British Geological Survey (BGS) scientists took to the skies in October to study the geology and environment of the Isle of Wight and Lymington areas.
The BGS carried out a low level airborne survey of the Isle of Wight and Lymington areas. The aircraft, a De Havilland Twin Otter, has a distinctive red and white striped tail-plane and registration OH-KOG. It flew along a regular series of lines 200 metres (656 ft) apart, oriented north-south and at a height no lower than 56 metres (185 ft) as it gathered information on the local geology and environment.
The most important measurements of this particular survey are made with an electromagnetic system; this records variations of electrical conductivity in the shallow earth which may reflect land quality. The plane's other sensors measure magnetism, which can indicate rock type and structure, and natural gamma spectrometry, which reflects mainly the type and condition of the soils.
