Inter-reefal Halimeda communities from the far north to southern sections of the Great Barrier Reef were sampled: 1013 Van Veen grab samples from 281 stations, and 76 biomass samples collected by scuba divers from 12 stations. Halimeda, Udotea and Penicillus plants were air-dried, sorted into species, oven-dried and weighed. Organic content was calculated from weight loss after overnight combustion in a muffle furnace.

Halimeda communities were differentiated as meadow, mound, and shoal. Species compostion variables were: location, % (of calcareous green algae); where found (within/outside meadows); other plant macrobiota was also recorded.

Variables on biomass were: station location and number of samples; means of collection (grab, diver); area (m2); depth (shallow, <50 m; deep).
