TS Must-Read – Yin and Harrison (2000) Geologic evolution of the Himalaya-Tibetan Orogen

Yin and Harrison (2000) puts together an exhaustive review of three decades of geological and geophysical investigations on the Himalayan-Tibetan orogen. This research supports the orogenesis started during the Cenozoic between 70 and 50 Ma ago as a consequence of the Indo-Asian collision following the closure of the Tethys ocean between Laurasia and Gondwana. Yin and Harrison (2000) underlines th ...[Read More]

Cryo History – Extent of South Georgia Glaciation during the Last Glacial Maximum

Cryo History – Extent of South Georgia Glaciation during the Last Glacial Maximum

There has been considerable disagreement amongst researchers concerning the extent of South Georgia’s ice sheet during the Last Glacial Maximum (LGM). The sub-Antarctic islands (those below the polar front) may have been completely glaciated during previous glacials, and the last largest extent of the South Georgia ice sheet was during the LGM, about 21,000 years ago. But glaciologists don’t agree ...[Read More]

Geodynamics: It’s in the air we breathe!

and July 20, 2022

Have you ever wondered how Earth became habitable. In this week’s news and views, we have Fabio Capitanio, Associate Professor at Monash University sharing insights into the role Geodynamics in the evolution of Earth and life on it. Our planet has unique features which make it suitable for life. Understanding how the Earth became habitable is necessary to answer the most fundamental question ...[Read More]

A new glacier chronology from New Zealand

In this week’s blog, Levan Tielidze tells us about the new glacier history from the Southern Alps of New Zealand, an important piece of information to better understand the climatic history of Earth during the Quaternary, the current geologic period. Quaternary glaciations Geochronological dating of glacial moraines is useful for determining the extent and timing of past glaciation and for reconst ...[Read More]

“State of the ECS”: How was EGU 22 for you? Plus the new team!

Hello everyone! Hope you’re doing well, and that those of you who managed to make it to Vienna have now recovered, and that normal researcher life has now resumed (and isn’t too dull in comparison!) We hope you enjoyed all that the EGU GA had on offer, and that you were able to make it to some of the Seismology ECS events. I was very sad that I couldn’t be in two places at once s ...[Read More]

Photo of sunset behind the drilling vessel JOIDES resolution

This year I was lucky enough to be part of International Ocean Discovery Program (IODP) Expedition 390 – South Atlantic Transect I – aboard the research vessel JOIDES Resolution which spent two months, from April to June, out in the South Atlantic, drilling into and sampling the upper oceanic crust and sediments. I sailed as a petrologist and was responsible for describing how the basa ...[Read More]

Fire impacts on Earth across space and time: a discussion-driven conference

Fire impacts on Earth across space and time: a discussion-driven conference

Earth is the only known planet with fire activity – everywhere else, there is not enough oxygen for this process to occur. Since fire appeared on Earth many millions of years ago, it has played a key role in the development of plant adaptation and the distribution of ecosystems. However, the natural occurrence of fire changed with the onset of human evolution. The purposeful use of fire for ...[Read More]

The Sassy Scientist – Challenging Yourself

Single author papers. You have seen those. Early in your career you look at them and think “Wow! This person must be really smart to publish all by themselves”. Later on, your reaction shifts to “Ahah! Look at this person, publishing the tenth paper by themselves! Nobody wants to be associated with this stuff!”. Whether in awe, in derision, or because she is actually writing one of those, Loredana ...[Read More]

Lights out: cryosphere instruments perfectly placed to study solar eclipse

On 04 December 2021, only a handful of people in Antarctica were fortunate enough to experience a total eclipse. As well as spectacular views—including a brief window of totality that darkened the midnight sun for 2 minutes—this phenomenon is known to affect the flow of energy between the Northern and Southern hemispheres of the ionosphere. Because eclipses in Antarctica only happen once every ~20 ...[Read More]
