GeoTalk: Meet Larissa van der Laan, glaciologist and science-artist!

Hi Larissa, thankyou for spending time with us today! To break the ice, could you tell us a little about yourself and your research? Ha, I see what you did there. I’m Larissa, she/her, 29, and a PhD candidate at the Institute of Hydrology and Water Resources Management in Hannover, Germany. I’ve been fascinated by snow and ice since I was little, writing my first ever school report and ...[Read More]

Imaggeo on Mondays: The glacier surviving climate change

Human impacts on the climate are nowadays clearly discernible, and the changes to our climate that previously happened in geologic time scales are currently happening during the span of a human lifetime. Our planet is warming and temperature today is now more than 1°C higher than it was in the pre-industrial world and rises by about 0.15-0.2°C on average each decade. The dramatic effects of this r ...[Read More]

Imaggeo on Mondays: A walk at the glacier

In 2012 I had the opportunity to help lead a teaching excursion to the Norwegian archipelago Svalbard. On this trip, geography students from the Ruhr-University of Bochum in Germany had the chance to learn more about the nature of this fascinating island. In addition to Svalbard’s climatology and the wildlife, the region’s glaciology and geomorphology were the main topics we focused on. For exampl ...[Read More]

Imaggeo on Mondays: Robotics at the service of the polar science

This picture was taken in the Arctic in May 2018. It shows the unmanned marine vehicle Proteus in front of the tidewater glacier Conwaybreen in the Kongsfjorden in Spitsbergen in the Svalbard Archipelago. The front of tidewater glaciers is an almost vertical wall of ice standing over the sea where direct measurements are very critical due to the possibility of sudden fall of enormous blocks of ice ...[Read More]
