Congratulations to Wenbo Wu *19 for receiving the American Geophysical Union’s Study of the Earth’s Deep Interior Graduate Research Award for his graduate research.
The Witwatersrand Basin in southern Africa began as a shallow sea about 3 billion years ago. Scientists analyze this water to learn how microbes make a living when trapped kilometers beneath the surface. DCO Deep Energy and Deep Life Community members: Thomas Kieft (NMT), Verena Heuer (UNI-Bremen), Esta van Heerden (UFS), Barbara Sherwood Lollar (UToronto), and Maggie C.Y. Lau and Tullis Onstott (Princeton) investigated the organic matter in fracture waters to find clues to how they survive.
Scientists have struggled to understand why there are hot spots in Volcanoes. New research chalks the mystery up to “dark magma”: deep underground pockets of red-hot molten rock that siphon energy from Earth’s core. “It’s a very provocative paper ... a bit speculative,” says Thomas Duffy, a geoscientist at Princeton University who was not involved with the study. “But it’s taking us in an important step on the road to understanding the deep Earth.”
