Title

Scottish Natural Heritage (SNH) Multibeam Survey: Loch Alsh, Loch Duich, Long Long, Kyle Rhea (04/Mar/2013 to 17/Mar/2013)

Abstract

This marine multibeam survey took place in March 2013 within the MPA (Marine Protected Area) proposal area of the Lochs Duich, Long and Alsh and the additional area of the Kyle of Rhea on board the RV White Ribbon. The survey was carried out by the British Geological Survey (BGS) on behalf of 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 CR/13/033.

Lineage

British Geological Survey was contracted to undertake the survey on behalf of Scottish Natural Heritage. The White Ribbon was equipped with a Kongsberg EM3002D dual head, multibeam echosounder system (MBES). Data were acquired using the Kongsberg SIS operating system, logging raw .ALL files. These data were processed offline by BGS using CARIS HIPS and SIPS 7.1 SP2. Individual field sheets were created for Loch Long, Long Duich, Long Alsh and Kyle Rhea. Backscatter mosaics were created in Fledermaus Geocoder FMGT. All final bathymetric surfaces were produced with a 2m resolution. The backscatter mosaic was generated at 1m resolution. A range of bathymetric products were created in ArcGIS and Fledermaus using the processed output from CARIS and Fledermaus FMGT. See BGS Report of Survey CR/13/033 for further information.
