      A seismic reflection profiling system utilising a surface air gun source and a deep-towed horizontal hydrophone streamer has been developed for high resolution studies in the deep ocean. The instrument is deployed on a conventional armoured single conductor cable at depths of up to 6 km. Seismic data from the 30 m long streamer is wide-band frequency modulated up the towing cable Cited by: Marine Seismic Equipment and Acquisition Market Estimated to Reach US$ Mn and US$ 5, Mn by Transparency Market Research . @article{osti_, title = {Ocean-bottom cable use surges for seismic data acquisition}, author = {Barr, F.J.}, abstractNote = {During the last 5 years, a significant resurgence has occurred in the use of ocean-bottom cable (OBC) methods for acquiring seismic data in water as deep as m. There are a number of reasons for this increased activity.

Abstract: A reliable high density and precise streamer cable digitizer for marine seismic exploration system is introduced. In this digitizer, there are total 16 data acquisition channels each of which can be connected to hydrophones directly. Analog signals are converted into digital data by bit high precise ΔΣ ACDs which is controlled by FPGA in real time.

Marine environmental research often deploys array hydrophones to track underwater marine life and their behavioral patterns. Underwater surveillance can also be managed using array hydrophones. For example, the US Navy’s sound surveillance system consisting of a series of hydrophone arrays were placed in the Atlantic Ocean in the s to Author: Azosensors.

Hydrophone stations use underwater microphones (hydrophones) attached to cables anchored to the seabed 50– km offshore and connected by cable to a land facility for data transmission. They are extremely sensitive and pick up acoustic waves from underwater events, including explosions, vast distances away.

Hydrophones & streamers. To provide a complete seismic system, SIG has developped its own hydrophone elements to mount into the streamers, and make high resolution arrays to work with sparker and boomer systems. The SIG 16 hydrophone streamers have small diameters of 31 mm, with a density of on standard.

With m hydrophone group intervals 16 channel streamer sections are easy to manage and store whilst also being a cost effective. The diameter of the streamer remains mm allowing the system to be deployed by hand off small vessels with a small tail buoy for tracking the streamers location with GNSS.

Embedding all necessary inputs and outputs, it accurately digitizes single to multi-channel seismic signals. Thanks to a single Ethernet output, acquired data is logged on any laptop or workstation running DELPH Seismic Acquisition software.

This is a new standard for high-resolution seismic. In order to perform a 3-D marine seismic acquisition survey, an array of marine seismic streamers, each typically several thousand meters long and containing a large number of hydrophones and associated electronic equipment distributed along its length, is towed at about 5 knots behind a seismic survey by: Marine Seismic Detector.

BII series marine seismic detectors are pressure geophones whose output voltages are in response to the pressure outside the units at sea (fresh water, or marsh and land-water transition-zones), and the translational acceleration of the unit is cancelled.

The SEG Y Data Exchange Format (rev 0) was published inand has achieved widespread usage. However, sincethe nature of seismic data acquisition, processing, and seismic hardware has changed significantly. SEG Y Revision 1 addresses these changes and updates the format for modern usage.

show that processing techniques can realize broadband marine seismic results from conven-tional streamer acquisition data without the need for the emerging built-for-purpose broad-band streamer technology.

T he vast majority of marine seismic data is acquired with conventional towed streamer cables which are equipped only with hydrophones and. This paper presents an overview of a standard ocean bottom cable (OBC) seismic technology, a marine seismic data acquisition system that has now been introduced into Nigeria by one of the major multinational companies.

This technology is compared with the normal marine seismic data acquisition system using a towed streamer.

This is to. Marine receivers are composed of piezoelectric hydrophones, which respond to changes in water pressure. In marine acquisition, seismic vessels sail along predetermined patterns of parallel circuits.

The length of straight segments is calculated from fold plots, and must include additional length run in and run out to allow the cable to. Close mobile search navigation.

Article navigation. Vol Number 5. A seismic streamer and a method for positioning a group of hydrophones in a seismic streamer. The hydrophones in a group are spaced irregularly along the length of the streamer to reduce the influence of bulge-wave noise and flow noise on the hydrophone group response.

The irregular spacing may be produced as pseudorandom deviations of the actual positions of the hydrophones Cited by: Hydrophone Array/Streamer Element Low Cost Array Element: BII Series Marine Seismic Hydrophone Acceleration Cancellation: BII Series Low Flow Noise Hydrophone Streamlined Body: Hemispherical Dome & Cone: BII Series Miniature Probe Hydrophone Probe: ΦD to mm 1Hz to 3MHz: BII Series Directional Hydrophone Fan-shaped Beam.

Traditional marine seismic surveys are conducted using specially-equipped vessels that tow one or more cables containing a series of hydrophones at constant intervals (see diagram). The cables are known as streamers, with 2D surveys using only 1 streamer and 3D surveys employing up to 12 or more (though 6 or 8 is more common).

A land streamer is an array of geophones designed to be towed along the ground. The name originates from marine streamers: arrays of hydrophones towed behind boats for marine seismic surveys. Land geophysicists have long envied the high productivity achieved in marine surveys.

Now it appears that highly-productive reflection, refraction. Our streamers are specially designed to meet hi-res seismic requirements.

The high quality materials used ensure high sensitivity and the best performance in terms of bandwidth and S/N ratio for both single and multi channel acquisition.

Standards for specifying hydrophone streamer-cable characteristic ICS E A surface marine cable, usually a buoyant assembly of electrical wires that connects hydrophones and relays seismic data to the recording seismic vessel.

Multistreamer vessels tow more than one streamer cable to increase the amount of data acquired in one pass. INTRODUCTION received by the pressure-sensitive hydrophones in the streamer cables. Post-processed signals provide The main objective of marine geophysical images of the stratigraphy and are interpreted by exploration is to detect offshore hydrocarbon geophysicists to determine whether additional, more resources by determining the geological Cited by: 6.

GPS for Marine Seismic Surveying. Marine seismic surveying is similar in principle to land seismic surveying. That is, a low-frequency acoustic energy is sent down into the subsurface rock layers and is reflected back to the surface to reveal information about the composition of subsurface rocks (Figure ).
