Compositional Anomalies Complicate Our Model of Mantle Convection

AGU Editors' Vox | 20 November, 2024
Plate tectonics is a part of mantle convection. However, planetary evolution includes both thermal and compositional effects. During seafloor spreading, for example, the upper mantle material is fractionated into basaltic crust and a harzburgite layer. Recent seismological studies and geodynamic models suggest that when oceanic plates are recycled back into the mantle, the associated depth-dependent density differences can cause chemical layering around the 660 kilometers phase transition.

How Fast?

Open Mind | 20 November, 2024
A comment on the last post mentioned that if the world is warming at 3.5°C per century (another way of saying 0.035°C/yr), then we'll hit 4°C by the end of this century. Are we really warming the planet that fast? ... Continue reading ??'...

Are Rogue Argo Floats Skewing Ocean Salinity Data Products?

AGU Editors' Vox | 19 November, 2024
Starting in 2015, an increasing number of salinity sensors on Argo floats, a key component of the ocean observing system, have shown a tendency to drift towards higher salinity levels. Although the affected salinity data are flagged with quality control markers, analyses that fail to exclude these raw data may lead to biased and elevated salinity estimates.

Skiphosoura – ‘solving’ the transition to pterodactyloids

Dave Hone's Archosaur Musings | 18 November, 2024
I'm delighted that today I have a new paper out with a really exciting new pterosaur, that I think adds an awful lot to our understanding of pterosaur evolution, as well as the animal itself being rather interesting. It's often fairly easy to say that a new find 'fills a gap in the fossil record' but some gaps are much bigger than others, or a situation is rather complex that can be clearly resolved with the right fine (or at least, provide an interesting new hypothesis). To follow through this new find and its implications, we need to start with a short bit of pterosaur history and evolution.

Tourism and Distant Fires Affect Antarctica’s Black Carbon Levels

AGU Editors' Vox | 18 November, 2024
Antarctic tourism is increasing each year, the vast majority by ship. Though this allows people to enjoy the continent's stunning landscapes, a new study reveals how this rise combined with forest fires in the Southern Hemisphere causes seasonal changes in black carbon levels.

Sergio Mendes and the Consumer Surplus of Music Streaming

Inkstain (John Fleck) | 17 November, 2024
Last's night's DJ John Show in the HF living room traced the history of Mas Que Nada, the '60s pop hit by Sergio Mendes and Brasil 66. Its roots in my pantheon of beloved music stem from its moment - KFI, the mid-1960s pop radio that ran as the background soundtrack of my childhood home. There was a bunch of Brazilian pop making the crossover to our hi-fi back then - Antonio Carlos Jobim's Wave, Astrud Gilberto's breathy Girl from Ipanema, though I'm pretty sure it was Herb Alpert's Girl that I first heard. Alpert's South of the Border was the handful of LP's the Fleck family owned.
