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: 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.
