为了满足滩浅海高精度油气资源勘探的需要，在野外资料采集过程中，将检波器沉放到海底。

To satisfy the need of high precision oil and gas resource exploration, detectors are put on the seabed during the process of field data acquisition.

在滩浅海地震勘探中，由于海水深度和潮流的变化，在水面上按照预定位置沉放的检波器，在海底不可能放置在预定的位置。

Because of the variation of seawater depth and tide, the detector placed in the seafloor cannot be located in the designed position during seismic exploration in the paralic zone.

声波从海底之下的岩层反射回来并由检波器接收。

The sounds bounce off rock layers below the sea floor and are picked up by the phones.
