A method includes receiving electric field data regarding an electric field that is detected in an underwater environment by a plurality of electrodes mounted on a first structure, and receiving sensor data from at least one sensor mounted on the first structure. The sensor data relates to a sensed location of a second structure. The method includes determining location data including information regarding a location of the second structure relative to the first structure in the underwater environment based on the sensor data, and determining one or more characteristics of the second structure based on the electric field data and the location data.

Devices, methods, and systems for underwater surveying

Embodiments of the present invention are generally related to compensation of magnetic data, and, in particular, to a system and method for compensation of magnetic data as collected during autonomous underwater vehicle mapping surveys.

Compensation of magnetic data for autonomous underwater vehicle mapping surveys

The present invention, in various embodiments, is directed to a geophysical system and method in which a transmitter coil is oriented with its axis horizontally, and a sensor is positioned below the coil to measure an ambient electrical and/or magnetic parameter associated with a conductive medium surrounding the at least one transmitter coil.

Underwater electric field electromagnetic prospecting system

Methods for detecting gold and quantitating gold in ore samples utilizing a gold-specific protein are provided, including methods for multiple sample handling. Also provided are methods for extracting gold from mineral suspensions utilizing a magnetic mineral binding reagent and gold-specific protein, or hydrophobic reagent and gold-specific protein in conjunction with a flotation reagent.
