Seminar by Andreas Max Kääb, GeoHyd/The Department of Geosciences, UiO:
Global clustering of recent glacier surges
Abstract:
Using global Sentinel-1 radar backscatter data we systematically map the locations of glaciers with surge-type activity during 2017–22. We find 107 surge-type events globally between 2017 and 2022, around 95 of which are on glaciers already known as surge-type. Our data reveal a pronounced spatial clustering in three regions, (i) Karakoram, Pamirs, and Western Kunlun Shan (~50 surges), (ii) Svalbard (~25), and (iii) Yukon/Alaska (~9), with only a few other scattered surges elsewhere. This spatial clustering is significantly more pronounced than the overall global clustering of known surge-type glaciers. The 2017–22 clustering may point to the climatic forcing of surge initiation.
The talk is in Aud 2 in the Geology Building. It is also possible to follow at Zoom.
