Latest Ice shelves of Antarctica Stories
British Antarctic Survey has captured dramatic satellite and video images of an Antarctic ice shelf that looks set to be the latest to break out from the Antarctic Peninsula. A large part of the Wilkins Ice Shelf on the Antarctic Peninsula is now supported only by a thin strip of ice hanging between two islands. It is another identifiable impact of climate change on the Antarctic environment.
Under the former Larsen ice shelf east of the Antarctic Peninsula, deep-sea sea cucumbers and stalked feather stars were ubiquitously found in shallow waters. These animals usually inhabit far greater water depths.
Scientists in Antarctica spent Christmas Day finishing work that may show the effects of global warming - drilling for clues about how massive ice sheets responded to past temperature changes. The project will be vital to creating a map of how the Earth may react to higher temperatures, scientists say.
The spectacular disintegration of Antarcticaâ€™s â€œLarsen-Bâ€ Ice Shelf was unprecedented since the last ice age, according to a recent study to be published next week in Nature. And the disintegrating Antarctic ice could have huge implications for global warming and rising sea levels.
An expansive ecosystem of knee-high mud volcanoes, snowy microbial mats and flourishing clam communities lies beneath the collapsed Larsen Ice Shelf in Antarctica, say researchers.
By Jeremy Lovell LONDON (Reuters) - Designed to cope with one of the most inhospitable environments on Earth, the winner announced on Tuesday of an international competition to build a new ice station in Antarctica resembles a giant blue centipede.
The chance discovery of a vast ecosystem beneath the collapsed Larsen Ice Shelf will allow scientists to explore the uncharted life below Antarctica's floating ice shelves and further probe the origins of life in extreme environments. Researchers discovered the sunless habitat after a recent underwater video study examining a deep glacial trough in the northwestern Weddell Sea following the sudden Larsen B shelf collapse in 2002.
Findings show that ice fracturing occurs in episodes and may be tied to changes evolving over seasons.
The current retreat of ice shelves in the Antarctic due to global warming is nothing new - but this time the problem is manmade and therefore potentially more serious, according to research released Wednesday. A recent survey has shown that ice shelves retreated thousands of years ago as a result of rising air and ocean temperatures.
