In this haunting image by Ruslan Eliseev, we see the sunken remains of the 76-ft Mar Sem Fin, a Brazillian boat that was used for scientific and educational expeditions. The boat, which sunk on April 7, 2012, lies at a depth of about 9 meters (30 ft) in Ardley Bay, Antarctica. Thankfully the crew was completely evacuated and nobody was hurt.
