| Popis: | The recent likely implosion of the Titan deep ocean submersible's spherical pressure hull has elevated interest and concerns on the nature and dynamics of such events. Here we report on studies of three deep-ocean implosions of 43 cm diameter glass instrument housings, made by Benthos Inc. The goal of the studies was to determine the effects on their associated cabling, moorings, and other spheres as part of a larger deep sea observatory. High resolution acoustic profiles were also measured for two of the three implosions, allowing us to infer some of the dynamics and kinematics of the events. The mechanical forces on the ancillary mooring hardware during the entire implosive/explosive event were found to be most probably dominated by the explosive shock wave following the initial infall. A syntactic float at a distance of 16 m from the implosion center was probably shattered by such a shock wave, but 3 glass instrument housings apparently survived within a distance of 6 m from the same implosion.
