Annual ridges and troughs (called wave ogives) are formed as the ice of the Gates Glacier (in Alaska’s Wrangell Mountains) flows through a steep icefall. Down-glacier, as the ice melts, the rushing meltwater is funnelled into streams, carving ice canyons as it flows, but ultimately directed by these topographic constraints. Description by Allen Pope, …[Read More]
Each month we feature specific Divisions of EGU and during the monthly GeoRoundup we will be putting the journals that publish science from those Divisions at the top of the Highlights roundup. For December, the Divisions we are featuring are: Cryospheric Sciences (CR), Soil System Sciences (SSS) and Tectonics and Structural Geology (TS). They are served by …[Read More]
Hi Larissa, thankyou for spending time with us today! To break the ice, could you tell us a little about yourself and your research? Ha, I see what you did there. I’m Larissa, she/her, 29, and a PhD candidate at the Institute of Hydrology and Water Resources Management in Hannover, Germany. I’ve been fascinated by …[Read More]
High altitude karstic environments often preserve permanent ice deposits within caves, representing a lesser-known portion of the cryosphere. Despite being not so widespread and easily reachable as mountain glaciers and ice caps, ice-caves preserve a great deal of information about past environmental changes and paleoclimatic evolution. Since one of their main characteristics is to have …[Read More]
This month’s GeoPolicy blog post introduces the European Science-Media Hub (ESMH) along with its key initiatives. It also takes a deeper dive into the organisation through a Q&A that we were thrilled to have with the Head of the European Parliament’s Scientific Foresight Unit Theo Karapiperis and the coordinator of the ESMH Svetla Tanova-Encke. …[Read More]
Each month we feature specific Divisions of EGU and during the monthly GeoRoundup we will be putting the journals that publish science from those Divisions at the top of the Highlights roundup. For November, the Divisions we are featuring are: Energy, Resources and Environment (ERE), Nonlinear Processes in Geoscience (NP) and Seismology (SM). They are …[Read More]
Aerial view of the Chuquicamata copper mine in Northern Chile. This is the largest open pit copper mine in the world by volume (at the time of sharing). At this location the copper and molybdenum is extracted from a porphyry deposit that was formed beneath a volcano in the Andean subduction zone. Description by …[Read More]
The Mutnovsky Geothermal Power Plant is the largest geothermal power plant in Russia (the time of writing). It is located near to volcanic mountain Mutnovsky at altitude of 800 m and has a capacity of 50 MW. The Mutnovsky Geothermal Power Plant has resolved the problem of raising the stability of the power supply for …[Read More]
This week EGU announced the launch of an open call for members of a new Biodiversity Task Force to help EGU interact with European policymakers through it’s official Policy Priority Area ‘Biodiversity’. But what is a policy Task Force? What kind of work is involved? And are you eligible to apply to be a member? …[Read More]
