GeoTalk: Meet Rebekka Steffen, the Geodesy Division’s Early Career Scientist Representative

Hello Rebekka, thank you for taking the time to talk with us today! Could you introduce yourself to our readers? Hi. Thanks for giving me the chance to talk about my research and plans as ECS Rep for the Geodesy Division. I’m a researcher in Geodesy at Lantmäteriet, which is the Swedish mapping, cadastral, and land registration authority (I prefer the much shorter Swedish version 😉). I’m working i ...[Read More]

Imaggeo on Mondays: When boulders hitch a ride from glaciers

Glen More, on the Isle of Mull, Scotland, is a classic locality for studying glacial landforms and sediments. Here, two prominent ice-transported boulders stand guard at the head of the valley, left behind after the Loch Lomond Readvance (Younger Dryas stade), the final pulse of Quaternary glaciation in Scotland. Behind them in the characteristic U-shaped valley, hummocky morraines are littered wi ...[Read More]

Geosciences Column: How fast are Greenland’s glaciers melting into the sea?

Geosciences Column: How fast are Greenland’s glaciers melting into the sea?

The Greenland ice sheet is undergoing rapid change, and nowhere more so than at its margins, where large outlet glaciers reach sea level. Because these glaciers are fed by very large reservoirs of ice, they don’t just flow to the coast, but can extend many kilometres out into the ocean. Here, the ice – being lighter than water – will float, but remain connected to the ice on the mainland. This phe ...[Read More]

Imaggeo on Mondays: A dramatic avalanche from Annapurna South

The Annapurna massif is located in an imposing 55 km long collection of peaks in the Himalayas, which behave as a single structural block. Composed of one peak (Annapurna I Main) in excess of 8000 m, a further thirteen peaks over 7000 m and sixteen more of over 6000 m, the massif forms a striking structure within the Himalayas. Annapurna South (pictured in today’s featured image), the 101st talles ...[Read More]
