    Abstract: A solid marine seismic cable assembly (10) includes a cable (16) hydrophone housings (20), a buoyant filler (24), and an outer protective jacket (28). The cable includes a load-bearing fiber bundle (32), data-transmitting wires (36), power conductors (38), optical fibers (40), and a protective sheath (42). The data-transmitting wires (36), power conductors (38), and optical fibers (40) surround the load-bearing fiber bundle (32). The protective sheath (42) surrounds the assembly of the data-transmitting wires (36), power conductors (38), optical fibers (40), and the load-bearing fiber bundle (32). The hydrophone housings (20) affix around the cable (10) in a spaced-apart relationship. Each hydrophone housing (20) includes a hydrophone module (56), and each hydrophone module contains a hydrophone (14). The buoyant filler (24) surrounds the cable (16), and separates the hydrophone housing (20). The outer protective jacket (28) surrounds the hydrophone housing (20) and the buoyant filler (24), enclosing the cable (16) assembly.

    Abstract: A graphical user interface (GUI) and control system (102) for controlling and testing an acoustic source (14). The control system includes real-time data processing (124) of individual source near-field measured signatures and synthesis of array far-field signatures. The control system (102) determines individual source out-of-specification conditions and computes far-field signatures based on an array configuration and, when applicable, excluding failed sources. Source, array, and troubleshooting information are presented to a user in real-time over a GUI monitor (126) to allow informed decision-making regarding continued and/or modified survey operations and operational parameters.

    Abstract: Et bevegelsesfølende element med posisjonsavsøking omfatter en kasse/ramme, en magnet plassert innenfor kassen/rammen, en fjærsammenstilling med en elektrisk ledende bestanddel og en spolesammenstilling koplet til fjærsammenstillingen. Spolesammenstillingen og magneten er bevegelige med hensyn til hverandre. En kondensatorplate er plassert nær den elektrisk ledende bestanddelen med en avstand mellom kondensatorplaten og den elektrisk ledende bestanddelen som er variabel, mens magneten og spolesammenstillingen beveger seg. Ledere forbinder kondensatorplaten og den elektrisk ledende bestanddelen til en følekrets for å anslå de relative posisjoner av magneten og spolesammenstillingen.

    Abstract: A seismic source signal generator includes a mass, a primary accumulator and a . secondary accumulator, the secondary accumulator having an internal volume smaller than an internal volume of the primary accumulator. A method for generating a signal using a seismic vibrator includes operating the seismic vibrator using hydraulic fluid, damping hydraulic pressure deviations in the hydraulic fluid using a first accumulator in hydraulic communication with the hydraulic fluid, and damping pressure deviations in the hydraulic fluid using a second accumulator in hydraulic communication with the hydraulic fluid, the second accumulator having an internal volume smaller than an internal volume of the first accumulator.
