Scientists from the British Antarctic Survey are apparently rushing to the site of the calving of the A68 iceberg to examine an ecosystem that has been hidden under the ice for more than 120,000 years (https://www.theguardian.com/environment/2018/feb/20/scientists-race-to-explore-antarctic-marine-life-revealed-by-giant-iceberg). The iceberg is reportedly 4 times the size of London and is detaching from the Larsen C ice shelf. It will be interesting to see what organisms have managed to live (and evolve?) in such a hostile environment but the magnitude of changes in sea ice in the Antarctic is somewhat worrying.
