| 摘要： | Along tripod legs of standard coastal cable to be anchored 19,000 feet deep were 30 hydrophones, 12 temperature sensors , several engineering sensors , and 3400 10 and 16 inch glass buoyancy elements . Electronic packages with the sensors were to multiplex signals along the cable , avoiding the weight and handling problems of separate conductors . At the apex a subsurface buoy to stay within diver depth contained signal-conditioning and control electronics and three radioactive thermoelectric generators . A surface buoy on a rubber pendant was to transmit VHY and HF telemetry to a ship and to shore . Implantment was attempted unsuccessfully from a stable . maneuverable , offshore-oil-rig supply boat. Powered cable tensioning winches streamed each leg outward from the surface-moored subsurface buoy and then lowered the anchor on an expendable crown line. Anchoring the third leg would also have pulled down the subsurface buoy. The primary cause of failure was the firing of an anchor release during implantment. Subsequent damage to the cables resulted from storm conditions which arose . Future moors require more work on light strong cable , reliable electrical terminations bondable to polyethylene dielectric cable material, and light hydrophone/electronic assemblies which are isolated from vibration of the cable. |
