Una spedizione internazionale di scienziati studierà da vicino l'ecosistema dopo il distacco del mega iceberg A68 in Antartide. Si tratta della prima missione da quando la massa di ghiaccio da un trilione di tonnellate si è separata dal blocco principale, noto come "Larsen C", ha fatto sapere la British antarctic survey (BAS).
Secondo gli esperti si tratta di un'occasione unica per studiare l'ecosistema marino rimasto nascosto per quasi 120'000 anni sotto l'iceberg. Ma il tempo stringe: "È importante arrivare rapidamente prima che l'ambiente muti per l'effetto dei raggi del sole", ha spiegato la biologa Katrin Linse che dirige la missione.
Gli scienziati esploreranno la zona e raccoglieranno diversi campioni dalla fauna. L'obiettivo è realizzare una "fotografia" della misteriosa vita sotto la calotta polare, ma anche studiare gli effetti dei cambiamenti climatici.
