Development of Seismo/Acoustic Implosive Source

这个海洋科学仪器开发项目将开发和测试使用静水压力而不是炸药的声震源。内爆装置由一端有孔的压壳组成。在部署之前，用特殊的陶瓷板覆盖孔。在深度处，板块断裂，引起内爆，从而产生低频声信号，用于海底研究应用，如处理浅层剪切速度结构和短折射剖面。将要进行的工作包括工程测试和海上试验，以比较来自其他类型声源的声信号。拟议的内爆装置将比爆炸物更安全，并且不会受到监管限制的阻碍。

9712605 Dorman This ocean sciences instrumentation development project will develop and test an acoustic seismic source which uses hydrostatic pressure rather than explosives. The implosive device consists of a pressure case with a hole on one end. The hole is covered with a special ceramic plate prior to deployment. At depth, the plate is broken, causing an implosion, which in turn produces a low-frequency acoustic signal for use in seafloor research applications such as dealing with shallow shear velocity structures and short refraction profiles. Work to be performed involves engineering tests and at-sea trials to compare the acoustic signals from those from other types of sound sources. The proposed implosive device would be safer than explosives and would not be encumbered with regulatory restrictions.
