Alpine rock instability events and mountain permafrost

Alpine rock instability events and mountain permafrost

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]

Image of the Week – Life in blooming melting snow

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]

Image of the Week — Cavity leads to complexity

  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]

A personal view on EGU 2019 – an edition like no other

This year Vienna was (for me) awfully cold. Sitting in the sun in the midst of happy conference attendees was definitively not an option at EGU this year. Due to the new EGU schedule with parallel sessions and longer oral sessions, making it until the lunch break was also a big challenge, at least for someone like me, who has more of a northern lifestyle. Luckily, this year posters were scheduled ...[Read More]

InSAR Norway: the big eye on Norwegian unstable rock slopes

InSAR Norway: the big eye on Norwegian unstable rock slopes

Marie Keiding is a researcher in the Geohazard and Earth Observation team at the Geological Survey of Norway. Together with her colleague, John Dehls, who is leading the project, she works to develop and operate the new mapping service called InSAR Norway. Before we start, let’s briefly describe what is InSAR. First, the Synthetic Aperture Radar (SAR) is a day and night operational imaging system ...[Read More]

Water vapor isotopes: a never ending story!

Water vapor isotopes: a never ending story!

Water stables isotopes are commonly exploited in various types of archives for their information on past climate evolutions. Ice cores retrieved from polar ice sheets or high-altitude glaciers are probably the most famous type of climate archives. In ice cores, the message about past temperature variations is conserved in the ice, formed from the snow falls whose isotopic composition vary with the ...[Read More]
