A team of Brazilian scientists has discovered a fossilized skeleton of what they believe is one of the world's oldest dinosaurs after heavy rains in the southern state of Rio Grande do Sul accelerated the natural...
The Andean Plateau in South America rises, on average, more than 4,000 meters above sea level, formed by orogenic uplift that began more than 20 million years ago. Orogeny occurs at convergent plate margins as compressed...

Antarctica sea ice melts to a record low

The Antarctic Ocean area covered by ice has shrunk to a record low, exposing the thicker ice shelves buttressing Antarctica's ground ice sheet to...

17-pound meteorite discovered in Antarctica

Antarctica is a tough place to work, for obvious reasons—it's bitterly cold, remote, and wild. However, it's one of the best places in the...

Antarctica’s emperor penguins could be extinct by 2100

Greater conservation efforts are needed to protect Antarctic ecosystems, and the populations of up to 97% of land-based Antarctic species could decline by 2100...

Scientists map heat beneath Antarctica’s icesheets

Researchers from the ARC Center for Excellence in Antarctic Science (ACEAS) at the University of Tasmania are helping predict future sea level rise by...

Antarctica’s ice shelves could be melting faster than we thought

A new model developed by Caltech and JPL researchers suggests that Antarctica's ice shelves may be melting at an accelerated rate, which could eventually...

Ice core taken in Antarctica contains sample of atmosphere from five million years ago

A team of researchers affiliated with multiple institutions in the U.S. has successfully pulled an ice core from Antarctica's Ong Valley that contains samples...

Antarctica’s only active volcano shows how CO2 allows volcanoes to form persistent lava lakes at the surface

Antarctica has long been a land of mystery and heroic feats made famous by the explorations of James Ross, Roald Amundsen, Robert Scott and...

Scientists discover a vast, salty groundwater system under the Antarctica ice sheet

A new discovery deep beneath one of Antarctica's rivers of ice could change scientists' understanding of how the ice flows, with important implications for...

Solar energy explains fast yearly retreat of Antarctica’s sea ice

In the Southern Hemisphere, the ice cover around Antarctica gradually expands from March to October each year. During this time the total ice area...
