1. A marine geophysical survey system comprising:
a streamer; and
a wax application system operable to receive the streamer on deployment and apply a wax coating to the streamer as the streamer is being deployed from a survey vessel into a body of water, wherein the wax application system comprises one or more wheel applicators positionable around a circumference of the streamer, wherein the one or more wheel applicators are formed from a wax in a solid state.
