Seminar - Observing Arctic hydrology: The view from Space
This talk will explore ways in which remote observing techniques can be used to track the location, flow paths and fluxes of water in Arctic landscapes.
As Arctic temperatures have risen rapidly over the past century, complex changes have been observed in the high-latitude hydrologic cycle. Due to remote locations and sparse populations however, ground-based observations of Arctic hydrology have often been insufficient to characterise these changes. Satellite-based remote sensing offers an intriguing way to address some of the limitations of field-based monitoring.
Dr Pavelsky's research focused on the intersections between hydrology, satellite remote sensing and climate change. He works on scales ranging from the entire globe to a single large wetland, with a special interest in Arctic and Subarctic regions. Current research projects aim to address three questions:
(1) How can satellite remote sensing be used to understand the storage and movement of surface water?
(2) How accurately can regional climate models simulate hydrologic processes?
(3) How is anthropogenic warming impacting Arctic hydrologic and climatic systems?
