Two divers, one in an atmospheric dive suit (left) and the other in standard dive gear (right), prepare to explore the Lusitania shipwreck in 1935. Over the decades, diving gear has evolved and changed, and its role in marine research has expanded. Scuba and other forms of diving have allowed scientists to explore places and encounter species otherwise hidden from human eyes.
