1. A system for measuring the resistivity of sea-bed, ice, or geologic formations, the system comprising:

  • at least one stationary long-range transmitter formed by a system of grounded electric bipoles of more than three kilometers in length or formed by a loop of wire with the radius of more than three kilometers,at least one receiver that is remotely located form the at least one stationary long-range transmitter; and

    a computing system, the computing system comprising;

    a processor; and

    one or more physical non-transitory computer readable medium having computer executable instructions stored thereon that when executed by the processor, cause the computing system to perform the following;

    generate an electromagnetic field using the at least one stationary long-range wherein the frequency of the electromagnetic field is between or including the ULF/ELF range;

    measure at least one component of the electromagnetic field using the at least one receiver;

    determine a conductivity distribution based on the at least one measured component; and

    correlate the determined conductivity distribution with geological formations or hydrocarbon deposits.
