Oakhaven Hospice

Spectrum 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.


Intertidal 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.

London 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.

The London was blown up accidentally on passage from Chatham in March 1665. Approximately 300 people are thought to have died.
