“State of the ECS”: Getting back to normal…?

Matthew here! Since the end of the Summer, across Europe there were a few months of some kind of normality, and the ECS team enjoyed the freedoms that were on offer. Field work! In-person conferences! Actually seeing someone else in the office!?! As the winter draws in (how can it be December already?!?), and the future looks a bit more uncertain, we hope reading about what the team have been gett ...[Read More]

Tracing Atmospheric dustiness in the Permo-Carboniferous of northeastern Gondwana

Cyclic Permian carbonates above Carboniferous contain dust deposits, Central Alborz Mountains (Iran)

This blog summarizes two recent articles about dust in the Paleozoic. Planet Earth is presently undergoing a profound climatic turnover. Improved understanding of both the mechanisms contributing to the present climate change and its consequences for the biosphere, including human society, will not only provide the knowledge required to cope with its effects, but may also shed light on the forces ...[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]

Define and assess drought, the herculean challenge!

Define and assess drought, the herculean challenge!

The frequency and intensity of drought periods have increased since the 1950s over most land areas [1]. In fact, between 1998 and 2017, drought was the sixth natural hazard associated with disasters (4.8% of the total number of disasters) but the second in terms of the total number of affected people (33% of the total number of affected people), causing more than 21,000 deaths [2]. For example, in ...[Read More]

Will the ice break out? – a story from the farthest north ice trails

Man on snow machine looks bake to the canoe he is towing across ice.

"For over two decades, the sea ice group at the University of Alaska has worked with the community of Utqiaġvik, establishing an integrated observing network. This network includes local observations, a coastal radar system to monitor ice conditions, an in-situ mass balance site monitoring environmental change such as ice growth and snow cover, and the mapping of community sea ice trails." In thi ...[Read More]

Extensional tectonics at oceanic transform faults: a new perspective on plate tectonics

Extensional tectonics at oceanic transform faults: a new perspective on plate tectonics

Yu Ren is a PhD candidate at GEOMAR Helmholtz Centre for Ocean Research Kiel, Germany. He uses three primary tools to study marine tectonics: geomorphology, seismology, and numerical modelling. His PhD project is on the structural and tectonic characterization of oceanic transform faults.   Oceanic transform faults (OTFs), usually considered as first-order tectonic segmentation of mid-ocean r ...[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]
