Abstract: A mixed rope used for oceanographic buoy mooring system, comprises mixed core rope of metal and fiber and cover rope, wherein, the mixed core rope of metal and fiber comprises metal coil spring and fiber supporting core inside the metal coil spring; the cover rope is woven of several number of twisted strand; the mass content of the mixed core rope of metal and fiber is not greater than 20% of the mass of mixed rope, the mass content of the cover rope is not less than 80% of the mass of the mixed rope. Mixed rope used for oceanographic mooring system disclosed in present embodiments has small linear density and high fracture strength, may be used as data communication channel from under-water sensor to the over-water receiver, being soft, light and easy to deploy, the mixed rope can be used as the upper part of the oceanographic buoy mooring system with prospective application.

Abstract: Disclosed are embodiments of rope designs and making and manufacturing of such ropes. In some embodiments, a rope comprises a set of first rope cores, each first rope core of the set of first rope cores comprising a first material; a set of second rope cores, each second rope core of the set of second rope cores comprising a second material, the second material being different from the first material; and a rope sheath configured to encompass the set of first rope cores and the second rope core. In some cases, the rope sheath is braided from a plurality of rope sheath strands.
