In recent months Seismic-Mechatronics have been working on increases the output force of their Lightning electromagnetic seismic vibrating source through synchronising multiple units to within 8us.

The P & S wave source is the most powerful vibrating source for it size available commercially, and can be run from a 48VDC or mains supply. The Lighting is proving itself to be a power yet easy to use seismic vibrator source for near surface site investigation and structural dynamics testing.

Further information can be found on the Lightning webpage or feel free to email sales@geomatrix.co.uk.

Not only does the IWA increase the range of our best-in-class winches, but it also sets new standards for ease of use, safety, power, compactness, and durability.

Featuring an intuitive touchscreen interface, all winch settings and system diagnostics are shown and controlled through the weatherproof membrane touchscreen. The interface user-friendly, and the digital control and programming of the IWA provides the operator with better control and unique safety features, including the following settings:

• Maximum speed control of the winchIWA winch touch-screen display
• Wireline acceleration safeguard
• Depth alarms and automatic winch braking
• Adjustable tension shut-off limits
• Level-wind calibration
• System diagnostics
• PC interface to permit remote support and control

On top of its intelligence, the IWA is also brawny. This winch has a 6 HP servo motor that can operate at speeds over 55 meters/minute (180 feet/min) and lift the heaviest tool stack with ease. Being the strongest winch in its class doesn’t mean the IWA is bulky and cumbersome. The IWA has a very small footprint. The completely redesigned level-wind assembly keeps the winch footprint at just 1.1 x 0.9 x 0.8 meters (45 x 37 x 32 inches), only slightly larger than our 2 HP WFA winch.

Geomatrix Earth Science are delighted to anouse the delivery of a 32 channel GeoEel™ Solid Digital Streamer, a state-of-the-art marine seismograph, the British Antarctic Survey (BAS) and the Natural Environment Research Council (NERC) to outfit the newly-built RRS Sir David Attenborough.

The RRS Sir David Attenborough is a Polar-class 4 research vessel intended for marine and oceanographic research in the polar regions of the world. The BAS and NERC intends to fully equip the Sir David Attenborough with the most advanced research equipment available, from remote-controlled submersibles to advanced weather monitoring equipment. The GeoEel Streamer is one of the most advanced digital marine seismographs available today, and will be a great addition to the other research capabilities of the Sir David Attenborough.

With the GeoEel, the British Antarctic Survey will perform seismic reflection profiling, which enables imaging of geological structure and strata beneath the seafloor, on multi-disciplinary cruises. Such data provide immense added value to many geoscientific and paleoenvironmental studies and can also be used in informing the interpretation of other data sets such as swath bathymetry, sub-bottom profiles and sediment cores.

Seismic reflection profiling on multidisciplinary cruises, which enables imaging of geological structure and configurations of sedimentary strata to sub-seafloor depths of >1 km. Such data provide immense added value to many geoscientific and palaeoenvironmental studies, and are of great help in informing the interpretation of other datasets, such as swath bathymetry, acoustic sub-bottom profiles and sediment cores.

At SAGEEP 2018 Geonics announced the release of a new range of metal detectors designed for UXO detection in channelling environments. The new Flex range of time domain EM sensors is tailored towards improving productivity through the deployment of multi receiver coil arrays. The Flex systems are targeted toward different survey scales;

The EM61-BLU26 consists of 4 0.5x0.5m receiver coils, in a linear array, and a flexible 2.25x0.45m transmitter coil. The system is modular and can be configured with 2 receiver coils and a 1.13x0.45m transmitter coil in constrained environments. The adoption of smaller receiver coils increases spatial resolution enhancing the detection of small shallow objects; whilst maintaining a large transmitter coil area ensures sufficient magnetic moment potential for resolving deeper objects.

The EM61-LX2 is a two channel variant supplied with the two 1mx0.5m receiver coils. Both systems measure and record the decaying magnetic field on each receiver coil at two time gates. A third calculated value is also recorded for each channel, which has been subjected to a proprietary algorithm which removes the influence of magnetic soils and rock materials.

The EM63-Flex is specifically designed for efficient large open area surveying. The system consists of four 1mx0.5m receiver coils and one transmitter coil which encircles the receiver coils. Deploying an array like this is nothing new; customers have been deploying 3 time synchronised EM61MK2 for large area surveys for many years. However the EM63-Flex offers 26 time gates per channel and is capable of recording 15 full records per second offering much greater fidelity than was previously achievable.
