This project seeks to build the capacity of the diving community at the University of Victoria and Memorial University to undertake detailed and rigorous monitoring of our coastal marine resources by training eight divers in standardized quantitative surveys consistent with Reef Life Survey.
RLS relies on highly skilled divers trained in underwater visual census to survey transects (50 m lines) in duplicate 5-m strips on either side (total area surveyed = 500 m2). Mobile macrofauna (fish and invertebrates) are counted and sized, sessile invertebrate and macroalgal cover are estimated as percent cover, and images are captured for verification of habitat type and complexity.
