Now it remains to be seen where it will fluctuate!
This is now one of the largest icebergs ever recorded and its extension of 5800 square kilometers is similar to the island of Cyprus. The news of final detachment was given by British Midas project scientists jointly led by some universities along with the British Antarctic Survey, in order to monitor the evolution of the white continent in relation to climate warming. The separation was then confirmed by the images collected by the satellites
Iceberg A-68 has detached itself from the Larsen-C Ice Shelf in July 2017. Using satellites, scientists observed the A-68 iceberg starting to drift away from the Larsen-C, with open ocean clearly visible in the ~ 5 kilometre gap between the berg and the ice-shelf. Larsen-C Ice Shelf is the largest remaining ice shelf on the Antarctic Peninsula and the calving event reduced its total area by ~10%. The giant iceberg A-68 is about 5800 square kilometers and weighs more than a trillion tonnes.
With COSMO-SkyMed satellites, (the italian radar constellation of the Ministry of Defense and Italian Space Agency) , we will continuously monitor the trends of A-68 keeping our eye on it!
With COSMO-SkyMed it will be possible to follow it, thanks to its tasking flexibility (as close as few hours before satellite pass).
