Atmospheric Rivers: A blanket for Antarctic winter sea ice

Atmospheric Rivers: A blanket for Antarctic winter sea ice

The mysterious appearance and disappearance of the Weddell Polynya, a giant hole in the sea ice cover, has long puzzled scientists. Recent work reveals that the polynya is initiated and maintained by gigantic and formidable atmospheric currents: atmospheric rivers! Read on to find out more… Each year, approximately 15 million square kilometers of ice forms in the Southern Ocean around Antarctica d ...[Read More]

The Sassy Scientist – Welcome to Hotel California

The Sassy Scientist – Welcome to Hotel California

Congratulations Glenn! You survived your socially distanced PhD defence and after three months in your mum’s spare room you are raring to go, chomping at the bit, and approaching the start line for the next stage of your academic career. Having spent the last eight years in education, it’s time to start a new job! What should I do on my first day at work in a new place? Dear Glenn, Whe ...[Read More]

TS Must-Read – Ramsay (1980) Shear zone geometry: a review

TS Must-Read – Ramsay (1980) Shear zone geometry: a review

Ramsay’s 1980 important contribution is a practical and theoretical handbook about shear zones, where the reader can find a detailed classification of shear zones, their description, and mathematical explanation. A definition of the concept of shear zones opens the article, followed by the shear zones classification into three types, namely brittle (e.g., Fig. 1a), brittle-ductile (e.g., Fig ...[Read More]

Rift linkage and rotating microplates

Rift linkage and rotating microplates

2020 left your head spinning? This week Derek Neuharth from GFZ Potsdam introduces us to the spinning microplates that can be found in extensional plate boundaries such as the East African Rift System and the East Pacific Rise. Divergent plate boundaries Microplates are enigmatic features that form in the boundaries between tectonic plates. Generally, plate boundary dynamics are divided into three ...[Read More]

Community Effort to explore the Papers that shaped Tropospheric Chemistry

Community Effort to explore the Papers that shaped Tropospheric Chemistry

The genesis of the idea to explore the influence of certain papers on shaping the field of tropospheric chemistry came when editing a textbook chapter I had written a decade earlier. As I edited it I thought, what really is new; text-book worthy over the last 10 years? In some senses what is text-book worthy at all? These type of questions inspired me to think about where atmospheric chemistry has ...[Read More]

TS Must-Read – Brace and Kohlstedt (1980) Limits on Lithospheric Stress Imposed by Laboratory Experiments

TS Must-Read – Brace and Kohlstedt (1980) Limits on Lithospheric Stress Imposed by Laboratory Experiments

In 1980 Brace and Kohlstedt published a short paper that constrains the strength of continental lithosphere by extrapolating laboratory measurements of rock strength to geological conditions. Their approach follows earlier work by Goetze and Evans (1979) and relies on two key considerations. First, the brittle strength is given by the frictional strength of rocks following Byerlee’s law (Bye ...[Read More]

The importance of our SSS (…Soil Support Staff!) #3

Happy New Year! It’s January, and time for us to continue our monthly series of blog posts dedicated to highlighting the great work carried out by technicians, laboratory assistants, and research support staff in soil science.  This month, we sat down (virtually, of course) with Jonathan J. Gottlieb (J.J.), the Head of the Laboratory for the Conservation of Waterlogged, Organic, Archaeological mat ...[Read More]

Imaggeo On Monday: “Smoking” peaks of the Patagonian batholith

Imaggeo On Monday: “Smoking” peaks of the Patagonian batholith

The indigenous name of the 3405 meter high Fitz Roy mountain in Patagonia, on the border between Argentina and Chile, is frequently translated as “smoking mountain”. This photo may visually explain an origin of this name. On the day the photo was taken, vortices downwind of the peak drew warmer, humid air from below, forming banner clouds at the leeward site of the Fitz Roy mountain an ...[Read More]

The Sassy Scientist – The Twelve Steps (of Academia)

The Sassy Scientist – The Twelve Steps (of Academia)

Furious yet disillusioned by a bunch of anonymous reviewers, of which most have provided zero insight through their nugatory reviews and displaying unambiguous bias towards a non-inflammatory, well-worded and a scientifically substantiated manuscript, Txabi demands to know: Why are many reviewers still insisting on anonymity? Dear Txabi, There is indeed such a segment of the academic community, wh ...[Read More]

GeoPolicy: EGU science for policy: what’s coming up in 2021?

There were a lot of big changes to the EGU’s science for policy programme in 2020 with many of our activities, such as the annual science for policy event and science-policy pairing scheme, moving online. But 2021 promises to be an even bigger year with a greater number of opportunities to engage and activities becoming even more accessible! So, if you haven’t engaged with science for policy befor ...[Read More]
