  • Seabed Positioning System

    GeoTag - Sercel Group

    GeoTag is the new acoustic positioning system from Sercel designed to work with any ocean bottom or transition zone seismic equipment down to 500 meters deep. GeoTag is the smallest acoustic transponder on the market, allowing flexible and cost effective operations due to its ability to be stored on a reel and deployed by mechanical squirter.

  • Multi-Cluster Sources

    Teledyne Marine Bolt

    Our complete line of sources can be configured in a Tri-Source configuration. Clustered sources are a vital part of effective seismic exploration. The destructive effects of the air blast associated with a discharging air source are made worse by clustering. In order to maintain the separation between air sources within a cluster, it is necessary to mechanically constrain the sources with rigid bars.

  • Electrodynamic Velocity Pickup

    IMV Corporation

    The principle of Reciprocal Pendulum type Pickup is to induce voltage by reciprocal motion of the seismic mass with a coil in the magnetic field being suspended by a diaphragm or coil spring.. Because of its High Sensitivity and Advanced Linearity, it is suitable for detection of malfunction or deterioration of rotational machineries. Due to its structure, mounting should be done carefully for its direction or angle.

  • Sub-bottom Profiling Module for Gavia AUV

    Teledyne Marine Gavia ehf.

    ​The Gavia Sub-bottom Profilng Module is derived from field proven Chirp III technology from Teledyne Benthos, pioneers in Chirp Technology. The Chirp Sonar uses digitally produced 14kHz-21kHz acoustic transmission and matched-filter processing to achieve both high resolution and good penetration in soft sediments. the Gavia AUV is an ideal platform for shallow seismic geotechnical data collection: the SBP is in a very low noise, low dynamic environment and the AUV can keep the sonar at a fixed height above the seabed, optimised for seismic data collection, with none of the issues seen on boat-mount or towed systems such as surface and vessel noise, heave, swell and cable snatch, and tow position uncertainty. As the AUV can approach close to the seabed in up to 1000m of water, the ping update rate can be maintained whatever the water depth (up to 15pps) and the sonar footprint can be kept small, allowing ping stacking for noise reduction and also giving enhanced spatial resolution compared with boat-mounted systems. The high frequency seismic system gives very high resolution layer separation (~0.3ms FWHM) and centimetric detection of changes in burial depth. SEG-Y data is recorded on the AUV, containing both correlated and uncorrelated data, along with the transducer depth in the SEG-Y trace headers. Synchronisation with the AUV master clock is via PPS for accurate navigation and motion correction.

  • Automation

    Signal Filtration - ZETLAB Company

    Signal Filtration is used for filtering signals coming to the input channels of spectrum analyzers, strain-gauge stations, and seismic stations, for further processing by ZETLAB programs. Signal Filtration can also be used for processing virtual channels created by such programs as Vibration Meter, Strain-Gauge Sensor, etc. Signal Filtration operates with signals both in real time and with reproduced of recorded signals.

  • Rugged Cabinet

    M1 Series - ELMA Electronic, Inc.

    Optima's M1 rugged cabinets are ready for reliable service in demanding environments. Defense, Transportation and Seismic Ready Cabinets have been lab and field tested to insure that mission critical equipment remains up and running during harsh deployment events. M1 cabinets are AREMA and CENELEC compliant tested and meet a variety of comparable defense and telecom related standards.

  • Active Vibration Isolation

    Integrated Dynamics Engineering

    This includes Passive and Active vibration isolation modules. Our vast number of advanced solutions – from compact Passive LC series to the TCN Active series expanding to the cutting edge most advanced in vacuum NGI series – provide options for every difficult application issue that exists today. Since seismic vibrations tend to be random, all frequencies need to be addressed.

  • High Sensitivity Accelerometers

    Metra Mess- und Frequenztechnik in Radebeul e.K.

    The piezoelectric accelerometers on this page are intended for the measurement of lowest vibrations. Typical fields of application include the monitoring of buildings, dams, bridges, oil platforms and pipelines. These sensors are often called seismic accelerometers because they are used to monitor construction activity, volcanoes and earthquakes. Their high sensitivity is achieved -unlike other high sensitivity accelerometers- by the sensing element itself and not by internal amplification. From this results highest resolution and lowest noise.

  • Model Estimation And Migration

  • Loop-Powered Transmitters and Drivers

    4-20mA - Riverhawk Company

    Loop-Powered Transmitters convert the output from proximity probes, seismic sensors, into a 4-20mA DC current, which is proportional to the input being measured. The transmitter converts the displacement or vibration signal to DC voltage and/or current for a DCS or PLC system. They control a 4-20mA current loop for a specified vibration range (ex. 0-5 mils peak-to-peak). The transmitters have a two-wire hook-up, powered solely by the loop current and have a power supply range of 15 to 36 volts.

  • Slip Table Assembly

    CSTA Series - Unholtz-Dickie Corporation

    Unholtz-Dickie introduced the Combined Slip Table Assembly (CSTA) in the late 1960''s to meet the demand for positive mechanical alignment between the shaker and its companion horizontal slip table. The challenge was to achieve this positive, permanent alignment feature without requiring an expensive seismic mass in the vibration lab floor. The original CSTA design has been continuously improved over the years and has now become the industry standard for permanently aligned, integral reaction mass slip tables.
