SENSORChat: Go with the UPFLOW – detecting powerful motions deep within Earth’s interior

SENSORChat: Go with the UPFLOW – detecting powerful motions deep within Earth’s interior

“SENSOR” – stands for Seismological Experiments, Network Systems, Observations and Recovery In this blog series, curated by Chiara Civiero, we share news about recent or upcoming seismic experiments around the globe! Could you explain what your project is about? While downward mantle flow (subduction) is well constrained, a grand challenge in Earth sciences is to …[Read More]

Time & space of glaciers

Time & space of glaciers

People usually perceive space and time, comparing them to their own life Words such as “forever” and “until the end” appear in fiction But how can we imagine the space and time of the mountain glaciers whose existence goes beyond our usual perception? And why is it so important for us now? With this post, …[Read More]

The Sassy Scientist – Faulty Segments

The Sassy Scientist – Faulty Segments

`Segmentation fault’. One of the most annoying things ever to appear on our screens. Right up there with `fftw.h not found’. Compilation errors are the (rock-hard) bread and (rancid) butter of any of us that need to debug write codes. Tahina is deeply down the rabbit hole and asks: Why does my code not compile? …[Read More]

When weather extremes meet climate change: how do scientists attribute single events to climate change?

When weather extremes meet climate change: how do scientists attribute single events to climate change?

One of the main new points of the IPCC reports AR6 with respect to the previous ones is the increased confidence that global climate change induced by anthropogenic emissions is critically affecting the dynamics of weather extremes. For summer, and specifically over Europe, the AR6 report states that we are already observing prolonged periods of …[Read More]

Do lower mantle slabs contribute in generating the Indian Ocean geoid low?

Do lower mantle slabs contribute in generating the Indian Ocean geoid low?

The Indian Ocean Geoid Low is an enigmatic phenomenon in geodynamics. Many brain-storming hypotheses have been proposed in the last few decades to explain this geoid low. One popular idea argues that the high density lower mantle slabs contribute to this geoid low. Recent discoveries have shown that low-density anomalies from the African LLSVP region …[Read More]

AGU Hydrology Students talk JEDI, awards, and recognizing student success at AGU townhall

By David Litwin At the American Geophysical Union Fall Meeting in December 2021, the AGU Hydrology Section Student Subcommittee (H3S) convened a townhall “Coming Together After Being Apart…” where the AGU Hydrology Section leadership were available for questions from the community, updates on current activities, and plans for future section initiatives. The conversation seemed important …[Read More]

Imaggeo On Monday: Stands of Time

Imaggeo On Monday: Stands of Time

Within the heart of the Malagasy Hauts-Plateaux, the rolling grasslands are pitted by deep incisions locally referred to as lavaka (‘hole’ in Malagasy). These mass failure features provide vast quantities of terrestrial matter to local freshwater arteries, accounting for over 80% of the annual sediment load of the Betsiboka River. The collapse of the overlying …[Read More]
