North and South: Equal melting from each hemisphere raised ice age sea levels
The gargantuan volumes of meltwater that boosted sea levels during the most recent round of ice ages derived equally from ice sheets in the Northern and Southern Hemispheres.

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.

The Old Crowd: Minke whales have long thrived in Antarctic seas
Genetic studies of whale meat from Tokyo grocery stores appear to strengthen the case for protecting Antarctica's minke whales against renewed hunting.

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.

Wind Highways: Mosses, lichens travel along aerial paths
Invisible freeways of wind may account for the similarity of plant species on islands that lie thousands of kilometers apart.

Geologists take magnetic view through ice
A new map of the magnetic anomalies in Antarctica and the seafloor surrounding the continent is giving researchers a fresh tool to use in analyzing geologic features that lie hidden beneath thousands of feet of ice or storm-tossed seas.
