Abstract: A harness plug and methods of use. Example devices include an arcuate portion and a lateral portion disposed at an outer periphery of the arcuate portion. The arcuate portion is configured to engage with arcuate portion of a hole within a spacer. A method of using the harness plug includes molding a harness plug about a portion of a cable bundle and inserting the cable bundle into an arcuate portion of a hole in the spacer through a lateral portion of the first hole. The harness plug is pressed into the arcuate portion of a hole in the spacer. A streamer spacer for use with the harness plug includes a hole having a portion having an arcuate shape and a second portion lateral to and abutting the arcuate portion and extending to a periphery of an elongate body of the streamer spacer.

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: One or more first sensors may be configured to sense seismic signals and one or more second sensors may be configured to sense electromagnetic crosstalk signals. The second sensors are not responsive to the seismic signals. The data from the first and second sensors may be recorded as first data and second data, respectively. The first data may be modified based on the second data to remove the electromagnetic crosstalk noise form the seismic data.
