Abstract: Systems and methods for geophysical exploration of underwater environments are provided. In some embodiments, a geophysical measurement system includes at least one cable having a cable distributed array of electrodes. In some embodiments, the geophysical measurement system further includes at least first and second unmanned vehicles submersible below water for coupling at respective points along the cable so as to maneuver a segment of the cable that includes at least some of the cable distributed array of electrodes through a series of positions and orientations relative to subsurface geologic features below the water, where respective ones of the electrodes along the maneuvered segment participate as transmitters or receivers in electrical resistivity imaging of the subsurface geologic features from at least first and second maneuvered-to positions or orientations that differ from one another.

Abstract: A reflective cable system for a geophysical survey system includes a reflective cable that includes a conductive wire surrounded by an electrically insulating sheath and an exterior surface. The reflective cable includes reflective material that is on or visible through the exterior surface and that is configured to reflect a complete spectrum of light provided by a light source back to the light source. The reflective cable system also includes a connector electrically coupled to at least one end of the reflective cable and configured to couple to a geophysical survey system. The reflective cable may be used to locate the reflective cable in a physical environment and used to determine a position of the reflective cable using lidar or photogrammetry for generating geophysical survey models.

Abstract: An augmented reality (AR) object positioning system receives a target coordinate for a location of interest within a physical environment. The AR object positioning system then determines an AR device coordinate of an AR device within the physical environment and orientation information of the AR device at the AR device coordinate. The AR object positioning system calculates a plurality of image frame coordinates of an image frame based on the AR device coordinate and the orientation information when the image frame was captured. The AR object positioning system, in response to an image frame coordinate of the plurality of image frame coordinates corresponding with the target coordinate, renders on a display of the AR device, first annotation content relative to the image frame coordinate according to rendering instructions for the first annotation content.

Abstract: 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.
