Press Release - Icebergs A-72 and A-73 Calve from Larsen-D Ice Shelf

19 January 2021 — The Larsen-D Ice Shelf calved two more icebergs which are large enough to be named. The breakup occurred in mid-December 2020 from the northern part of Larsen-D approximately 150 nautical miles north of the recently named A-70 and A-71 icebergs. Similar to the A-70 and A-71 calving, it had been difficult to confirm whether these were icebergs large enough to be named or extremely old sea ice that had fasted to the ice shelf. Recent imagery showing surface topography typical of icebergs has allowed us to confirm these are indeed icebergs. The new iceberg A-72 is located at 69° 39' South, 60° 53' West measures 11 nautical miles on its longest axis and 4 nautical miles on its widest axis. The new iceberg A-73 is located at 69° 47' South, 60° 38' West and measures 9 nautical miles on its longest axis and 5 nautical miles on its widest axis.
