Imaggeo on Mondays: Sand and snow on the Tibetan Plateau

Roughly 50 million years ago, the Eurasian and Indian continental plates began to crash into each other, dramatically changing the landscape of modern-day Asia. The force of the collision caused the Earth to scrunch together at the zone of impact, subsequently forming the Himalayan mountain range. However, to the north of the crash, a stretch of the Earth uplifted without bunching up or wrinkling; ...[Read More]

Imaggeo on Mondays: Up close and personal with Svalbard glaciers

A University Centre in Svalbard (UNIS) Glaciology student examines the calving front of the Paulabreen glacier [in Spitsbergen, Svalbard], taking advantage of sea ice in the Rindersbukta fjord to safely approach the front. Paulabreen is a surge-type glacier, which means that it periodically switches between long periods of slow, stable flow to short-lived periods of very fast flow during which it ...[Read More]

First evidence of microplastics on mountain glaciers

But “if plastic is everywhere, why not on the surface of glaciers?” This occurred to Roberto Sergio Azzoni, a professor of environmental science and policy at the University of Milan in Italy, who decided to find the answer to this question for himself. At the European Geosciences Union General Assembly in Vienna, Azzoni and his team pres ...[Read More]
