Title: What’s in a Gigaton? Using detailed mapping of Greenland’s ice to better resolve and communicate ice sheet dynamics
Presenter: Michalea King, University of Washington

Abstract: Recent advances in remote sensing capabilities have provided observations over the polar regions in unprecedented detail, including the ability to monitor ice flow at high temporal resolutions. We combine several independent optical and radar data sources to resolve weekly to seasonal variability in glacier speed and dynamic ice loss across the Greenland Ice Sheet and discuss how the timing and duration of short-term acceleration events can offer clues to underlying glacier dynamics. We then apply similar velocity mapping methods to regions beyond the calving front to track the spatiotemporal variability of rigid mélange (an aggregate mixture of sea ice and icebergs moving uniformly) and understand how its presence impacts glacier calving. Combined with quarterly DEMs built from ICESat-2 altimetry data, we also gain insight into how readily glacier fronts reach near-flotation on a seasonal basis, which likely plays a role in how well mélange controls the timing of seasonal glacier retreat. Finally, the social implications of polar research make scientific outreach and public polar literacy paramount. We highlight how improved remote sensing capabilities and data visualization can be powerful tools for engaging audiences with the concept of rapid ice sheet change and with the impacts of climate change on polar landscapes.

Unfortunately we need to postpone today’s scheduled webinar due to illness. The webinar has been rescheduled for Thursday, June 8th, 2-3p ET.
If you’ve already registered for the webinar, you don’t need to do anything, the zoom link you received when you registered should still allow you to join on June 8th.
If you haven’t yet registered, you’re in luck! You’ve got an extra 3 weeks to sign up at this link:
Apologies for the last minute change, and I hope that you’ll be able to join us for the rescheduled presentation on Thursday, June 8th.
Thanks!
Justin
