AeroMAG® UAMS
At Spectrum, we are always driving to deliver innovative geophysical survey solutions to our clients. Since 2018, we have been testing, developing and evolving our unmanned aerial magnetometer capability to support our proven nearshore marine UXO survey capability.
The year 2023 marks the introduction of the latest AeroMAG® UAMS; capable of detecting UXO in both land and marine environments, it adds greater capability to our existing geophysical survey services.
Offering a 2.6 metre wide high sensitivity and lightweight configuration with nominal survey speeds in excess of 5 m/s, the result is a more efficient survey over a longer flight time, providing increased ability to detect objects at greater range, or over deeper water.
Our track record of delivering efficient aerial magnetometer surveys over large challenging areas compared to conventional methods is resulting in faster surveys and happier clients.
Please feel free to get in touch if you think it can help reduce risk on your next project on land or over shallow water.

AeroMAG® Unmanned Aerial Magnetometer (UAMS)
A sneak peek of some data collected with our AeroMAG® Unmanned Aerial Magnetometer (UAMS) system over two test objects.
This residual total field example shows the results from only a single magnetometer flown at an altitude of 8 metres above ground @ 5 m/s survey speed and a 6 metre sensor spacing.
The data shows the ability for the system to detect potential UXO at considerable distances, enabling the platform to fly higher, or the water to be deeper.

New Drone Kit
Spectrum have invested in two of the newly released DJI M350 RTK systems to support our intertidal and land-based photogrammetry and AeroMAG® surveying capabilities.
The kit is already in the field collecting cable landing data using nadir and oblique photogrammetry techniques to ensure full coverage of the cliff line.

Kentish Flats and Thanet offshore wind farms
We've won a contract with Vattenfall!
Mobilising Spectrum 3 from Ramsgate, we'll be surveying both the Kentish Flats and Thanet offshore wind farms:
- Thanet will have a multibeam and side scan sonar survey
- Kentish Flats will have a multibeam and backscatter survey
Throughout the campaign, we will acquire high resolution and high-quality bathymetry, backscatter, and side scan sonar data to allow for the ongoing monitoring of the seabed conditions. This includes seabed mobility, scour and cable free span, and exposures at both sites, covering all Wind Turbine Generator (WTG) locations, Inter-Array Cables (IAC) routes, and the Export Cable Route (ECR) at Kentish Flats.
Spectrum 3 is a Bureau Veritas Classed MCA Category 2 coded workboat and has been purposefully adapted to operate as a dual–purpose survey/crew transfer vessel, combining fast transit speed with a stable survey platform.
We can't wait to get started!

Oakhaven HospiceSpectrum recently donated £500 to Oakhaven Hospice , a very worthy cause.
The funds were raised through staff exercise efforts, where for every 10 km cycled, and every 5 km ran or walked, £1 would be donated. Over 5,500 km were covered in 2020 by the Spectrum team. We will continue to support Oakhaven Hospice in 2021. 03/12/2020Intertidal Magnetometer Surveys
The Spectrum team have recently completed an intertidal magnetometer survey to identify existing infrastructure, including a buried pipeline. The survey involved using both marine and aerial magnetometer methods and marked the inaugural commercial flight of our new AeroMag™ system. This system utilises RTK positioning with the latest MFAM™ caesium magnetometer technology from Geometrics Inc. , sampling data at 1000 Hz, making magnetometer data acquisition over these shallow intertidal waters areas faster, more accurate and easily accessible. +Read More -Read Less 28/07/2020London Wreck Survey
Spectrum recently carried out a high resolution multibeam survey of the London wreck site on behalf of MSDS Marine. Located in the Thames Estuary, London was a Second Rate ‘Large Ship’ built in Chatham in 1656 during the Interregnum. She is known for having formed a part of the English Squadron sent to collect Charles II from the Netherlands and restore him to his throne in an effort to end the anarchy which followed the death of Cromwell in 1658.
