A chunk of ice the size of Amsterdam: how the calving of Greenland’s glaciers has changed since the 2010 Petermann Glacier event

A chunk of ice the size of Amsterdam: how the calving of Greenland’s glaciers has changed since the 2010 Petermann Glacier event

Thirteen years ago, a roughly 251 km2 chunk of ice (or 97 miles2) broke off Greenland’s Petermann Glacier. This Amsterdam-sized piece of ice was the largest to calve in the Arctic since 1962. The massive iceberg traversed the Nares Strait, which lies between Canada’s Ellesmere Island and Greenland, and into the northern part of Baffin …[Read More]

Imaggeo On Monday: High amplitude ‘V-shaped’ kink fold with axial plane cleavage

The Himalayan-Tibetan orogeny has been considered the youngest collisional fold belt in the Earth and a classic example of intercontinental collision orogeny. It is comprised of different litho-tectonic units manifested by normal/thrust faults and suture zones (Valdiya, K.S., 1977). The Himalayan region has experienced multifaced deformation, spectacular rock assemblages with high-pressure-temperature metamorphism, and an earthquake …[Read More]

100 years since we learned dinosaurs laid eggs, what do we know now?

An expedition to the Gobi Desert in Mongolia unearthed fossilized dinosaur eggs, in a nest, confirming that dinosaurs laid eggs like the reptiles that scientists at the time thought dinosaurs were. The find …[Read More]

Imaggeo On Monday: Nature’s impressionist painting

The image shows an incredible blend of colors in a natural cave in Kolob Canyons near Zion National Park, Utah. Formed by the oxidation of minerals lining the walls of the cave and snow melt, the sight feels like a natural inspiration for impressionist painting. This well-hidden gem is a lesser known treasure at the …[Read More]
