Abstract: A section of a streamer for acoustic marine data collection, the section having a carrier for accommodating seismic sensors, wherein the carrier includes, a single body, a first particle motion sensor located on the single body, and a second particle motion sensor being located on the single body, with a 90° angular offset, about a longitudinal axis of the carrier, relative to the first particle motion sensor; and a tilt sensor coupled to the carrier and having a known direction relative to the first and second particle motion sensors so that the tilt sensor determines an angle of tilt of the carrier about a vertical. The first and second particle motion sensors measure a motion related parameter and not a pressure.

Abstract: A seismic streamer includes a sensor comprises an axially oriented body including a plurality of axially oriented channels arranged in opposing pairs; a plurality of hydrophones arranged in opposing pairs in the channels; a pair of orthogonally oriented acoustic particle motion sensors; and a tilt sensor adjacent or associated with the particle motion sensors. The streamer has a plurality of hydrophones, as previously described, aligned with a plurality of accelerometers which detect movement of the streamer in the horizontal and vertical directions, all coupled with a tilt sensor, so that the marine seismic system can detect whether a detected seismic signal is a reflection from a geologic structure beneath the streamer or a downward traveling reflection from the air/seawater interface.
