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]

Timeline of historical highlights of the EGU Hydrological Sciences Division

Do you know when the Hydrological Sciences Division had their first Early Career Scientist representative? Or who the division president was in 2016? Check the answers below, where we list these and other historical highlights over almost 20 years of the Hydrological Sciences (HS) Division. Overall, the most striking fact is certainly the steady growth …[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

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]

TS Must-Read – Caine et al., 1996 Fault zone architecture and permeability structure

Caine et. al. (1996) is a cornerstone paper which describes, compares and quantifies brittle fault zones and their permeability (fluid flow) properties from observations. Doing so, the paper initiates the accumulation of information on the permeability of brittle fault zones described previously (Randolph and Johnson 1989; Scholz 2019; Byerlee 1993). The study begins by defining …[Read More]
