Geophysical Infrastructure Studies: Earthen Dams and Abandoned Mine Lands
Geophysical Infrastructure Studies is comprised of a series of applied research projects focused on studying site-specific problems at earthen dams and abandoned mine lands. An appropriate suite of geophysical methods are chosen for each project and its particular goals and geologic environment. These projects are funded by the federal agencies in charge of the risk mitigation, assessment, or...
ROSETTA-Ice — Ross Ice Shelf, Antarctica
ROSETTA-Ice is a large, NSF-funded, multi-disciplinary and multi-institutional project with several major goals focused on the full ice shelf system of the Ross Ice Shelf that include the ice, underlying seafloor bathymetry, and ocean interaction. Methods include the first comprehensive LC-130-based airborne geophysical survey of the Ross Ice Shelf to measure ice thickness and accumulation (ice...
Using In Situ IR Spectroscopy Measurements of Vermiculite Insulation to Determine Its Origin
The goal of this study was to determine if in situ near-infrared reflectance measurements, using portable spectrometers, could be used to reliably identify the source of vermiculite ore and therefore its potential to contain asbestos. The method developed can be used to determine vermiculite insulation's source and estimate its potential amphibole content, providing low-cost analysis with onsite...
