Jerry Bode, center, Dennis Graham (with headphones) and Phil Stott, (right) are on the fantail of D/V Glomar Challenger (ship) pulling in a hydrophone streamer, part of the ship's seismic profiling equipment, prior to drilling at Site 415 on Leg 50 of the Deep Sea Drilling Project in the Atlantic Ocean off Morocco. The hydrophone array, some 300 feet long, at the end of a 1,000-foot cable had to be retrieved before the vessel could stop and drilling and coring could start. The seismic profiling equipment, which uses sound waves as an energy source, looks at the structure of the sediment below the sea floor and records the echoes electronically on a recorder in the Electronics Laboratory aboard ship. 1976.
