A survey of the subtidal physical and biological features of the VEHEAP Harbours area (Victoria and Esquimalt Harbour, Gorge and Portage Inlet and Esquimalt Lagoon) with the intent of mapping the general distribution and position of physical and biological features for both inventory and harbour management purposes. The distribution of coarse shell material (>2.0mm) on the surface of the seabed, based on visual classification of each second of the video imagery for the survey area. The shell material is classified visually and mapped in one of five cover categories: Cover Codes: 5-30% = Sparse Cover; 30-80% = Low-moderate; >80% = Dense; vegetation = Dense Vegetation - substrate obscured; wood = Wood debris - substrate obscured; no survey |
