UF Geological Sciences PhD student Stephanie James has been advancing new methods to use seismic noise to monitor seasonal changes in depth to ice in Alaskan sediments. With co-authors from Sandia National Laboratory and UF, she recently published a paper “Improved moving window cross-spectral analysis for resolving large temporal seismic velocity changes in permafrost” in Geophysical Research Letters. This paper was selected as a recent “Editor’s Highlight”.
Stephanie James completed her PhD in May and received a National Science Foundation Postdoctoral Fellowship to continue her research in this field. She will be collaborating with researchers at the US Geological Survey in Colorado.
