Seminar Series: Dust Deposition on Snow Research by Dr. Zoe Courville

Event Date: November 27, 2018

Date: November 27, 2018

Location: RM N119, The City College of Technology , 300 Jay Street Brooklyn NY 11201

Time: 1:00pm 

Presenter: Dr. Zoe Courville

The incorporation of dust, and other dark materials, onto snow can have profound impacts on the fate and timing of melt water from mountain snowpacks. Feedback processes initiated with dust deposition have implications for water resources in many areas around the world, and particularly in the southwest US. We have studied the micro- to macro-scale processes involved with the deposition of dust onto snow from a study plot in southwestern Colorado using a range of techniques, including micro-computed tomography (micro-CT) scanning to isolate dust particles, measurements of spectral reflectance of snow surfaces, combined with remote sensing imagery analysis, to determine the snow and dust grain scale processes occurring within the larger landscape. Results of this study, along with an overview of snow and ice research conducted at USACE ERDC and civil works and military application of this work, will be presented.
