GEOL 393/394 projects advance despite pandemic! Most students presented mid semester talks in person on October 16 to a socially distanced select few, while most of the audience attended via Zoom.

Senior Adam Margolis received a CMNS Alumni Network Undergraduate Summer Research, Travel and Educational Enrichment Award to help pay for field camp but had to alter plans due to Covid-19.

Venus is still churning! Laurent Montesi and colleagues from ETH Zürich shows that at least 37 ring-like structures on Venus called coronae are probably active today.

Congratulations! Professor James Farquhar has been awarded the title of Distinguished University Professor.

Using a new machine learning algorithm, seismologists Doyeon Kim and Ved Lekic detected pervasive scattering near the core-mantle boundary and discovered a ultralow-velocity zone beneath Marquesas Islands.
