Techniques for surface exploration and monitoring are presented. In representative embodiments, a system is provided that cars perform multiple types of measurements of a surface. For example a single system of survey probes and one or more survey controllers can be used to offer both seismic and electrical measurements. A survey controller can be configured to automatically poll survey probes to obtain identifiers of the probes aid determine a relative order the probes. Survey probes can be configured to: (a) collect signals associated with a surface; (b) digitize the signals to form digital data; and (c) store the digital data for later transmission to the survey controller. Relative positions of survey probes can be automatically determined using a transmitting beacon or other techniques. Survey probes can automatically disconnect from a power conduit while measuring a surface property and operate using an internal source of power when disconnected, to reduce noise. The survey controller can be remotely accessible through a computer network for remote control of the survey probes.

Techniques for surface exploration and monitoring

Techniques for surface exploration and monitoring are presented. In representative embodiments, a controller can be configured to automatically poll survey probes to obtain identifiers of the probes and determine a relative order the probes. In some embodiments, survey probes can be configured to: (a) collect signals associated with a surface; (b) digitize the signals to form digital data; and (c) store the digital data for later transmission to the survey controller. In some embodiments, survey probes can be configured to: (a) inject current into the surface or (b) provide a return path therefor. Relative positions of survey probes, including those configured to introduce current into a surface as stimulus for geophysical measurements can be automatically determined. Sensor-type survey probes can automatically disconnect from a power conduit while measuring a surface property and operate using an internal source of power when disconnected, to reduce noise.

Methods and apparatuses for measuring an electrical property of the ground. The apparatus includes a graphite electrode. The graphite electrode includes a graphite body and a first and second opening. The first opening extends longitudinally throughout the graphite body and is configured to receive a multi-wire cable. The second opening is configured to secure one or more wires of the multi-wire cable to the graphite body. Using a graphite electrode, measurements of the ground can be made over a long period of time without having to clean or otherwise maintain the electrodes because the graphite material withstands operating conditions over many years without degradation.
