Satellites capture first-ever gravity map of tides under Antarctic ice
Ohio State University scientists have used minute fluctuations in gravity to produce the best map yet of ocean tides that flow beneath two large Antarctic ice shelves.   view more (2005-12-05)

New ice cores expand view of climate history
Two new studies of gases trapped in Antarctic ice cores have extended the record of Earth's past climate almost 50 percent further, adding another 210,000 years of definitive data about the makeup of the Earth's atmosphere and providing more evidence of current atmospheric change.   view more (2005-11-28)

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)

Seafloor creatures destroyed by ice action during ice ages
The ice ages made massive changes to the Earth's landscape. But what was happening below the ice in the oceans?   view more (2005-10-18)

Link between tropical warming and greenhouse gases stronger than ever, say scientists
New evidence from climate records of the past provides some of the strongest indications yet of a direct link between tropical warmth and higher greenhouse gas levels, say scientists at the University of California, Santa Barbara.   view more (2005-10-14)

Ocean invaders in deep time
Much has been made of the economic impacts of recent biological invasions, but what are the implications of invasions in deep time? Luiz Rocha leads geneticists who time travel through ocean environments.   view more (2005-10-14)

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)

Scientific breakthrough will help protect astronauts and spacecraft
A breakthrough by a team of British, US and French scientists will help protect astronauts, spacecraft and satellites from radiation hazards experienced in space.   view more (2005-09-08)

Snowball Antarctica - early Drake passage opening led to global change
New results shed light on how Antarctica became the icy, barren continent that we know today.   view more (2005-08-31)

Burning asteroids may play 'more important climate role than previously recognized'
Dust from asteroids entering the atmosphere may influence Earth's weather more than previously believed, researchers have found.   view more (2005-08-26)

Freeze-dried mats of microbes awaken in Antarctic streambed, says U. of Colorado study
An experiment in a dry Antarctic stream channel has shown that a carpet of freeze-dried microbes that lay dormant for two decades sprang to life one day after water was diverted into it, said a University of Colorado at Boulder researcher.   view more (2005-08-10)

New window into ancient ozone holes
British researchers have hit on a clever way to search for ancient ozone holes and their relationship to mass extinctions: measure the remains of ultraviolet-B absorbing pigments ancient plants left in their fossilized spores and pollen.   view more (2005-08-10)

Collapse of Antarctic Ice Shelf Unprecedented
The Antarctic Peninsula is undergoing greater warming than almost anywhere on Earth, a condition perhaps associated with human-induced greenhouse effects.   view more (2005-08-04)

Discovering an ecosystem beneath a collapsed Antarctic ice shelf
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.   view more (2005-07-19)

Warmer air may cause increased Antarctic sea ice cover
Predicted increases in precipitation due to warmer air temperatures from greenhouse gas emissions may actually increase sea ice volume in the Antarctic's Southern Ocean.   view more (2005-06-30)

Deep sea algae connect ancient climate, carbon dioxide and vegetation
Assistant Professor Mark Pagani in the Department of Geology and Geophysics at Yale and his colleagues mapped the first detailed history of atmospheric carbon dioxide between 45-25 million years ago based on stable isotopes of carbon in a National Science Foundation study reported in Science... view more (2005-06-23)

Scripps Studies Provide New Details About Antarctic Iceberg Detachment
A multifaceted research effort by scientists at Scripps Institution of Oceanography at the University of California, San Diego, and their colleagues has resulted in several important new findings about Antarctica and the changing dynamics of its ice structure.   view more (2005-06-14)

Scientists use meteors to investigate climate change and giant waves at the 'edge of space'
A new research radar based in Antarctica is giving scientists the chance to study the highest layer of the earth's atmosphere at the very edge of space.   view more (2005-05-23)

Antarctica - an awakening giant?
The crucial role that Antarctica plays in global climate change and its future contribution to sea-level rise was highlighted today by Professor Chris Rapley, Director of British Antarctic Survey (BAS). Speaking at an international convention on climate change in Bonn, Germany* he presented a... view more (2005-05-19)

***Changed embargo time***Rising sea levels could be 'cancelled out' by increased snowfall
A paper published today in Science shows that the largest ice sheet in the world, the East Antarctic Ice Sheet, is growing due to increased snow fall. This growth partly mitigates the sea level rise caused by melting glaciers in other areas, especially Greenland.   view more (2005-05-17)

Global task force to save the albatross wins backing of The Prince of Wales
The Prince of Wales and record-breaking sailor, Ellen MacArthur, are together to trumpet global efforts to save one of the world's most endangered yet iconic birds.   view more (2005-04-26)

Carbon dioxide role in past climate revealed
Researchers at the British Antarctic Survey (BAS) and the University of California, Santa Cruz have discovered that Earth's last great global warming period, 3 million years ago, may have been caused by levels of CO2 in the atmosphere similar to today's.   view more (2005-04-11)

175th birthday of the German polar explorer Eduard Dallmann
2005 marks the 175th birthday of Eduard Dallmann, a pioneer of German Antarctic research. Through his expeditions, Dallmann, who was born in Blumenthal (now part of Bremen) contributed significantly to the knowledge about Antarctica. He named numerous island groups and straits. From 1873 onwards,... view more (2005-03-10)

Extinction threats grow as sea governance rules ignored
Those who rule the ocean waves are being named and shamed today for their role in failing to prevent the near extinction of the albatross.   view more (2005-03-03)

Antarctic ice shelf retreats happened before
The retreat of Antarctic ice shelves is not new according to research published this week (24 Feb) in the journal Geology by scientists from Universities of Durham, Edinburgh and British Antarctic Survey (BAS).   view more (2005-02-23)
