For our seasonal greetings this year, we would like to present the outreach team of the climate division. Our team has grown after the last EGU assembly, and this was highly visible in our increased number of blog postings throughout the year. We published 14 post in total! The team is responsible for writing and editing blog posts as well as finding motivated guest writers. We try to address all ...[Read More]
Tectonics and Structural Geology
Maria Vasilyevna Klenova (12 August 1898 – 6 August 1976): The polar scientist who was known as the mother of marine geology.
On the 12th of August 1898, Maria Vasilyevna Klenova was born to a working-class family in Irkutsk1. This city started as a military outpost in 1652, but had become a bustling city around the turn of the 20th century with around half a million inhabitants. In the year Maria was born, Irkutsk became connected to Europe by the infamous Trans-Siberian Railway. Maria did not stay in Irkutsk ver ...[Read More]

Earthquake of the month: Russia, deep earthquake M 6.4
November was not highlighted by a large event (> M 7). However, the TOP 3 of the largest earthquakes include a deep focus rupture on November 30th in the Tatar Strait between eastern Russia and Sakhalin Island (Figure 1). This earthquake (M 6.4) occurred at a depth of ~600 km according to different seismology agencies. The moment tensor representation shows an oblique mechanism with a dominant ...[Read More]

Beyond Tectonics: Fishing for Continents in the Furious Fifties and Roaring Forties
This edition of “Beyond Tectonics” is brought to you by Dr. Derya Gürer and Luca Magri. Derya is a Lecturer in Earth Sciences at The University of Queensland in Brisbane, and Adjunct Lecturer at the University of Tasmania, and Luca is a PhD student at the University of Tasmania in Hobart, Australia. In early 2020, they participated in a research voyage to one of the most remote places on the plane ...[Read More]

TS Must-Read – Riba (1976) Syntectonic unconformities of the Alto Cardener, Spanish Pyrenees: a genetic interpretation
In 1976 Oriol Riba published his paper on “Syntectonic unconformities of the Alto Cardener, Spanish Pyrenees: a genetic interpretation”, and despite appearing as a niche topic at first glance, it was voted as one of the papers in our Must-Read series. A major reason for that is that the paper presents a general model for syntectonic unconformities – an unconformity which illustrates both se ...[Read More]
Climate: Past, Present & Future
Deep Purple on Ice – Research on the Greenland Ice Sheet During the Pandemic
Insights into the EU project Deep Purple, fieldwork during the COVID-19 pandemic and doing research in a camp on the Greenland Ice Sheet. Written by Ph.D. students Rey Mourot (GFZ Potsdam), Laura Halbach (Aarhus University) and Eva Doting (Aarhus University). On maps, Greenland is shown as a massive white island. This vast ice and snow cover plays a vital role in reflecting incoming solar radiatio ...[Read More]

Mind your Head: Taking care of yourself during the Corona-virus crisis – Part 2
It has been many months since the first lockdown, in some countries about a year, in other countries perhaps eight months. A continuing learning curve, with many ups and downs. Now the end is slowly appearing on the horizon, with promises of vaccines, and several countries making definite plans on when and how to vaccinate. Still – it will take at least 6 months, quite possibly more, until it is o ...[Read More]
Stratigraphy, Sedimentology and Palaeontology
Fossils on screen
In these days fossils are becoming the new Hollywood stars as we are more and more pushed to use new -or sort of new- approaches for disseminating paleontology which pass through a screen. Technology is providing us with several ways to reach homes, colleagues throughout the world, or classrooms to share our research. The EGU General Assembly meeting itself will be online in 2021. Popular museums ...[Read More]
Soil System Sciences
The importance of our SSS (…Soil Support Staff!) #2
Last month, we launched the first in a monthly series of blog posts dedicated to highlighting the indispensable work carried out by our technicians, laboratory assistants, and research support teams. Soil Science is indebted to these key individuals and their essential, tireless efforts to keep laboratories afloat, maintain our facilities, carry out fieldwork, and make research happen. We kicked ...[Read More]

High-resolution biogeochemistry: Taking snapshots of past climate using mollusk shells
This is a solicited blogpost written by Niels de Winter. Now that the effects of rising anthropogenic CO2 emissions are starting to affect our everyday lives, accurate reconstructions of past climates become more and more relevant. These reconstructions help us to improve climate models used to project future global warming scenarios which in turn inform policy makers. The further we look back in ...[Read More]
