Fig 1.
The study area west of Scotland, UK.
Survey areas on the NW and SE sides of Anton Dohrn Seamount are marked. Bathymetric contours are provided by GEBCO, the 200 m depth contour (dashed line) marks the approximate position of the continental shelf break.

Camera transects sampled from the NW (top) and SE (bottom) survey areas of Anton Dohrn Seamount overlaid on multibeam bathymetry.
Selected bathymetric contours are shown as dashed lines with labelled water depths in metres below sea level.

Fig 3.
Dendrogram of hierarchical cluster analysis of species data, clusters identified using the SIMPROF routine (p < 0.01).
Dendrogram (A) shows the SIMPROF cluster results prior to splitting and consolidation of clusters and (B) shows re-labelled clusters after splitting and consolidation. Those clusters that were combined or split from Fig. 3a are labelled in red. SIMPROF clusters are collapsed for ease of interpretation and are represented by green dashed lines. Grey lines represent SIMPROF identifying with no significant internal structure.
