When the fixed marine electromagnetic acquisition equipment is distributed in the ocean, the fixed marine electromagnetic acquisition equipment is thrown into the sea, slowly sinks to the sea bottom under the action of the gravity of the counterweight, and starts to record magnetic field and electric field data.
