US satellite protection scheme could affect global communications
A proposed US system to protect satellites from solar storms or high-altitude nuclear detonations could cause side-effects that lead to radio communication blackouts, according to new research.   view more (2006-08-15)

Study shows snowfall hasn't increased over Antarctica in last 50 years
An international effort to determine the variability of recent snowfall over Antarctica shows that there has been no real increase in precipitation over the southernmost continent in the last half-century.   view more (2006-08-11)

Overall Antarctic snowfall hasn't changed in 50 years
The most precise record of Antarctic snowfall ever generated shows there has been no real increase in precipitation over the southernmost continent in the past half-century, even though most computer models assessing global climate change call for an increase in Antarctic precipitation as... view more (2006-08-11)

Cosmic dust in ice cores sheds light on Earth's past climate
Each year nearly 40,000 tons of cosmic dust fall to Earth from outer space. Now, the first successful chronological study of extraterrestrial dust in Antarctic ice has shown that this amount has remained largely constant over the past 30,000 years, a finding that could help refine efforts to... view more (2006-07-31)

Cosmic dust in terrestrial ice
For the last 30,000 years, our planet has been hit by a constant rain of cosmic dust particles.   view more (2006-07-28)

NASA Study Finds Clock Ticking Slower On Ozone Hole Recovery
The Antarctic ozone hole's recovery is running late. According to a new NASA study, the full return of the protective ozone over the South Pole will take nearly 20 years longer than scientists previously expected.   view more (2006-06-30)

Eighty below and loving it: Montana State University scientists to get new cold lab
Half-million-year-old Antarctic ice, avalanche triggers, frost heaves in roads and the possibility of life in Martian ice caps are just a few of the research projects expected to find a home in a new cluster of labs planned for Montana State University.   view more (2006-06-28)

Boston university researchers develop new model of ice volume change based on Earth's orbit
Through dated geological records scientists have known for decades that variations in the Earth's orbit around the sun — subtle changes in the distance between the two — control ice ages.   view more (2006-06-23)

Global atmospheric carbon level may depend primarily on Southern Ocean
Circulation in the waters near the Antarctic coast may be one of the planet's critical means of regulating levels of carbon dioxide in the Earth's atmosphere, according to Princeton researchers.   view more (2006-06-23)

Climate History Rewritten: Arctic Ice an Early Arrival
For the first time, scientists have pulled up prehistoric geologic records from the frigid vault of the Arctic Ocean. One of the findings, evidence of glacial Arctic ice from 45 million years ago, recasts a critical chapter of global climate history.   view more (2006-06-01)

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)

Rapid temperature increases above the Antarctic
A new analysis of weather balloon observations from the last 30 years reveals that the Antarctic has the same 'global warming' signature as that seen across the whole Earth, but is three times larger than that observed globally.   view more (2006-03-31)

Arctic, antarctic melting may raise sea levels faster than expected
Ice sheets across both the Arctic and Antarctic could melt more quickly than expected this century, according to two studies that blend computer modeling with paleoclimate records.   view more (2006-03-24)

Polar neutrino observatory takes a big step forward
An international team of scientists and engineers has taken a major step toward completion of what will be the world's preeminent cosmic neutrino observatory, harnessing a sophisticated hot-water drill to build an observatory under the South Pole that eventually will encompass a cubic kilometer of... view more (2006-03-22)

Impact of Climate Warming on Polar Ice Sheets Confirmed
In the most comprehensive survey ever undertaken of the massive ice sheets covering both Greenland and Antarctica, NASA scientists confirm climate warming is changing how much water remains locked in Earth's largest storehouse of ice and snow.   view more (2006-03-09)

Antarctic ice sheet losing mass, says University of Colorado study
University of Colorado at Boulder researchers have used data from a pair of NASA satellites orbiting Earth in tandem to determine that the Antarctic ice sheet, which harbors 90 percent of Earth's ice, has lost significant mass in recent years.   view more (2006-03-03)

Antarctic snow inaccurate temperature archive
According to Dutch researcher Michiel Helsen, annual and seasonal temperature fluctuations are not accurately recorded in the composition of the snow of Antarctica. His research into the isotopic composition of the Antarctic snow has exposed the complexity of climate reconstructions.   view more (2006-02-16)

Thin tough skin, slow-growing gills protect larval Antarctic fish
Very thin but hardy, unblemished skin and slow developing gills appear to be keys to survival for newly hatched Antarctic notothenioids, a group of fish whose adults thrive in icy waters because of antifreeze proteins (AFPs) in their blood.   view more (2006-02-14)

Parachuting allows krill to eat and run
Antarctic researchers have recorded a novel behavior in krill that may help regulate greenhouse gases. Antarctic krill, one of the largest animal resources on Earth, parachute into the deeper layers of the ocean many times a night and sequester large amounts carbon in the process.   view more (2006-02-07)

Antarctic krill provide carbon sink in Southern Ocean
New research on Antarctic krill (Euphausia superba), a shrimp-like animal at the heart of the Southern Ocean food chain, reveals behaviour that shows that they absorb and transfer more carbon from the Earth's surface than was previously understood.   view more (2006-02-07)

Two new lakes found beneath Antarctic ice sheet
The Earth Institute at Columbia University-Lying beneath more than two miles of Antarctic ice, Lake Vostok may be the best-known and largest subglacial lake in the world, but it is not alone down there.   view more (2006-01-26)

2005 Was the Warmest Year in a Century
The year 2005 may have been the warmest year in a century, according to NASA scientists studying temperature data from around the world.   view more (2006-01-25)

El Nino events affect whale breeding
A thirty-year study by an international team of scientists found a strong relationship between breeding success of whales in the South Atlantic and El Nino in the western Pacific.   view more (2006-01-11)

Mission to Mars via Antarctica
As part of the Aurora Exploration Programme, ESA is considering participating in a human mission to Mars by the year 2030.   view more (2005-12-21)

NASA's AURA satellite peers into Earth's ozone hole
NASA researchers, using data from the agency's AURA satellite, determined the seasonal ozone hole that developed over Antarctica this year is smaller than in previous years.   view more (2005-12-07)
