Imaggeo On Monday: Alps highest peak meets folded sea floor

During the late Jurassic, this dolostone was formerly at the sea floor, but after millions years of tectonic movements and natural forces, these rocks now appear at 3000m! Mont Blanc, the highest peak of the Alps is less than 20km away, and is visible in the background. Thank to the Alpine collision, this former sea floor was thrusted over gneiss and granite to make both geologists and mountaineer ...[Read More]

Imaggeo On Monday: Onsala Twin Telescopes

“The Onsala Twin Telescopes are part of the global geodetic Very Long Baseline Interferometry (VLBI) network. Radio telescopes all around the globe are observing extra-galactic radio sources simultaneously to determine Earth orientation parameters, source positions and station coordinates, as well as velocities. Geodetic Very Long Baseline Interferometry is used to maintain the International ...[Read More]

Imaggeo On Monday: Elephant Foot Glacier in Greenland from a Twin Otter perspective

“I was told that there will be a piedmont glacier on the way from Station Nord, a Danish military base in northeast Greenland, to our destination in no-man’s-land next to the 79°N Glacier. On half the way, we passed the beautiful Elephant Foot Glacier, named after its symmetric shape originating from the viscous flow of the ice. The glacier is located on a peninsula and connected to a small ...[Read More]

Imaggeo On Monday: Geodesy on Zugspitze

The Zugspitze Geodynamic Observatory Germany (ZUGOG) has been setup on the summit of mountain Zugspitze at an altitude of almost 3000 m during 2018 with the main scientific objective being a better understanding of seasonal and long-term mass redistributions in the European Alps. This knowledge is very important (e.g. with regard to water storage and its high sensitivity to climate change), but is ...[Read More]
