Hidden cryosphere: dynamics of ice aprons and ice caves
Abstract: Ice aprons and ice caves are two poorly known components of the cryosphere that show contrasting responses to environmental conditions (but both in a poor state…). Ice aprons – thin ice bodies on steep Alpine rock walls – are highly sensitive to atmospheric warming and have undergone rapid retreat in recent decades, increasing rockfall hazards and threatening ancient ice archives as well as mountaineering routes. In contrast, ice caves are underground systems where ice could persist for centuries/millennia due to specific microclimatic conditions. Although more thermally buffered and often located outside permafrost zones, they are also showing striking signs of destabilization. Together, these features highlight the diversity of little-known and vulnerable cryospheric bodies.

The GeoHyd seminars are normally held in Auditorium 2 in the Geology Building, Blindern (map) but it is also possible to follow some of the seminars on Zoom.
Videolink to the lectures will be sent to the e-mail list geohyd-alle@geo and geohyd-info@geo. If you want to subscribe to the geohyd-info@geo mailing list send an email to Anita Sørlie.
About the seminar series
The talks in GeoHyd Lunch Seminar Series are offered by the Section for Geography and Hydrology (GeoHyd), Dept. of Geosciences, University of Oslo. The seminars are announced as lunch seminars so bring your lunch if you want to.
The seminars are open for everyone interested, and especially students are welcome.
