Scott Polar Research Institute - Physical Sciences Seminar

Seminars on polar physical sciences are held at the Scott Polar Research Institute during the Michaelmas, Lent and Easter terms. The seminars typically take place on Wednesdays between 16.30 and 17.30 and are held in the main lecture room, which can be accessed via the polar museum. Doors are open to public and all are welcome.

# Wednesday 13th March 2019, 4.00pm - Dr Penny How, University of York
Integrating Photogrammetry and Computer Vision into the study of Glacier Change
Venue: Lecture Theatre, Scott Polar Research Institute

Retreating glaciers and ice sheets provide a significant contribution to sea level rise, which will affect future populations and their activities. Accurate sea level projections are needed in order to best inform policy makers, but these projections are limited by our current understanding of the dynamics and processes that control ice loss. Techniques in Photogrammetry and Computer Vision are growing as a viable approach for obtaining highly detailed records of glacier change, and are presented here to demonstrate its future potential in the field of Glaciology. This includes its uses in deriving glacier velocities, identifying supraglacial lake drainage events, monitoring meltwater outflow, and examining calving dynamics at marine-terminating glaciers. From this, we will introduce our new project using historical photographs to analyse glacier change in the pre-satellite era, in collaboration with the Scott Polar Research Institute.
