LOESS IN TRANSLATION

LOESS IN TRANSLATION

Loess is a mineral, aeolian deposit with a range of definitions in literature, which class it as either a sediment, soil, or rock. Some classic texts suggest that “loess is not just the accumulation of dust” [1], and it must include additional processes such as loessification, calcification, pedogenesis, and in-situ weathering. The definition adopted depends on the scientific background and the qu ...[Read More]

How Open Science may help us during and after the pandemic

How Open Science may help us during and after the pandemic

As Hedding et al. (2020) indicate, it is “not business as usual” for higher education across the globe. There are many testimonies by scientists who are struggling to work while their children are stuck at home during the coronavirus pandemic (Langin, 2020). Indeed, it is very complex to stay at home to raise and home-school kids and remain productive as an academic while living through a pandemic ...[Read More]

Imaggeo On Monday: Great Sand Dunes Sunset

Imaggeo On Monday: Great Sand Dunes Sunset

On a late afternoon in Colorado’s Great Sand Dunes, the sun came out from behind the clouds for a brief moment before it went behind the horizon, illuminating the stoss side of an eroding dune. Sand originated from lacustrine deposits in the San Luis Valley; the Sangre de Cristo mountains, which can be seen in the background, provided a source of some of the sand. This image therefore illust ...[Read More]

Using Milankovitch Cycles to create high-resolution astrochronologies

Using Milankovitch Cycles to create high-resolution astrochronologies

This year marks the 100th anniversary of Milutin Milankovitch’s first paper about Earth’s climate. Milankovitch argued that the amount of solar radiation Earth receives, and hence its climate, varies cyclically as its orbit changes due to gravitational tugs from the other planets. His climate theory fell into disrepute during the 1950’s but was rehabilitated in the 1970’s.   Today, many peopl ...[Read More]

Earthquake of the month: Samos-Izmir earthquake

Earthquake of the month: Samos-Izmir earthquake

On October 30th, a strong earthquake with Mw 7.0 occurred in the Aegean Sea, between the main cities of Samos in Greece and Izmir in Turkey. The hypocenter location and focal mechanism suggest shallow depth (~10 km) and normal faulting on the E-W plane. This is in agreement with the tectonic setting where an N-S extension is dominant. Moreover, the rupture propagates near the Menderes Graben in We ...[Read More]

Imaggeo On Monday: Erosion and suspension

Imaggeo On Monday: Erosion and suspension

This image shows bottomset beds from the Kerinitis Gilbert-type delta. The Pleistocene delta uplifts along the active southern margin of the Corinth rift in Greece. A bottomset bed is one where layers of sedimentary material lying along the bottom of a body of water near the point of entry of a stream are subsequently covered by foreset and topset beds in the formation of a delta. Thus in this ima ...[Read More]

GeoPolicy: How geoscience can support the European Green Deal

Earlier this year, the EGU hosted the Integrating science into the EU Green Deal event in collaboration with the Intergroup on Climate Change, Biodiversity and Sustainable Development to outline how the geosciences can most effectively support the European Green Deal and ensure its ambitious biodiversity and zero-pollution targets are reached. The event provided policymakers, scientists and indust ...[Read More]

A new European effort to better understand extreme weather

A new European effort to better understand extreme weather

Extreme weather events routinely have detrimental socio-economic impacts around the globe. In fact, weather-related events make up over 90% of natural disasters worldwide [1]. In the new millennium, the frequency of many extreme weather events such as droughts and high temperatures, has systematically exceeded the levels seen in the 1980s and 1990s [1], and anthropogenic climate change may further ...[Read More]

Imaggeo On Monday: Micro and Nano composition

This image shows benthic foraminifera species of Favulina hexagona (Williamson, 1848) together with nanofossils enclosed inside the shell hexagons. This modern foraminifera species was found in the sediment core retrieved from the western slope of the Rio Grande Rise (western South Atlantic).   Description by Liubov Kuleshova, after the description on imaggeo.egu.eu.   Imaggeo is the EGU ...[Read More]

First-time convening an EGU session? Some advice from the Early Career Scientists.

First-time convening an EGU session? Some advice from the Early Career Scientists.

With the most recent call for sessions for the next European Geosciences Union General Assembly, a diverse provisional programme has been put together. If you have been assigned your first EGU session as a convener – congratulations! But what happens now? Early Career Scientists representatives Andrea Madella (GM), Anna Gülcher (GD), and Tommaso Alberti (NPG) discuss what it’s like to conven ...[Read More]
