A huge chunk of ice, measuring roughly 80km by 40km has broken off the Mertz Glacier in Antarctica and may contain the body of explorer Xavier Mertz. The tongue of the Mertz Glacier in Antarctica calved in February 2010. An iceberg pushed up against the tongue and knocked it off. The dislodged chunk measures roughly 80km by 40km. Steve Rintoul has just returned from the region where he was looking at the waters in the newly exposed region. The waters around Antarctica play an important role in climate, driving currents in the world’s oceans. Indeed the currents influence the storage of heat and carbon dioxide in ocean waters. It is thought the body of explorer Xavier Mertz still remains in the glacier tongue and is drifting in the southern ocean.
