These MoUs provide the basis for the collaborative survey of Scotland’s seas in order 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 too new policy priorities such as marine protected areas, wider conservation measures, marine planning and renewables. This report details a marine survey undertaken by the British Geological Survey (BGS) on behalf of Marine Scotland, utilising the Northern Lighthouse Board Vessel the NLV Polestar from the 23rd of July to 6th of August 2012. The report details the operational aspects of the survey to the South West of Tiree using Surface Tow Boomer (STB) and Multibeam Echosounder (MBES) equipment. There is no geological interpretation of the data. The BGS staff involved were: Rhys Cooper; Kirstin Crombie; Simon Ritson; David Wallis and contract Hydrographer Gillian Horner.

Data was acquired using a Kongsberg SIS operating system, logging raw .ALL files. This data was processed offline using CARIS HIPS and SIPS 7.1 SP2. Backscatter mosaics were created using Fledermaus GeoCoder FMGT. The position of the vessel was obtained from an Applanix POS MV 320 with DGPS corrections from a Fugro SeaSTAR receiver. A Valeport TideMaster tide gauge was installed on Tiree and all depths were reduced to Chart Datum. UKHO’s VORF model was used to define the relationship between the ETRF 89 ellipsoid height measured at the tide gauge and Chart Datum. Sound velocity profiles were undertaken at a maximum interval of twelve hours or as required. The Northern Lighthouse Boards own sound velocity profile (SVP) probe was used. The EM3002D has a SV sensor mounted at the heads providing a real-time indication of sound velocity at the transducer face. Seismic data was collected using an Applied Acoustics Surface Tow Boomer (STB) and BGS Hydrophone summing amplifier and pre-filter. CODA DA2000 was used as the acquisition system and CODA GeoSurvey for processing.
