A University Centre in Svalbard (UNIS) Glaciology student examines the calving front of the Paulabreen glacier [in Spitsbergen, Svalbard], taking advantage of sea ice in the Rindersbukta fjord to safely approach the front. Paulabreen is a surge-type glacier, which means that it periodically switches between long periods of slow, stable flow to short-lived periods of very fast flow during which it ...[Read More]
Rockfalls, rock slides and rock avalanches in high mountains The terms rockfall, rock avalanche and rockslide are often used interchangeably. Different authors have proposed definitions based on volume thresholds, but the establishment of fixed boundaries can be tricky. Rockfall can be defined as the detachment of a mass of rock from a steep rock-wall, along discontinuities and/or through rock bri ...[Read More]
Should scientists actively approach policymakers in order to guide their decision-making processes, or is it the policymakers’ responsibility to seek scientific advice? In the first of the Great Debates at this year’s European Geosciences Union General Assembly in Vienna a mixed panel of policymakers and geoscientists tried to answer who should be responsible for making sure that science was used ...[Read More]
The new snow melting season has just started in the mountains of Europe and will last, in many alpine places, until the end of June. Weather in the middle of April is changeable. In the last few days sub-zero air temperatures have prevailed in the mountains during the day. In a frame of an international research project, me (Charles University) and Daniel Remias (Applied University Upper Austria), ...[Read More]
Each month, Jesse Zondervan picks his favourite posts from geoscience and development blogs/news which cover the geology for global development interest. Here’s a round-up of Jesse’s selections for the last month: California seems to be overdue for earthquakes, meaning there has been a so-called earthquake ‘drought’ in the last century. Paleoseismic studies show that this hiatus is unprecedented i ...[Read More]
Lucie Parsons, a ten-year old girl from the small village of Walkington, in England, is on a personal mission to save the environment from plastic pollution. After seeing on the BBC Blue Planet II documentary how litter in the ocean is damaging ecosystems, she decided to take action. Now she gives talks and is co-researcher in her mother’s PhD on climate change and the youth voice. Lucie has come ...[Read More]
The annual division meeting for Hydrological Sciences is the place to get updated on the latest developments of our division. It was great to see that hundreds of you attended. For those that did not attend (or for those that appreciate a reminder of what happened), here are some of the highlights: The Hydrological Sciences Division has a new president: Maria-Helena Ramos will serve as the preside ...[Read More]
Establishing a human presence on Mars is increasingly seen by space agencies and private organizations as the horizon frontier in human space exploration. These long-duration missions however, impose a high degree of technological, operational, physical and psychological challenges. Mars analog habitats, such as the Mars Desert Research Station (MDRS) in Utah (U.S.) are established to conduct fiel ...[Read More]
A 10km-long, 4-km-wide and 350m-high cavity has recently been discovered under one of the fastest-flowing glaciers in Antarctica using different airborne and satellite techniques (see this press release and this study). This enormous cavity previously contained 14 billion tons of ice and formed between 2011 and 2016. This indicates that the bottom of the big glaciers on Earth can melt faster tha ...[Read More]
We tend to think of glaciers as spotless pristine settings. But “if plastic is everywhere, why not on the surface of glaciers?” This occurred to Roberto Sergio Azzoni, a professor of environmental science and policy at the University of Milan in Italy, who decided to find the answer to this question for himself. At the European Geosciences Union General Assembly in Vienna, Azzoni and his team pres ...[Read More]
