Bow first by Giuseppe Suaria. The Russian research vessel Akademik Tryoshnikov leans its bow against the Mertz Glacier’s snout in Eastern Antarctica. The photo was taken moments before deploying Ropos, a remotely operated underwater vehicle, under the glacier tongue to investigate the melting of the ice-sheet after a piece of ice protruding 100km (62 miles) out into the Southern Ocean broke away from the main body of the tongue in 2010
