海底大地电磁探测要解决的首要问题是海底信号采集。
The main problem of Marine magnetotelluric prospecting is the acquisition of Marine sea bottom signal.
近期的海洋试验表明，中国的海底大地电磁探测技术已实现了实用化，可为海洋勘查提供高技术支撑。
Recent marine experiments indicate that the seafloor magnetotelluric prospecting in China have achieved utility and can offer high technology support in marine prospecting.
相对于陆上同类测量而言，海底大地电磁探测成本高，作业难度大，且不易实施数据采集的重复观测。
Compared with continental operation, there are higher risk and expenses in detecting and more difficult in acquisition repeatedly on the marine magnetotellurics.
