Metadata 1) Title : Long Term Reef Physical Characteristics 2) Abstract : Reef morphological dimensions (physical characteristics) were measured in 2003, 2004, 2007, 2009 and 2012. These surveys were cond ucted at each of the 192 reefs in 2003 and 2009, and at reefs marked by letters in 2004. In 2012, each of the 198 reefs at the 12 sites monitored was measured In 2003, perce nt cover of nearest neighbor reefs were also estimated. Physical characteristic su rveys are meant to characterize the size dimensions of each reef. We ultimately hope to use these data to inform how reef size and shape influence benthic composition and Thalassoma populations.

Updated 5/2/12 9:19 AM Physical Characteristics of the 198 Reefs Title: Long Term Reef Physical Characteristics Overview: Shapes and sizes of structures can affect the settlement and dynamics of organisms associated with reefs. For example, larger reefs are expected to have higher abundances of organisms based on species/area relationships. General Procedure: Data were collected in 2003, 2007 for reefs 1192, and in 2009 and 2012 for all 198 reefs that are monitored. In 2004, letter marked reefs were monitored. A diver swims up to one of the reefs. If the reef has two distinct sections they are labeled A and B randomly. Using a transect tape the diver determines the maximum length and perpendicular width. Three height measurements are taken: From the base of the reef the div er measures the typical height of the reef and the maximum height (from the highest point). From the highest point, the diver measures the distance to the top of the water column. In 2003, the percent cover and direction of the nearest neighbor reefs were also measured.
