When carbon emissions break nature: icebergs and their feedback to climate change

When carbon emissions break nature: icebergs and their feedback to climate change

The largest iceberg in the world, named A-76, about 170 km long and 25 km wide, is drifting away from the Ronne pack ice in Antarctica. A76, originally spotted by the British Antarctic Survey (BAS), a British polar research organization with a base nearby, will wander and melt in the Weddell Sea, according to a statement released Wednesday, May 20, by the European Space Agency. Several studies are ...[Read More]

It’s not you, it’s me(lange): ice shelf break-up triggered by mélange and sea-ice loss

Between March and May 2007, a total of ~2,445 km2 (equivalent to over 17 football pitches) of ice mélange (a mixture of sea-ice types, icebergs and snow) and part of Voyeykov Ice Shelf in East Antarctica rapidly broke up. Observations of the timing and triggers of such events are relatively rare in East Antarctica, compared to ice shelves on the Antarctic Peninsula. Recent work highlights the impo ...[Read More]

First BG Campfire with special guests from the Soil System Sciences Division!

We are excited to announce the 1st Biogeosciences Division Campfire event! The spirit of our campfire events is to bring together the biogeoscience community, irrespective of career stage, to discuss new BG research-relevant ideas and tools with one another. The aim of this welcoming, informal and inclusive BG virtual campfire will be to widen our research network and foster support within the BG ...[Read More]

The importance of our SSS (…Soil Support Staff!) #6

It’s May, and here at Soil System Science HQ we’re calming down after a busy yet fascinating fortnight at the General Assembly. Over the course of two weeks, we enjoyed many thousands of soil science presentations – each one representing a great contribution to our knowledge and understanding about the soil system. Of course, we should never forget that much of that research would not have b ...[Read More]

The Supercontinent Cycle

The Supercontinent Cycle

From orbital, to climatic, to tectonic evolution, many aspects of the Earth’s dynamics feature high degrees of cyclicity and episodicity, which can give us important insights into how the Earth’s works. The supercontinent cycle is an example capturing the Earth’s grandest scales and this week EGU geodynamics blog editor Tobias Rolf takes a closer look at it. Pangaea. This is a familiar term to eve ...[Read More]

Features from the Field: S-C fabrics

As we have seen in previous Features from the field posts, structural fabrics are both informative and spectacular. But many structural geologists will list a shear zone fabric, such as mylonite, as their favourite! As Samuele, Hannah and I wrote in a previous post, shear zones are regions of intense deformation where rocks have accommodated an extremely high amount of strain and that strain has b ...[Read More]

Meet the new Geodesy Division President

Now that you know who the new ECS Reps are. Who else is part of the Geodesy Division Team? The outgoing president Johannes Böhm did an excellent job for the last four years. Now Annette Eicker has taken over in April as she was elected as the new president of the Geodesy Division. But who is Annette? We asked her a few questions about her work within the EGU, but also about her research and what s ...[Read More]
