This marine geophysical and multibeam survey was undertaken by British Geological Survey on behalf of Marine Scotland utilising the Northern Lighthouse Board vessel NLV Polestar, it took place in July/August 2012 off south-west Tiree. The purpose was to further our understanding of Scotland’s marine environment, increase the efficiency of use of public resources, enhance the safety of those at sea and contribute to new policy priorities such as marine protected areas, wider conservation measures, marine planning and renewable. Bathymetric data was collected using a Kongsberg EM3002D dual head, multibeam system. Data was acquired using a Kongsberg SIS operating system, logging raw .ALL files. This data was processed offline by BGS using CARIS HIPS and SIPS 7.1 SP2.

High resolution composite DTM based on multi beam surveys in German Bodden waters. All data acquired in 2016.

This marine multibeam survey took place in July 2011 in the area around the Isle of Canna on the west coast of Scotland on board the Northern Lighthouse Board vessel NLV Pole Star. The survey was carried out by the British Geological Survey (BGS) on behalf of Marine Scotland and Scottish Natural Heritage (SNH). Sea floor bathymetry data were collected using a Kongsberg EM3002D multibeam system.
