RoxAnn Ground Truthing Video Drops 1997
The purpose of this data capture was to increase the available information of species and habitats, thus extending the area covered by survey within the Pen Llyn a'r Sarnau Special Area of Conservation (SAC). Results of a survey carried out from the Prince Madog Research Vessel as a joint operation by the University of Wales, Bangor and Countryside Council for Wales (CCW). Using RoxAnn, ground truthing video transects within the Pen Llyn a'r Sarnau SAC were recorded.

Video equipment was towed behind the Prince Madog recording species and limited substratum along each transect. The nature of the video drops made it difficult to accurately record species abundances or substratum percentages. Abundances for species have been assigned from the description given on the video recording forms: S= Any noted as superabundant; A= Any noted as abundant; C= Lots, many patches; F= Quite a lot, patches; O= Sparse, few, sparse patches; R= Very sparse, very few [SACFOR]. Substratum is detailed in the habitat description.
