| Zusammenfassung |
| The British Antarctic Survey's Halley Research Station is located on the
Brunt Ice Shelf, Antarctica, where it is potentially vulnerable to calving
events. Existing historical records show that the Brunt Ice Shelf is
currently extended further into the Weddell Sea than it was before its last
large calving event, so a new calving event may be overdue. We describe three
different possible future scenarios for a large-scale calving event on Brunt
Ice Shelf. We conclude that currently the most threatening scenario for the
Halley Research Station is a calving event on the neighbouring Stancomb-Wills
Glacier Tongue, with subsequent detrimental consequences for the stability of
the Brunt Ice Shelf. Based on available data, we suggest an increasing
likelihood of this scenario occurring after 2020. We furthermore describe
ongoing monitoring efforts aimed at giving advanced warning of an imminent
calving event. |
