COMET scientist Juliet Biggs will receive the 2017 Geodesy Section Award at this year’s American Geophysical Union (AGU) Fall Meeting, to be held 11–15 December in New Orleans.

The award recognises Juliet’s outstanding contributions to the field of satellite geodesy for understanding both active volcanism and faulting.

On receiving the award, she said: “Many of the previous AGU Geodesy Section Award winners have been role models for me personally, and seeing my name among them is truly humbling.”

COMET researchers at the University of Oxford have estimated the total carbon emissions emanating from the Eastern Rift – the eastern branch of the East African Rift, a zone near the horn of East Africa where the crust stretches and splits.

The new study published in Geochemistry, Geophysics, Geosystems, led by COMET PhD student Jonathan Hunt, working alongside Tamsin Mather and David Pyle as well as colleagues from Oxford and Addis Ababa University, Ethiopia, extrapolates from soil carbon dioxide surveys to estimate that the Eastern Rift emits somewhere between 3.9 and 32.7 million metric tons (Mt) of carbon dioxide each year.

The research demonstrates how, even near some seemingly inactive volcanoes, carbon dioxide from melted rock seeps out through cracks in the surrounding crust.
