most recent 20 years. So together Antarctica and Greenland are presently contributing three fold the amount of ice to ocean levels as they were 20 years prior," says the Professor of Earth Observation. As indicated by the examination, dissolving ice from the two shafts has been in charge

(0 degrees celsius) what happens to life beneath the ocean when temperatures plummet in Antarctica? There has been recent discoveries of antifreeze proteins in Antarctic fish. Dr. Arthur DeVries was the first to discover such proteins, in the 1960s, and describe how they bind in the blood of fish to ice crystals and prevent the fish from being frozen. DeVries and his colleagues originally went to Antarctica to study respiratory metabolism in fish but what he noticed was that when they caught the

This video was about Ernest Shackleton expedition to Antarctica in 1914. This expedition was supposed to be first to cross continent with their Trans continent boat Endurance. Shackleton chose 27 men to serve a variety of positions, such as running and navigating the ship, cooks, scientists, surgeons and photographer. His expedition failed to cross the continent, because his boat got trapped in thick pack ice, and man were forced to abandon ship and continue expedition on foot and smaller boat to

Antarctica is the fifth largest Continent on the world map which covers close to 14.2 million square kilometres of land space that includes the ice sheets which unfolds onto the sea (Martin, 2013). Antarctica once used to be part of Gondwana supercontinent until it fragmented itself 70 million years ago and moved to the South Pole making it isolated from other land areas (Martin, 2013). Antarctica was once ice free, had temperatures well above freezing point and was also filled with greeneries forty

Antarctica is an unrivalled continent and well known for the extreme environmental conditions, as the temperature is lowest, high wind speeds, high UV-B radiations and isolated landmass on earth. Growth conditions for the organisms are extreme and plants exists with the physiological limits of survival over Antarctica. Antarctica having terrestrial biota comprising microorganisms, ichens, fungi, algae, bryophytes and invertebrates. Cryptogams are the major components of the Antarctic flora and their

paper will focus on three regions of the Earth in particular: Antarctica, the Amazon Rainforest, and the Great Barrier Reef. More specifically, it will examine the extent of the impact that global warming has had on each region.. 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

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

What makes Antarctica unique regarding human geography, is how humans influenced the continent. physical geography is far more significant than human appearance. Antarctica is a cold, frozen, and mostly empty land found at the South Pole of the earth. Antarctica is a cold, frozen, and mostly empty land found at the South Pole of the earth. Humans go there mostly for research and occasional tourism, though it's incredibly inhospitable, especially in the colder months. Due to the harsh environment

Cox completed an unthinkable challenge. The challenge itself was only 1.06 miles and lasted twenty-five minutes, which doesn’t seem like a long time but for her it lasted a decade. Cox wrote an autobiography about her journey titled Swimming to Antarctica. Within Cox’s book she relives the phenomenon at which she faced the frigid unknown. That one day Cox would put everything she had into a dream only she could possibly achieve due to her physical and mental stability. Lynne Cox was an overall

Antarctica is land that is the least explored. It holds mysteries and is beautiful with all its unique landscapes. the authors of “The Last Wilderness Preserve” and “A New Land of Opportunity” both understand this, but both argue two different side on the topic of whether Antarctica should be kept isolated from humans and left alone or be explored and plundered of its resources. Both passages explain their sides of the argument and one passage is more efficiently supported than the other. In the
