Burt Fuiava demonstrating how to use Rugosity to measure the amount of habitat available for marine animals to live in. Rugosity is a measure of complexity, rugosity is presumed to be an indicator of the amount of available habitat available for colonization by benthic organisms (those attached to the seafloor), and shelter area for mobile organisms. After Burt's demonstration we went in the water and practice how to use this monitoring method at our three 25m transects that Ephraim, Senifa and Ching set up to do our practice.
