Multibeam bathymetry survey between Start Point and West Rutts in 2012
A multibeam bathymetry survey of a previously unsurveyed area of seabed, carried out in 2012 between Start Point and West Rutts. This is within the Start Point to Plymouth Sound and Eddystone Reefs candidate Special Area od Conservation (cSAC) off South Devon. Together, the inshore and offshore elements of the survey work will form the basis for mapping extent and assessing baseline conditions of features to allow any future changes in condition to be detected. The work will build on the initial surveys of the area, which have provided the information upon which Natural England have recommended to Defra that these sites be designated as candidate SACs, under the Habitats Directive.

In 2012 Cefas Endeavour gathered multibeam data with associated backscatter data from the areas not covered in the acoustic survey carried out by Cefas in early 2011 between Start Point and West Rutts. All survey at the Start Point area was conducted using both the EM2040 and EM3002D multibeam systems to ensure compatibility with prior survey using the EM3002D system. The multi-beam data were processed using Caris Hips and Sips Ver7.1.1 service pack 1. A total of 55 lines were imported into Caris, where kinematic tidal adjustments were applied and some basic filtering. Overall the data was good and relatively clean with a few areas of noise that needed manual cleaning. Geotiffs were produced as well as an xyz file and the GSF files. The 55 lines of data equates to 344km of multi-beam data. The Geotiff was produced at a resolution of 1m with a vertical exaggeration of 6 and the colour map rainbow.The backscatter data were produced using Fledermaus FMGT v7.32. The backscatter Geotiff was produced at 0.75m resolution in one tile and at 0.3m resolution in 19 tiles.
