Fig. 5From: Do Lanice conchilega (sandmason) aggregations classify as reefs? Quantifying habitat modifying effectsPatchiness. A subzone (shaded area) with identified Lanice conchilega aggregations (black) as apparent from the side scan sonar imagery. The relative coverage area (ratio of Lanice conchilega aggregations over the total area in which they occur) is 18.4% and the average aggregation reaches an area of 1.37 m2 (min 0.05 m2; max 12.31 m2)Back to article page
