Geotalk is a regular feature highlighting early career researchers and their work. In this interview, we caught up with Christo Buizert, an assistant professor at Oregon State University in Corvallis, who works to reconstruct and understand climate change events from the past. Christo’s analysis of ice cores from Greenland and Antarctica helped reveal links between climate change events from the l ...[Read More]
The EGU General Assembly brings together geoscientists from all over the world to one meeting that covers all disciplines of the Earth, planetary and space sciences. The conference is taking place in Vienna on 7–12 April 2019, providing an opportunity for both established scientists and early career researchers to present their work and discuss their ideas with experts in all fields of the geoscie ...[Read More]

These ethereal, twisted ice sculptures litter the frozen shoreline of Tempelfjorden, Svalbard, giving the landscape an otherworldly feel and creating a contrast with the towering ice cliff of the glacier and the mountains behind. They are natural flotsam, the scoured remnants of icebergs calved from the Tunabreen glacier, washed up on the shoreline. These icebergs were calved from the Tunabreen gl ...[Read More]
Dear readers, today our blog will host Ryan Stone from Lambda Films. He will tell us his story and perspective behind the camera while documenting people’s lives constantly exposed to volcanic risk. If you want to get a quick taste of today’s content, just take a long breath and watch this video: https://www.lambdafilms.co.uk/video-production/an-eclipse/. Hello Ryan, Please tel ...[Read More]
Some of the most remarkable, marginal features of permafrost – palsas – are degrading and disappearing metre by metre from North European peatlands, and are driven close to extinction by the climate change. What are these permafrost features? A palsa is a peat mound with an icy core, which stays frozen throughout summer due to the insulating property of dry peat. These mounds can rise up to 10 met ...[Read More]
During the upper Carboniferous period (Namurian, Westfalian and Stephanian) large areas of central western Germany were covered by coastal swamp forests dominated by Lepidodendron und Sigillaria. Periodic marine and fluvial transgressions caused the swamps being regularly buried by siliciclastic material, resulting in up to 5500 m thick successions of alternating organic-rich and clastic-rich sed ...[Read More]
This photo depicts the famous ash cloud of the Icelandic volcano Eyjafjallajökull, which disrupted air traffic in Europe and over the North Atlantic Ocean for several days in spring 2010. The picture was taken during the initial phase of the eruption south of the town of Kirjubæjarklaustur, at the end of a long field work day. Visibility inside the ash cloud was within only a few metres. The erupt ...[Read More]
On September 15th, 2018, at 18:02 local time, NASA launched its newest satellite – the second generation Ice, Cloud and land Elevation Satellite (ICESat-2). ICESat-2 only contains one instrument – a space laser that fires 10,000 pulses per second to Earth to measure elevation. Its primary purpose is for monitoring the ever changing cryosphere, so naturally there are plenty of ice enthusiasts ...[Read More]
