ABSTRACT:
An air-bladder free hydrophone streamer for use in an aqueous environment and a method of manufacture thereof. The hydrophone streamer includes: (1) data acquisition equipment including data bus interconnecting a plurality of hydrophones, the data acquisition equipment having a specific gravity greater than that of an environmental fluid constituting the aqueous environment, (2) a jacket surrounding the data acquisition equipment, the jacket forming a void about the data acquisition equipment, the jacket having a specific gravity less than that of the environmental fluid and (3) a water-based fill fluid occupying the void, the jacket providing buoyancy for the data acquisition equipment to allow the hydrophone streamer to assume a near-neutral buoyancy with respect to the environmental fluid.
