摘要：Various sources of the electric field in the marine environment are analysed, which can be divided into artificial and natural sources according to causes, DC and AC sources according to the frequency. In order to better grasp electric fields in marine environment, a data acquiring system of the electric field is introduced based on msp430. The system has characteristics of low noise, low power and high resolution etc. Then ocean tests are carried out and the electric fields are acquired in offshore port and open sea respectively successfully. It is found that the environmental electric fields of offshore port are very different from that of pelagic environment, and the amplitude and frequency of the electric fields vary greatly with the sea conditions.
