GeoTalk: Meet Larissa van der Laan, glaciologist and science-artist!

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 snow and ice since I was little, writing my first ever school report and ...[Read More]

Imaggeo On Monday: Ice caves in high altitude karstic areas

Imaggeo On Monday: Ice caves in high altitude karstic areas

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 ground-ice ...[Read More]

Imaggeo On Monday: Chuquicamata copper mine, Chile

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 Martyn Unsworth, after the description on imaggeo.egu.eu.   Although much o ...[Read More]

Imaggeo On Monday: Green Energy of Kamchatka

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 the Kamchatka region, at the expense of using the richest stocks of thermal heat ...[Read More]

Imaggeo On Monday: New view on the Silk Road

When we were following the route of the Silk Road and heading to the Xinjiang province of China, this was what we saw. The large scale wind power plant brought some hope to this very old road. Hope that with all other renewable energies, it can become an answer to our sustainable future.   Description by Wenzhu Hou, after the description on imaggeo.egu.eu.   Imaggeo is the EGU’s online o ...[Read More]

Imaggeo On Monday: The tree that gave birth to a forest

Imaggeo On Monday: The tree that gave birth to a forest

This 10 centimetre giant is a pioneer of marine conquest. All summer, glassworts (Salicornia europaea) will be rhythmically swept by the tide, gradually trapping seaborne sediment on the shores of Aberlady Bay in Scotland. The resulting elevation of the mudflat marks the start of a race of growth against waves, currents and sea level rise, eventually leading to the development of a salt marsh. How ...[Read More]

Imaggeo On Monday: C/2020 F3 (NEOWISE) – a memorable moment

Around 17th July 2020, the core of the Neowise comet starting giving off a greenish-glow. At first I thought this strange colour was due to some glitch in my camera sensor (I used an entry-level DSLR), but other photos online also started reporting this greenish glow. It has since been speculated to be because of the formation of a new vent on the surface of the comet, discharging gaseous ions whi ...[Read More]
