  • Method and apparatus for monitoring changes in underwater sediment levels
    Patent number: 5032794
    Abstract: Changes in underwater sediment level in a marine environment are monitored electronically using a probe embedded in the sediment. The probe includes an electrical current source to generate an electric field extending across the sediment interface. Voltage measurements are taken at at least three sensors on the probe whose positions are known relative to the current source. The height of the sediment interface relative to the current source can then be calculated, and logged, and changes in sediment level can be monitored. The conductivities of the sediment and seawater can also be calculated by taking additional voltage measurements.
