Imaggeo on Mondays: America’s dead sea

Imaggeo on Mondays: America’s dead sea

On the blog today, Jennifer Ziesch, a researcher at the Leibniz Institute for Applied Geophysics, takes us on a tour of the Great Salt Lake, located in the north of Salt Lake City (Utah). Did you know it is one of the largest salt water lakes in the world? The large salt lake and Salt Lake City, named after the lake, lie on a flat plain about 1300 m above sea level. The salt lake is bordered to th ...[Read More]

Image of the Week – Apocalypse snow? … No, it’s sea ice!

Sea ice brine sampling is always great fun, but sometimes somewhat challenging ! As sea water freezes to form sea ice, salts in the water are rejected from the ice and concentrate in pockets of very salty water, which are entrapped within the sea ice. These pockets are known as “brines”. Scientists sample these brines to measure the physical and bio-geochemical properties, such as: tem ...[Read More]

GeoPolicy: Making a case for science at the United Nations

GeoPolicy: Making a case for science at the United Nations

This month’s GeoPolicy is a guest post by the International Council for Science (ICSU). Based in Paris, the organisation works at the science-policy interface on the international scale. Here, Heide Hackmann, Executive Director at ICSU, highlights key initiatives ensuring science is present within the United Nations (UN) and explains how ICSU and the scientific community can support these pr ...[Read More]

Minds over Methods: Sensing Earth’s gravity from space

Minds over Methods: Sensing Earth’s gravity from space

How can we learn more about the Earth’s interior by going into space? This edition of Minds over Methods discusses using satellite data to study the Earth’s lithospere. Anita Thea Saraswati, PhD student at the University of Montpellier, explains how information on the gravity of the Earth is obtained by satellites and how she uses this information to get to know more about the lithospe ...[Read More]

Imaggeo on Mondays: Deep in the Himalayas

The Himalayas: vast, formidable and home to the Earth’s highest peaks. The mountain range stretches inexorably through Indian, Bhutan, Nepal, China (Tibet) and Pakistan separating the Tibetan Plateau to the north from India’s alluvial plains to the south. India, as we know it today, started life much further south, as an island not far off the coast of Australia. It was separated from ...[Read More]

Geosciences Column: Africa’s vulnerability to climate change

Climate change is set to hit the nations of the Global South the hardest.

Ravaged by armed conflicts, a deep struggle with poverty, poor governance and horizontal inequality, some parts of Africa and other Global South regions are arguably the most vulnerable to the impacts of climate change. Largely reliant on natural resources for sustenance, current and future changes in temperatures, precipitation and the intensity of some natural hazards threaten the food security, ...[Read More]

Image of the Week – Supraglacial debris variations in space and time!

There is still a huge amount we don’t know about how glaciers respond to climate change. One of the most challenging areas is determining the response of debris-covered glaciers. Previously, we have reported on a number of fieldwork expeditions to debris-covered glaciers but with this Image of The Week we want to show you another way to investigate these complex glaciers – numerical modelling! Deb ...[Read More]

EGU’s Geodesy Division needs a new early career scientist voice

EGU’s Geodesy Division needs a new early career scientist voice

In the run-up to the general assembly in 2017, The geodesy division is looking for a fresh early career scientist (ECS) to take over the role of the ECS-representative. But what comprises being an ECS-representative? And where can you sign up? Early career scientists represent a significant share of the EGU general assembly attendees. It is therefore desirable to involve this group not only as par ...[Read More]

Image of the Week – On the tip of Petermann’s (ice) tongue

5th August 2015, 10:30 in the morning. The meeting had to be interrupted to take this picture. We were aboard the Swedish icebreaker Oden, and were now closer than anyone before to the terminus of Petermann Glacier in northwestern Greenland. But we had not travelled that far just for pictures… Petermann’s ice tongue Petermann is one of Greenland’s largest “marine terminating glaciers”. As the name ...[Read More]
