Sea Level Oscillations

Weather and currents at eight sites were measured and drogue trajectories obtained in July 1979 at Britomart Reef, a middle reef located at 18�16'S.,146� 38'E. in the central region of the Great Barrier Reef province. The longest current records (3 weeks) were obtained at two sites in passes between the Coral Sea and the Great Barrier Reef Lagoon where westerly currents modulated by tides were observed. Analysis of residuals also showed the importance of wind-driven secondary circulation. Non-tidal sea-level oscillations were very small. Shorter current records (1-10 days) at six sites in the lagoon and on the reef flat showed a predominant northerly flow, also modulated by tides and wind. A residual anticlockwise water circulation existed in the lagoon where flushing was controlled more by winds than by tides. The rise in sea level over the reef flat as a result of waves breaking was negligible. Temperature differences between air and water accounted for the cooling of the water column during the expedition. Constant south-east trade winds were experienced at the reef, while on land the wind was weaker. more variable, and often dominated by land-sea breezes.

Number Of Individuals

The structure and composition of the infauna of the coral P. damicornis in the Capricorn Group, Great Barrier Reef, is examined. A total of 40 coral heads were sampled from four localities on two reefs and 951 individuals of 101 species were extracted. This is five times the species collected from P. damicornis in previous studies. A comprehensive species list is provided. Infauna was dominated by only a few species, 20 species accounting for 78% of individuals and 36 species recorded only as single individuals. Crustacea was the dominant taxon present, comprising 72% of species and 86% of individuals. Number of species and number of individuals show significant regressions with size of coral heads. Differences in physical environment at the four sites did not affect species diversity within coral heads. However, several common species only occurred within particular habitats. Species diversity is discussed briefly in relation to the behaviour of resident symbionts, random pelagic settlements of larvae, the size of target corals and habitat heterogeneity in coral heads.
