Remote Sensing at the Permafrost Lab

 


Research Group Remote Sensing of Permafrost Landscapes

Remote sensing is key to detection, monitoring, and understanding spatial processes of permafrost change in remote high latitude regions. We recently embedded a research group in the Permafrost Laboratory focusing strongly on the remote sensing of environmental dynamics in permafrost landscapes. We are engaged in the Panarctic, but our current focus regions are Alaska and North Siberia. We are working with optical imagery on various scales from aerial imagery to MODIS data, LIDAR, IfSAR, GRACE, and via external collaborations started working with SAR data (TSX, ERS-2, PALSAR). Field work and ground truth in remote Arctic regions and under sometimes extreme environmental conditions (winter cold, snow storms, summer heat, mosquitoes...) are a crucial component of our remote sensing studies. Our work is closely coupled with the modeling efforts by Profs. V. Romanovsky and S. Marchenko, and Postdoctoral Fellow R. Daanen. Several additional projects by lab members include remote sensing analyses on the sidelines. Research Technician B. Cable supports many technical aspects of our group. Together we are working on a still virtual project 'Permafrost Watch' in which we try to incorporate remote sensing, ground data and modeling on an operational basis for distinct real-world applications.

Our group is continuously looking for undergraduate and graduate students with interest in permafrost, cryospheric change, Arctic climate impacts, modeling, and remote sensing / GIS applications. Exciting research themes are just waiting to be tackled at this new and rapidly growing frontier of Earth's cryosphere sciences.

 


Current projects

 


Permafrost Watch is a still virtual project that aims at combining remote sensing and field data streams with modeling of permafrost to operationally measure, monitor and predict physical permafrost parameters for distinct target regions relevant to decision makers in government and industry.
