Throughout history and even today‚ men and women are attracted to the activity of exploring Antarctica‚ despite this continent having one of the harshest environments in the world. Severe winds and temperatures of down to -41 degrees Celsius have been reported on recent expeditions (Shackleton Solo‚ 2015). In 2015‚ Henry Worsley commenced a Trans-Antarctic expedition to commemorate the life of Sir Earnest Shackleton and aimed to follow in Shackleton’s planned expedition route which the Endurance

LAKE A lake is a body of relatively still water of considerable size‚ localized in a basin‚ that is surrounded by land apart from a river‚ stream‚ or other form of moving water that serves to feed or drain the lake. Lakes are inland and not part of the ocean and therefore are distinct from lagoons‚ and are larger and deeper thanponds.[1][2] Lakes can be contrasted with rivers or streams‚ which are usually flowing. However most lakes are fed and drained by rivers and streams.Natural lakes are generally

by landmasses‚ and others take detours around islands. Only the Antarctic Circumpolar current flows all the way around the Earth uninterrupted. For at least 25 million years‚ the Antarctic Circumpolar current has helped insulate the waters around Antarctica from other oceans. The current helps keep warmer waters away from the continent. Ocean currents help transport heat and cold‚ playing a key role in the Earth’s climate. There is therefore a need for data‚ so that the scientist may keep track of

that was found‚ is today being held in the British Museum of Natural History. It was reportedly found by an anonymous Maori in New Zealand in 1859 and was named Palaeeudyptes Antarcticus despite the fact that the species was located far away from Antarctica. Since that discovery many more fossils were found and were dated back to the Miocene era and three others from the Pliocene era. Several fossils were dated to the Late Pliocene era and others from the Recent era. The earliest avian fossil found

During the winter for many years penguins had to face some of the harshest climate changes in Antarctica; This alone will be the cause of functional adaptation and the start of evolutionary changes. These changes added to the challenges which they endured each winter for survival. These penguins would walk miles to get to the nesting grounds a place where it was safe for them to mate and live with their nuclear family. The nesting grounds was miles away from the shore end so penguins would have to

A habitat is an ecological or environmental area that is inhabited by a particular species of animal‚ plant‚ or other type of organism.[1][2] It is the natural environment in which an organism lives‚ or the physical environment that surrounds a speciespopulation.[3] A habitat is made up of physical factors such as soil‚ moisture‚ range of temperature‚ and availability of light as well as biotic factors such as the availability of food and the presence of predators. A habitat is not necessarily a

Global climate change is upon us‚ and the visible effects are ubiquitous. One of the most temperature-sensitive organisms on earth‚ coral‚ is proving to be the litmus test in this contentious issue: bleaching (a process by which coral reefs lose their life-giving algae) has become more widespread in the past decades as sea temperatures rise‚ causing reefs to “’collapse catastrophically’” (Markey). Colder regions‚ too‚ are feeling the heat. In the Arctic‚ shrinking sea ice is disappearing at a rate

* 2. The opening scene shows the collapse of a massive ice shelf (a floating glacier) in Antarctica. Could this really happen? If so‚ how might this affect global sea levels? Happens all the time‚ always has. Only affects sea level if the rate of ice shelf collapse increases or decreases significantly over a long period of time. 3. Is it realistic to think our climate is in a fragile state? What does burning fossil fuels have to do with global warming ice caps? Oil and gas are hydrocarbons

The Antarctic Circumpolar Current (ACC -- also the "West Wind Drift")‚ flows in the Southern Ocean around Antarctica‚ and nothing gets in its way. It’s the strongest current on Earth. People may be expecting else to take you "around the world" but that is the correct answer. Always flowing from west to east. 4. If you were traveling from South America to Labrador
