Geophysical imaging reveals topographic stress control of bedrock weathering.
Bedrock fracture systems facilitate weathering, allowing fresh mineral surfaces to interact with corrosive waters and biota from Earth's surface, while simultaneously promoting drainage of chemically equilibrated fluids. We show that topographic perturbations to regional stress fields explain bedrock fracture distributions, as revealed by seismic velocity and electrical resistivity surveys from...
متن کاملAdapting a Survey-class Auv for High Resolution Seafloor Imaging
Over the past four years, development work at the MIT AUV Lab focused on a vehicle that is now almost a decade old. “Xanthos,” one of the last surviving examples of the venerable Odyssey II series of AUVs (developed at MIT in the early 1990s), is a small, deep-rated, lowdrag vehicle originally intended for oceanographic survey work. In this project, the AUV Lab pushed the limits of the Odyssey ...
متن کاملFine-Scale Seafloor Survey in Rugged Deep-Ocean Terrain with an Autonomous Robot
The rugged mountainous regions of the deep seafloor hold both great scientific interest as well a host of difficult challenges for autonomous robots. Exploiting its abilities for precise navigation, trackline following, and bottom-following in rough terrain, the Autonomous Benthic Explorer (ABE) collected fine-scale bathymetry, magnetics, temperature, optical backscatter, and conductivity over ...

متن کاملInfiltration into fractured bedrock
[1] One potential consequence of global climate change and rapid changes in land use is an increased risk of flooding. Proper understanding of floodwater infiltration thus becomes a crucial component of our preparedness to meet the environmental challenges of projected climate change. In this paper, we present the results of a long-term infiltration experiment performed on fractured ash flow tu...
