A diver explores a continental trench in Silfra, Iceland, in 2010. The picture won top honors in the “Divers” category of the fourth annual Deep Indonesia International Underwater Photo Competition, whose winning photos were released to the press earlier this month.

The competition awarded U.S. $35,000 in seven categories for the most “stunning” underwater photos taken around the world in 2010, according to a press statement. Judges included professional underwater photographers and magazine editors.
