Classifications include: <\/SPAN><\/P> - Tidal Scoured Mixed Sediments (Glacial till - boulders or cobble with high roundness and low angularity)<\/SPAN><\/P> - Mixed Sediments (Glacial Till - < 50% boulders or bedrock with mixed sediments of cobble, gravel and sand) <\/SPAN><\/P> - Gravelly Sand (Sand with 5\u201330% gravel)<\/SPAN><\/P> - Sand (> 90% Sand)<\/SPAN><\/P> - Silty Gravel with Anemones (> 50% gravel with silt and Anemones)<\/SPAN><\/P> - Silt (> 90% Silt) and Bedrock and Boulders (> 50% bedrock or boulders).<\/SPAN><\/P> Unsupervised classification process is as follows:<\/SPAN><\/P> 1. Image objects were produced using eCognition software (segmentation layer found in the UnsupervisedClassification_shapefiles/Segmentation_eCognition) using bathymetry and backscatter only.<\/SPAN><\/P> 2. Fuzzy c-means algorithm was applied (using PPCLUST package in R) to the segmentation layer and environmental variables to get acoutic classes (#1-14 - number of clusters were optimized at 14). <\/SPAN><\/P> 3. Bottom types from in-situ video were classified using a benthoscape classification method. 10 images at 10 meter intervals from each station were extracted and analysed.<\/SPAN><\/P> 4. Benthoscape classes from groundtruthed video data were then matched to the acoustic classes in an error matrix. <\/SPAN><\/P><\/DIV><\/DIV><\/DIV>",
