Abstract: At least some of the exemplary embodiments are a method. The method includes obtaining, at an underwater imaging device, a stream of images of geophysical surveying equipment, wherein the geophysical surveying equipment includes a target pattern having a calibrated image size. The geophysical surveying equipment is tracked using the image stream and the target pattern. The method further includes capturing from the image stream, a single image of the images of the geophysical surveying equipment, wherein the single image comprises an image of the target pattern having an apparent size. Based on the calibrated image size and the apparent size, a distance between the underwater imaging device and the geophysical surveying equipment is determined.

Abstract: Valves. At least some of the example valves include: a valve body; a valve housing; and a piston that defines a proximal end and a distal end, the piston disposed in a piston bore of the valve housing. The valve defines a closed orientation by a first rotational orientation of the valve housing relative to the valve body, and the valve defines an open orientation by a second rotational orientation of the valve housing distinct from the first rotational orientation.

Abstract: Embodiments relate generally to marine geophysical surveying and, more particularly, embodiments relate to methods for acquiring geophysical data by dynamically manipulating survey spread in response a change in location of a target. A method may comprise actuating an energy source in a body of water, wherein a target for a marine geophysical survey system is located beneath a bottom of the body of water. The method may further comprise detecting energy generated by the energy source. The method may further comprise manipulating a position of a survey spread in response to a change in distribution of the target beneath the bottom of the body of water.

Abstract: Techniques are disclosed relating to acoustically interfacing marine survey devices. In one embodiment, a system includes survey equipment, first and second acoustic transducers, and a first device. In this embodiment, the first acoustic transducer is coupled to the survey equipment and configured to perform at least one of receiving survey information and sending control information. In this embodiment, the first device is not directly coupled to the survey equipment. In this embodiment, the second acoustic transducer is coupled to the first device and configured to perform at least one of sending survey information and receiving control information. In one embodiment, the first acoustic transducer is included in or coupled to a streamer cable.
