Scottish Natural Heritage (SNH) Multibeam Survey 2011/7_SNH: Canna (01/Jul/2011 to 11/Jul/2011)

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. These data are archived by BGS. Technical details of the survey are contained in the BGS Report of Survey (OR/11/045), http://nora.nerc.ac.uk/id/eprint/516268/

Statement
British Geological Survey was contracted to undertake the survey on behalf of Scottish Natural Heritage. NAVIGATION: Applanix POS MV 320 with DGPS corrections from a Fugro SeaSTAR receiver. TIDE GAUGE: Valeport Midas WLR, Tide gauge height relative to chart datum was determined using a Leica GPS500 system, Leica Geo Office software and the freely available RINEX data from the Ordnance Survey website. It was possible to measure the tide gauge height and reference this to chart datum. The Admiralty chart for this area notes that Chart Datum for Loch Harport is 2.6 m below Ordnance Datum Newlyn. Loch Harport was the nearest location where a CD to OD Newlyn offset could be found. Using ellipsoidal height and VORF (Vertical Offshore Reference Frame, provided by UKHO) the height of tide gauge relative to CD was calculated. MULTIBEAM: Kongsberg EM3002D dual-headed system capable of producing up to 508 dynamically focused beams; this produces a swath width of up to 200° operable in depths of up to 150 m. The system operates in the 300 kHz frequency range, which ensures narrow beams and a small acoustic footprint, and is also robust under conditions with high particle content in the water column. For more detailed information on the acquisition equipment and data collection techniques, operational standards, data processing methods and quality control procedures used on this survey see the Report of Survey/Cruise Report and associated documentation where available. The information available may vary depending on the age of the survey. Data are checked and loaded to the BGS Coastal and Marine data management system following BGS marine data management procedures.
