    General Conditions of Use:

    Geophysics field equipment is available for use by qualified staff and students members of the London Colleges Geophysics Field Equipment Pool.

    List of Equipment

    Ground Penetrating Radar(GPR)

    Sensors and Software pulse EKKO PE-100A GPR (1000V) system with 100 and 200MHz antennae.

    Introduction

    Ground penetrating radar (GPR) has recently become the must-do geophysical survey technique because of its ease of use and unparalleled ability to image the near sub-surface in detail. In archaeology it is used to locate burial grounds and determine buried structures (most famously, the Tomb of Christ beneath the Church of the Holy Sepulchre). In geology it is used to map sedimentary structures (e.g. ancient lake beds, braided river channels). In geography it is used to characterize sand dunes, glacial moraines and glacial ice stratigraphy. In civil engineering it is used for site investigation, to determine soil properties, log deterioration in structures (such as bridges) and locate utilities, buried pipes and cables. In environmental science it is used to locate buried waste drums, groundwater, contaminant leaks or plumes. 

    Details of equipment

    Purchased: 2002 Cost: £30k Condition: Excellent

    Funded by: UCL Supplementary Teaching Equipment Grant (50%); Birkbeck College, School of Earth Sciences (50%).

    Notes: The equipment is not weather-proof so plastic bags must be taped around transmitter & receiver, and the laptop needs to be kept dry. Car battery is needed for operation.

    GPR equipment is also available from Kings College. Contact Mark Mulligan for further details.

    Seismic

    Geode 12-channel in-field Seismograph

    Seismic surveying is one of the most effective ways to explore rock and subsoil. It is ideal for finding groundwater, oil and useful minerals. Common applications include:

    • Depth to Bedrock 
    • Site Investigation 
    • Geotechnical Properties 
    • Groundwater Exploration 
    • Hydrocarbon and Coal Exploration

    The new Geode seismic recorder is the next generation of seismic recording systems. It can be used for refraction or reflection, downhole or VSP - even tomography surveys.

    Details of equipment: GEODE 12-CHANNEL IN-FIELD SEISMOGRAPH

    With built-in high-speed connection to interface with PC-compatible. Suitable for seismic reflection, refraction, downhole, cross-hole, surface wave, and tomography surveys, and vibration and earthquake monitoring.High-speed over sampling combined with digital signal processing give a 24-bit result using Crystal Semiconductor sigma-delta A/Ds. Extra wide bandwidth (1.75 Hz to 20 kHz) permits high- resolution user-selectable sampling intervals from 20 microseconds to 16 milliseconds. Data acquired and summed in 32-bit stacker then transferred back to host computer for storage in SEG2 format on hard drive. Built-in pretrigger and 16,000 sample memory for each channel. Includes software selectable low-cut, high-cut, or notch real-time digital display filters for noise reduction.

    Gravimeter

    Sodin 420-T Gravimeter; UCL Earth Sciences

    Gravity surveying involves the measurement of the Earth's gravitational field, which is a function of:

    • Distance from the centre of the Earth 
    • Centrifugal acceleration due to the Earth's rotation 
    • The distribution of the mass, which is controlled by topography and changes in the density of rocks 

    After making the necessary corrections to the recorded data, the final gravity anomaly map represents variation in the mass distribution in the Earth. The method is being increasingly used in the location of cavities, voids, and abandoned mine shafts. [Geomatrix Earth Sciences Ltd.]

    Details of equipment: Sodin 420-TGravimeter with thermostatic control

    Purchased: 1973 Cost: £20k Condition: Fair

    Funded by: UCL Department of Earth Sciences

    Notes: The Sodin gravimeter is difficult to operate and very difficult to transport as it cannot be clamped (sharp sideways accelerations and tilting past 45o can cause severe damage). Due to the fragile nature of this equipment, it is not available for hire.

    Magnetometers

    In a magnetic survey variations in the Earth's magnetic field are measured. The method has the advantage of being one of the easiest and cheapest geophysical techniques to carry out, since large areas can be covered quickly at a low cost and few corrections to the field data are required.

    Magnetic surveying has been widely used for many years in the mineral and oil exploration industries but with recent advances in the speed of operation and resolution of portable systems can be used for industrial and environmental applications such as the detection of abandoned mine shafts and adits, detection of man-made targets such as brick lined shafts or the remains of ancient dwellings. Additionally the technique can be used for the location of underground storage tanks and buried steel drums, as well as high resolution archaeological surveys. [Geomatrix Earth Sciences Ltd.]
