Speaking: Dr. Ming Xiao
Content of Webinar: Drilling and sampling of permafrost; differences between subsurface exploration in permafrost regions and temperate regions; importance and basics of in-situ permafrost temperature measurements; visual classification of frozen soils (ASTM D4083); in-situ geophysical testing using multichannel analysis of surface waves (MASW), electrical resistivity tomography (ERT), and distributed acoustic and temperature sensing (DAS, DTS); laboratory testing of frozen soils.
Brief Introduction of Instructor: Dr. Ming Xiao is a Professor of Civil Engineering (with specialty in geotechnical engineering) in the Department of Civil and Environmental Engineering at Penn State. His current research focuses on permafrost degradation, permafrost coastal erosion, and their impacts on civil infrastructure and local communities in the Arctic. He is the President-Elect of the USPA and the Chair of USPA’s Permafrost Engineering Education Program (PEEP). He is a registered Professional Engineer (PE) in the States of California (since 2007) and Ohio (since 2005).
Format: The webinar is offered on Zoom. The webinar is 1 hour long, including a 50-min lecture and 10-min Q&A.
