Antarctica’s gaining ice in some spots
Large portions of Antarctica are storing more snowfall than they once did.

Icy Heat: Satellites look at heat flow through Antarctica’s crust
Using satellite observations of Earth's magnetic field, scientists can estimate the amount of heat flowing upward through Earth's surface under kilometers-thick ice.

Ozone hole might not recover until the year 2065
The ozone-free zone that develops high in the atmosphere over Antarctica each summer as the result of the presence of chlorine- and bromine-containing chemicals may not heal until 15 years later than previously projected.

What’s Going on Down There?
In a 10-year, global effort, researchers exploring the unknowns of marine life have found bizarre fish, living-fossil shrimp, giant microbes, and a lot of other new neighbors.

Letters from the August 6, 2005, issue of Science News
Empty threat? “Empty Nets: Fisheries may be crippling themselves by targeting the big ones” (SN: 6/4/05, p. 360) reads as if there is something to be alarmed about. By selectively catching large fish, we have reduced “the mean size [of food fish to] one-fifth of what it was.” This is not cause for alarm. It […]

Cool Birds
Emperor penguins go to such extremes to cope with life in Antarctica that they've inspired interesting science as well as a hit movie.

Spores record changes in ozone concentration
Decreasing concentrations of atmospheric ozone over Antarctica have triggered changes in the spores of a plant that grows in the region, a trend that could give scientists insight into ancient extinctions.

Enceladus: Small but feisty
Close-up observations of Saturn's tiny moon Enceladus reveal that its south pole is hotter than its equator and that the icy satellite continues to undergo eruptions.

Volume of glaciers and ice caps is estimated
New topographic data have enabled scientists to estimate the volume of water trapped in the ice caps and glaciers outside of Antarctica and Greenland and to predict how high the sea level would rise if this ice melted.

Big quakes can free grounded icebergs
Data gathered by equipment installed on an immense iceberg off Antarctica suggest that the ground motions spawned by large, distant earthquakes can free such bergs to float again.
