Changing atmospheric conditions may contribute to stronger ocean wave activity on the Antarctic Peninsula

A new study provides important details on the extent of sea ice, which can protect ice shelves from the impacts of ocean storms, in the Antarctic Peninsula.

Avalanches more complex than previously thought

Avalanches can throw up a powdery cloud of snow as they violently charge down mountains, obscuring their inner workings from scientists. But new observations of artificially-triggered avalanches in Switzerland’s Vallée de la Sionne have penetrated this powdery veil.

Researchers make first map of thawed areas under Greenland Ice Sheet

NASA researchers have helped produce the first map showing what parts of the bottom of the massive Greenland Ice Sheet are thawed – key information in better predicting how the ice sheet will react to a warming climate. Knowing whether Greenland’s ice lies on wet, slippery ground or is anchored to dry, frozen bedrock is essential for predicting how this ice will flow in the future, but scientists have very few direct observations of the thermal conditions beneath the ice sheet.

Post-wildfire erosion can be major sculptor of forested mountains

Erosion after severe wildfires can be the dominant force shaping forested mountainous landscapes of the U.S. Intermountain West, new research suggests. After the 2011 Las Conchas fire in New Mexico, soil and rock eroded from burned watersheds more than 1,000 times faster than from unburned watersheds nearby, the new study found. Most of the erosion happened in the first year after the fire.
