Abstract

Embodiments described herein provide an EM source cable assembly with a buoyant member having first and second ends, and a longitudinal axis connecting the first end to the second end, and a plurality of indentations disposed along a surface of the buoyant member between the first end and the second end, wherein the indentations are operable to receive corresponding cables. The indentations extend along the longitudinal axis, and may be arranged helically about the longitudinal axis. The buoyant member may have a low density core material and a dense outer material, each of which may be a polymeric material. The low density material may be a foam, and the buoyant member may be formed by coextruding the low density material and the dense outer material.
