Abstract: Described is an improved optical fiber cable specially adapted for seismic sensing. Compared with standard optical fiber cable, this improved optical fiber cable is reduced in size, lighter, and more flexible. These characteristics make the optical fiber cable more robust for reusable applications. Due to modifications in the design of the optical fibers, the size and weight of the seismic sensing cable may be substantially reduced. That allows longer lengths of seismic sensing cable, and more seismic sensor boxes, to be reeled on a given sized reel, and makes deployment of the seismic sensing cable faster, easier, and less expensive. A preferred cable design for reaching these objectives comprises multiple optical fibers, of a design just described, encased in a dual-layer optical fiber buffer encasement of acrylate resin.

Abstract: Sensors used in mapping strata beneath a marine body and/or structures on a marine body floor are described, such as in a flexible buoyancy adjustable towed array. A first sensor is a traditional acoustic sensor or a novel acoustic sensor using a piezoelectric sensor mounted with a thin film separation layer of flexible microspheres on a rigid substrate. Additional non-acoustic sensors are optionally mounted on the rigid substrate for generation of output used to reduce noise observed by the acoustic sensors. Combinations of acoustic, non-acoustic, and motion sensors co- located in rigid streamer housing sections are provided, which reduce noise associated with different sensor locations and/or localized turbulence.

Abstract: Some embodiments of the disclosed invention include a method for acquiring marine seismic data using solid streamers in a curved pattern. Streamers can be towed in a curved pattern within a body of water. While being towed in the curved patter the source may be fired and response data can be collected by the streamers as they are towed through the water in the curved/circular pattern. These streamers can be solid streamers and can be filled with a gel like substance. Moreover, the streamers can be placed at various known depths within the body of water.

Abstract: A technique includes receiving data indicative of non-uniformly spaced samples of particle motion wavefield acquired by particle motion sensors while in tow. The samples are spaced apart by an average spacing interval, which is not small enough to prevent vibration noise from being aliased into a signal cone for a first signal formed from samples of the particle motion wavefield having a uniform spacing at the average spacing interval. The technique includes processing the data to generate a second signal that is indicative of the particle motion wavefield and does not have aliased vibration noise in the signal cone.
