Metadata 1) Title : Percent Visual Cover on Long Term Reefs. 2) Abstract : Coral, algae, and invertebrates were observed, and their percent cover on each of the patch reefs estimated. These data were collected from 2003 2005, 2007, 2009 and 2012 at each patch and at each site. Descriptions of each reef are located in the Reef Me asurements data. Estimating benthic composition of each reef provides serial data over time and space. These data are meant to provide contextual information for vermetid and Thalassoma dynamics.

Updated 5/2/12 9:19 AM UF Moorea Data Percent Visual Cover Protocol Title: Long Term Reef Percent visual cover Overview: To facilitate our understanding of habitat quality over space and time. General Procedure: One person swims around the reef and visually estimates the relative cover of different substrates. In early years there was some confusion about Stegastes turf and grazed turf (Surgeonfish fish grazed turf). By 2012, grazed turf is now considered bare spa ce. Divers i gnored taxa that covered less than 1 percent of the benthos in 2003 and 2004. Starting in 2005, they looke d at cover of 2% and above. In 2004, additional lettered reefs were monitored for benthic cover. These lettered reefs were experimentally added to the site for another experiment. After 2004 they were not monitored again. For a limited number of reefs between 20032005, the investi gators completed a limited number of point contacts to verify their estimates, see PointContact metadata, protocol and data for more details. Materials: Diver, slate Solutions/Reagents (if applicable): Procedure: Calculations: To get total point s estimated, sum the columns. Use that sum to estimate percent cover each substrate by dividing the number in the cell by the total points.
