A system includes a body portion having rear portion having a fluid intake
port and a nose portion having a fluid discharge port. The body portion
contains an omni-directional vibratory device, a pump, a fluid conduit
that is coupled to the pump and the fluid discharge port, and a power
source that is electrically connected to the vibratory device and the
pump. The body portion may also contain control circuitry and two end
caps rigidly fixed therein, wherein the fluid conduit passes through each
end cap. The vibratory device and the pump may be activated by a sensor
such as a hydrostatic pressure sensor, an accelerometer, or an altimeter.
The body portion may also contain communications circuitry that remotely
controls the vibratory device and the pump. The body portion is
configured to house a payload such as a sensor system, a battery pack, or
a ballast for anchoring.
