Abstract

These folders contain geophysical data from Yosemite's Mariposa Grove of Giant Sequoias, site of the Bedrock Cluster of NSF's Critical Zone Collaboration Network. These folders contain ground penetrating radar (GPR) and seismic refraction tomography (SRT) data, which are associated with Anya Gupta (anyagup@vt.edu) MS thesis that aims to visualize giant sequoia roots using noninvasive geophysical methods. This project is funded by NSF grant EAR-2012353. Seismic imaging reveals spatial variability in soil and weathered bedrock, while GPR can non-invasively resolve root features. This knowledge may provide a framework for developing management strategies to enhance sequoia resilience under intensifying drought conditions, and highlights the role that GPR can play in protected ecosystems where root exhumation or deep coring is not possible.

Note: GPR data can be viewed using the open-source ground penetrating radar processing and visualization software GPRPy (Plattner 2020).
