Charles Davis Hollister

Born 18 Mar 1936; died 23 Aug 1999 at age 63.American marine geologist whose pioneering studies of the deep-sea floor revealed not tranquil depths but that strong currents and storms occur there. He started the development of the giant piston coring system and in the 1970's, documented the longest continuous record of ocean basin history in a single 100-ft core sample that contained a continuous 65 million-year-long record of ocean-basin history. He also made significant discoveries concerning ocean sediment transport and directed the High Energy Benthic Boundary Layer Experiment (HEBBLE). Also, he initiated the sub-seabed concept and led the international team that studied the scientific feasibility of isolating high-level radioactive material into sediments below the sea floor.
