Fig. 1118 a) A sediment strength measunng probe deployed by ALUMINAUT at 6,000 ft The rings provide depth of penetration data and an accelerometer within a glass sphere 

 inside the cylindrical housing provides supporting information The glass sphere is retrieved by retracting the pin on the right which allows the sphere to surface (NAVOCEANO) 



b) STAR Ill's parabolic acoustic reflector transducer system was used to monitor reverberation of deep scattenng layers It also includes a stereo camera system {Gen. Dyn.) 



c) A diver adjusts an apparatus on ALUMINAUT which was used man expenment to measure sediment consolidation- When ALU/W/W-ALTs manipulator retracted one of the rings, a 

 steel ball of known dimensions and density fell to the bottom, a camera photographed the sediment cloud produced and subsequently, the imbedded ball itself (NAVOCEAf^) 



d) A close-up of the reversing thermometer racks shown in Fig. 11.17 The solenoids (left) released the thermometer rack from its upright position when activated. (WHOI)
