SuperSting™ Marine Resistivity

Product Documents

The SuperSting Marine Resistivity is an add-on module to the SuperSting Wi-Fi, our multi-channel electrical imaging system. It allows for the collection of streaming marine (towed cable) data. Items in this module allow resistivity/IP hydrographic surveys with continuously recording 2D and 2.5D data which contain positional data from a GPS receiver, along with the depth profile measured with 200 Khz echo sounder. Other NMEA position and depth data streams (industry standard) can be synchronized as well.

Benefits

The fully automated SuperSting Marine module system is ready to use with minimal changes to the land mode. Compared to land system—the SuperSting R8 Wi-Fi—the Marine Resistivity Module is able to collect extraordinarily large amounts of data in a working day. To use the marine module, you simply connect the accessories and then tow the sensor cable behind your boat at ~3-8 km/h or 2-5 knots. The module gathers continuous 2D or 2.5D images; in an eight-hour day, it is possible to gather over 40 linear kilometers of data!

Common Applications

This data can be used for myriad reasons, including:

  • Determining sub-bottom geology for dredging purposes

  • Monitoring leakage in a dam

  • Mapping fresh and saltwater interfaces near shorelines
    or offshore

  • Characterizing the sub-bottom of estuaries

  • Measuring water column salinity variations

  • Mineral exploration (usually placer deposits)

  • Locating freshwater springs at sea (submarine
    groundwater discharge)

  • Distinguishing between hard rock, sand, gravel, silt,
    and clay

SuperSting Marine Resistivity Use Case: Dredging

A canal authority is doing an expansion project and needs to dredge part of the channel, and they want a better idea of how much it will cost to excavate the unwanted sediment and rock. The canal authority knows dredging companies’ bids are often very broad, as the dredging company doesn’t always know exactly what they’re getting into with the project until the excavation begins. With the SuperSting Marine Resistivity, the canal authority is able to provide more detailed information about where the soft sediment is and where the hard rock is so the dredging company can provide a more specific and low risk bid and on the bottom line save costs to the canal authority.

Product Features

  • Current is injected every three seconds and voltage is measured, representing eight depth levels are read for each current injection.

  • Depth of penetration depends on the length of the graphite electrodes spacing (U.S. Patent 6,674,286) and the array type used. Typically you will image down to approximately 20% of the electrode-spread length using the Dipole-Dipole array. For example, a 100-meter-long electrode cable will image down to about 20 meters.

  • Resolution is proportional to the electrode spacing by 50%. (To increase the resolution, you have to shorten the electrode spacing. For example, if there is an electrode spacing of 10 meters, the best resolution is 5 meters.)

  • Real-time data plotting—which allows you to see the data stream in real time as the boat advances—is made easy with any Android device. You are in control of the survey and able to recognize the quality of the data and adjust for unaccounted field variables on the spot.

  • Remote control of the SuperSting Marine is simple when you use the included Android SuperSting Manager App (available in the Google Play Store).

 

SuperSting Manager (SSM) App Features (available in the Google Play Store)

  • Real-time data visualization.

  • Upload command files and download
    data files.

  • File sharing via wireless connection.

  • GPS streams wirelessly to the SuperSting

  • Redundant GPS positioning. (Should the
    GPS position be lost by the GPS/depth
    sensing unit, the SSM will record the
    Android device GPS position momentarily)

  • Overlay the depth and temperature data
    over the collected data in real time.

  • Create command files.

  • Edit any text files (including the data and
    command files).

  • Monitor instrument battery levels

  • Remote control of the SuperSting over a
    persistent Wi-Fi connection (no internet required)
