OCEAN FLOOR SYMPOSIUM

DURING THE PERIOD 26--29 JULY 1971 AN INTERNATIONAL SYMPOSIUM ON THE ENGINEERING PROPERTIES OF SEA-FLOOR SOILS AND THEIR GEOPHYSICAL IDENTIFICATION WAS HELD IN SEATTLE, SPONSORED BY UNESCO, THE NATIONAL SCIENCE FOUNDATION, AND THE UNIVERSITY OF WASHINGTON. THE CONFEREES STRESSED THE NEED FOR NEW AND MORE THEORETICAL METHODS OF DETERMINING THE PHYSICAL PROPERTIES OF OCEAN SOILS. ONE SET OF SPEAKERS PROPOSED A NONLINEAR MODEL DESCRIBING THE RHEOLOGICAL STRESS-STRAIN-TIME BEHAVIOR OF THESE SOILS, AND OUTLINED DYNAMIC AND STATIC EXPERIMENTAL PROCEDURES FOR DETERMINING THE NONLINEAR ELASTIC AND VISCOUS SOIL PARAMETERS ASSOCIATED WITH THIS MODEL. OTHER SPEAKERS EMPHASIZED THE NEED FOR EXTENSIVE IN SITU DETERMINATION OF OCEAN SEDIMENT STRENGTH AND COMPRESSIBILITY AND THE CORRELATION OF FIELD DATA WITH LESS EXPENSIVE LABORATORY TESTING METHODS. THE KEYNOTE ADDRESS, TITLED "SEA-FLOOR EVOLUTION, CONTINENTAL DRIFT, PLATE TECTONICS, AND SEA-FLOOR SPREADING," SOUGHT TO CREATE REALIZATION OF THE NEED FOR THE COMMON TALENTS OF GEOLOGISTS AND ENGINEERS IN LOCATING STABLE STRUCTURES ON THE OCEAN FLOOR. A COMMON MOTIF OF THE SYMPOSIUM WAS THE RELATIVE MERIT OF MANNED AND INSTRUMENTAL EXPLORATION OF INNER SPACE. I. E. MIKHALTSEV (INSTITUTE OF OCEANOLOGY, USSR ACADEMY OF SCIENCES) DISCUSSED THE ADVANTAGE OF OPERATING ON THE SEA FLOOR RATHER THAN AT THE PHASE AND STORM INTERFACE OCCUPIED BY SURFACE VESSELS. HIS PAPER AND OTHERS STRESSED THE IMPORTANCE OF TELEVISION AS A MEANS OF CONTROLLING BOTH MANNED AND UNMANNED DEVICES.
