Alaskan storm cracks giant iceberg to pieces in faraway Antarctica
A severe storm that occurred in the Gulf of Alaska in October 2005 generated an ocean swell that six days later broke apart a giant iceberg floating near the coast of Antarctica, more than 8,300 miles away.   view more (2006-10-03)

New Antarctic ice core to provide clearest climate record yet
After enduring months on the coldest, driest, and windiest continent on Earth, researchers today closed out the inaugural season on an unprecedented, multi-year effort to retrieve the most detailed record of greenhouse gases in Earth's atmosphere over the last 100,000 years.   view more (2008-01-24)

Geophysical Research Letters European Highlights - 1 August 2001
Highlights 4. Deep water has many sources Hellmer and Beckmann ["The Southern Ocean: A Ventilation Contributor with Multiple Sources"] use a coupled ocean/ice-shelf model to determine the location and rate of Antarctic Bottom Water (AABW) formation. Their results suggest that the Atlantic and... view more (2001-07-16)

Icy calculations on a hot topic
University of Utah mathematicians have arrived at a new understanding of how salt-saturated ocean water flows through sea ice - a discovery that promises to improve forecasts of how global warming will affect polar icepacks.   view more (2007-09-11)

Want to monitor climate change? P-p-p-pick up a penguin!
We are used to hearing about the effects of climate change in terms of unusual animal behaviour, such as altering patterns of fish and bird migration.   view more (2007-04-04)

Breakup of glaciers raising sea level concern
The rapid structural breakdown of some important parts of the ice sheets on Greenland and Antarctica is possible, has happened in the distant past, and some "startling changes" on the margin of these ice masses has been observed in recent years - raising disturbing concerns about sea... view more (2005-10-21)

NASA researchers find snowmelt in Antarctica creeping inland
On the world's coldest continent of Antarctica, the landscape is so vast and varied that only satellites can fully capture the extent of changes in the snow melting across its valleys, mountains, glaciers and ice shelves.   view more (2007-09-21)

Russia Returns To Arctic On A Drifting Ice-floe
After a long break Russia is getting ready to resume the research in Arctic with the help of floating stations. As Valery Martyshenko (Rosgidromet) has advised InformNauka, an appropriate ice-floe is currently being looked for, and the 32nd station will start the floating in the last decade of... view more (2003-03-25)

High degree of resistance to antibiotics in Arctic birds
In the latest issue of the journal Emerging Infectious Diseases, Swedish researchers report that birds captured in the hyperboreal tundra, in connection with the tundra expedition "Beringia 2005," were carriers of antibiotics-resistant bacteria.   view more (2008-01-14)

Ozone hole recovery may reshape southern hemisphere climate change
A full recovery of the stratospheric ozone hole could modify climate change in the Southern Hemisphere and even amplify Antarctic warming, according to scientists from the University of Colorado at Boulder, the National Oceanic and Atmospheric Administration and NASA.   view more (2008-04-25)

Geologists: Opening of passage may be tied to Antarctic cooling
Ancient fish teeth are yielding clues about when Antarctica became the icy continent it is today, highlighting how ocean currents affect climate change.   view more (2006-04-21)

Arctic ice on the verge of another all-time low
Following last summer's record minimum ice cover in the Arctic, current observations from ESA's Envisat satellite suggest that the extent of polar sea-ice may again shrink to a level very close to that of last year.   view more (2008-08-29)

Glaciers adding more to global sea rise than ice sheets, says University of Colorado study
Despite growing public alarm over the shrinking Greenland and Antarctic ice sheets, it is small glaciers and ice caps that have been contributing the most to rising sea levels in recent years, according to a new University of Colorado at Boulder study.   view more (2006-12-12)

Polar pecking order and biodiversity
New research into how biodiversity is generated and maintained in the seas surrounding hostile Polar Regions is reported in this month`s Proceedings of the Royal Society (Biological Sciences). British Antarctic Survey biologist David Barnes studied `battles` between rock-dwelling marine organisms... view more (2002-10-07)

Superfloods hit the capital @ London `Catastrophes` conference
Flooding of the world`s coastal lowlands has the potential to generate major future catastrophes. The melting of the great ice sheets in North America and Asia at the end of the last ice age caused extreme flood events that changed global climate and played an important role in human settlement and... view more (2002-08-17)

Scientific breakthrough will help protect astronauts and spacecraft

Oldest Antarctic ice core reveals climate history
Secrets of the Earth's past climate locked in a three-kilometre long Antarctic ice core are revealed this week in the journal Nature. The core from Dome C, high on East Antarctica's plateau, contains snowfall from the last 740,000 years and is by far the oldest continuous climate record obtained... view more (2004-06-03)

Desert dust enables algae to grow
Biologists from the Royal Netherlands Institute for Sea Research have demonstrated that desert dust promotes the growth of algae. Scientists had already assumed that the iron in desert dust stimulated algal growth, but this has now been demonstrated for the first time. The researchers have... view more (2003-12-19)

New laboratory to study the oceans and air
Almost two-thirds of the planet is ocean and this has a major impact on our lives. Now the University of East Anglia (UEA) will be home to the world's first facility dedicated to the study of chemical ocean-air interactions which are important in regulating Earth's climate. Examples include ocean... view more (2003-11-21)

International Dawn Chorus Day - Sunday 2nd May 2004
As nature lovers all over the world wake up to enjoy the enthusiastic sounds of birdsongs on International Dawn Chorus Day on 2 May, scientists at British Antarctic Survey's (BAS) Halley Research Station will listen to a very different Dawn Chorus. Each morning, as the Earth and its enveloping... view more (2004-04-29)

Methane gyrations last 2,000 years show human influnece on atmosphere
Humans have been tinkering with greenhouse gas levels in Earth's atmosphere for at least 2,000 years and probably longer, according to a surprising new study of methane trapped in Antarctic ice cores conducted by an international research team.   view more (2005-09-09)
