  3. Four members of the scientific staff on board the D/V Glomar Challenger (ship) on Leg 42A of the Deep Sea Drilling Project in the Mediterranean Sea took time out for a coffee break after working with sedimentary core material. Left to right: Robert E. Garrison, University of California at Santa Cruz; Kenneth J. (Kenneth Jinghwa) Hsu, Geologisches Institu der E.T.H., Zurich, Switzerland; Maria Bianca Cita, Instituto di Gologia,Milano, Italy; and Daniel Bernoulli, Geologisch-Paleontologisches Institut der Universitat, Basil, Switzerland. Scripps Institution of Oceanography was the managing institution for Deep Sea Drilling Project under contract with the National Science Foundation (NSF). 1975.

  4. 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.

  5. Technician William J. Brennan, aboard the D/V Glomar Challenger (ship) helped place a new air gun into the water for a check before beginning Leg 51 of the Deep Sea Drilling Project in the harbor of San Juan, Puerto Rico. The air gun, which was a larger version of the bolt equipment the ship had used since 1968, was towed approximately 100 feet behind the ship and fired between 500 and 2,000 pounds of pressure at 10 second intervals. It was the sound source (in conjunction with a smaller air gun for better definition) for seismic profiling records. The larger gun, a 120 cubic inch PAR, provided deeper penetration. With these guns seismic records provided a reliable picture of sub-ocean bottom topography. November 1976.
