Antarctica sea levels rising faster because of fresh water from melting glaciers, say researchers

“Fresh water is less dense than salt water, and so in regions where an excess of fresh water has accumulated we expect a localized rise in sea level”

Sea levels around Antarctica are rising faster than anywhere else in the southern ocean. The global average rise in ocean heights in the last 19 years has been 6cms, but the rise in seas around Antarctica is 2cms higher.

Antarctica ice sheet melting episodes have occurred over the last 14.000 years, say scientists

The melting of the Antarctic Ice Sheet wasn't thought to have started, however, until 14,000 years ago.

A new study has found that the Antarctic Ice Sheet began melting about 5,000 years earlier than previously thought coming out of the last ice age, and that shrinkage of the vast ice sheet accelerated during eight distinct episodes, causing rapid sea level rise.

Antarctica ice sheet loss has doubled since 2010, shows CryoSat satellite

Altogether, Antarctic ice loss is now contributing 0.45 millimeters to global sea level rise each year

The Antarctic ice sheet has lost ice twice as quickly in the past three years as when it was last surveyed between 2005 and 2010, say scientists. Results from the CryoSat-2 satellite mission, published Monday in the journal Geophysical Research Letters, say the largest ice sheet on Earth is now losing 159 billion tons of ice each year.

Live avian influenza virus discovered in Antarctica Adélie penguins

“We found that this virus was unlike anything else detected in the world,” said Hurt ( Pic Aeron Hurt, WHO)

Researchers have found a new type of avian influenza virus in a group of Adélie penguins (pygoscelies adeliae) from Antarctica. Aeron Hurt, PhD, a senior research scientist at the WHO Collaborating Centre for Reference and Research on Influenza in Melbourne, Australia, said that this is the first time that a distinct, live flu virus has been found in these birds.

Russian vessel incident triggers debate on Antarctica growing tourist industry

French Polar Institute director Yves Frenot was furious with incident that distracted several icebreakers from their normal duties

The challenging rescue operation launched after a Russian ship became trapped in Antarctic pack ice in December shows the inherent risks facing the frozen continent's burgeoning tourist industry, experts say. Antarctica represents one of the last frontiers for adventurous travelers, an icy wonderland of glaciers, emperor penguins and seemingly endless white expanses.

Three icebreakers to the rescue of Antarctica trapped Russia's 'Akademic Shokalskiy'

The Russian vessel trapped by ice every summer travels to Antarctica

Seventy four people spent Christmas aboard a cruise ship that has become stuck in the ice in a remote region off the coast of Antarctica and rescue vessels are at least two days away, according to Australian maritime officials. Three icebreakers are sailing to the rescue.

Ozone layer hole reaches Argentine and Chilean Patagonia

In Rio Gallegos the UV intensity index has jumped from four to ten, according to Spain's Atmospheric research

The hole in the ozone layer over Antarctica stretched for the third time this year to reach cities in the south of Argentina and Chile according to the Izaña Atmospheric research centre in Tenerife, Canary Islands.

Channels nearly as tall as the Eiffel Tower gouge into the undersides of floating ice in western Antarctica. The recently discovered channels could influence how quickly Antarctic ice sheets slip into the sea, melt, and contribute to rising sea levels.
