Hugo is trying to refute some hypothesis postulated by a rival research group, yet he is unable to actually unearth the factual evidence behind this claim. Frustrated by the lack of transparency, he groans: How is it possible that I come across unhelpful references in peer-reviewed papers? Dear Hugo, The publishers don’t care. Not really. As long as alumni jot down some names and an annum in brack ...[Read More]

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]

Detrital zircons: how the age of a resistant mineral can help to reconstruct the climate of the past
Name of proxy detrital zircon geochronology Type of record provenance proxy Paleoenvironment any sedimentary environment in a geologically diverse and diagnostic area Period of time investigated any Period of the geological timescale of the Earth, during which sedimentary deposits were formed How does it work? Igneous rocks form through assemblages of minerals crystallising from melt. While ...[Read More]

GMPV for Sustainable Development – Geothermal Energy
GMPV and The Sustainable Development Goals In 2015 all United Nations Member States adopted a set of Global Goals, as a universal call to protect our planet, end poverty and ensure that all people can enjoy peace and prosperity. These are called the Sustainable Development Goals – 17 integrated goals aimed at addressing the challenges our society is currently facing considering social, economic, a ...[Read More]

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]
