Two articles in this week's issue of Science feature Bristol Scientists
Steve Sparks and Juliet Biggs are co-authors on a paper that discusses needs for the better monitoring of volcanoes. Although there have been significant improvements in geophysical methods for monitoring and modelling, there is still a need for further technique development. More importantly, most volcanoes worldwide are not effectively monitored, especially those in developing countries.
Bruno Dhuime and co-workers argue that the onset of subduction-driver plate tectonics may have started ~3 billion years ago. Their work is based on the analysis of oxygen isotopes in zircons, which reveals systematic changes in the balance between the generation of new continental crust and reworked ancient crust. Ex-Bristol researchers Chris Hawkesworth and Craig Storey are co-authors on the paper.
We would like to congratulate both groups.
