The biomass of algal detritus (or detached algae on the bottom) is
measured within each of the six quadrats (1 meter squared) on each
transect. All algal detritus within each quadrat is collected by a
diver and placed in a mesh bag with a quadrat identification label. If
portions of the detritus extend beyond the boundaries of the quadrat,
then only those portions within the quadrat are collected. The mesh
bags containing detritus are brought back to the laboratory where the
detritus is sorted to species and blotted dry and weighed.
