Changes in the ice shelves surrounding the Antarctic continent are responsible for most of its current contribution to sea-level rise. Although they are already afloat and do not contribute to sea level directly, ice shelves play a key role through the buttressing effect. But which ice shelf regions are most important for this? The role of ice-shelf buttressing In architecture, the term “buttress” ...[Read More]
Narrabeen–Collaroy Beach in New South Wales, Australia, just north of Sydney, is home to one of the longest-running shoreline-measurement programmes in the world. With colleagues at the University of New South Wales (UNSW) Sydney, Eli Lazarus, an associate professor in geomorphology at the University of Southampton, UK, has been analysing over 40 years of data from Narrabeen–Collaroy to better und ...[Read More]
This is the first post of “Talking hydrology”, an interview-based series of posts in the HS Blog that present the experience and personal views of hydrologists and people interested in talking about hydrology. The “Talking hydrology” series is edited by the team of the HS blog together with Leonie Kiewiet (University of Zurich, Switzerland). Here, we will talk about experimental hydrol ...[Read More]
The earliest continents played a fundamental role on Earth’s habitability. However, their generation is still not understood, and it requires an integrated approach between petrology and geodynamic modelling. In a new study, Piccolo and co-workers developed a method to handle the effects of chemical evolution on the geodynamic processes. They show that the production of the earliest felsic c ...[Read More]
by Rémy Bossu, Laure Fallou, Sylvain Julien-Laferrière, Matthieu Landès, Julien Roch, Fréderic Roussel, Sébastian Soriat and Robert Steed I set the area of interest, and then tried to adjust the magnitude threshold. Either the threshold was too high and I did not get information for the earthquakes that I felt, or it was too low and I got tens of notifications a day for earthquakes that nobody not ...[Read More]
Water Underground creator Tom Gleeson prepared this quick research video (with no more than a toothbrush, a file holder, and a doughnut, in one take!) for the Ripples project meeting at the Stockholm Resilience Centre, that was held in April. In this video, he talks about using doughnut economics for linking water planetary boundaries and UN Sustainable Development Goals. Display "Linking wat ...[Read More]
The EGU General Assembly 2019 took place in Vienna last month, drawing more than 16,000 participants from 113 countries. This month’s GeoRoundUp will focus on some of the unique and interesting stories that came out of research presented at the Assembly! Major Stories Glacial disappearing act in the European Alps New research from a team of scientists estimated the future of all glaciers within th ...[Read More]
EGU is a bit like a music festival. Maybe not as crowded as the Donauinselfest, but you’ll definitively experience some of this type of event classic features: dilly-dallying a lot about what to see next, losing your friends and setting up more or less detailed meeting points, buying overpriced food and beverages. And if in the right place at the right time, you might even see some actual “rock st ...[Read More]
Following her presentation at the European Geosciences Union General Assembly in Vienna, I caught up with geomorphologist and environmental detective Annegret Larsen from the University of Lausanne, Switzerland, about beavers, baffling sediments and a case she’s been solving for the past seven years. Back in 2012 the German geomorphology community was seriously debating the source of buried black ...[Read More]
