This review evaluates present and past rates of coral growth and net vertical accretion in relation to predicted, present and past rates of sea-level rise. It also considers potential constraints on future reef performance and the complexities
of reef response to environmental disturbance, and shows how the interaction of geological history and contemporary process climate determines local reef island responses.
The two variables discussed, which will contribute to the understanding of the global role of coralreefs, are : 1) remote sensing of submerged coralreefs in general; and 2) remote sensing of coral bleaching in particular. A summary of radiative
Coralreefs and islands and predicted sea-level rise
This paper examines the likely response of coralreefs to future sea-level change over the time scale of 102 years, in the light of what is known of reef growth rates and reef response to sea-level change in the historical record, especially since
the late glaciation, and of the contemporary growth rates of reefs. Given the present imprecision of attempts to estimate future sea-level rise, the A. suggests broad response rates of reefs to various potential sea-level scenarios.

unity to all the work Current ideas and data are summarized and it is indicated where contrary views exist This clear and well-illustrated book is recommended not only to students, but also to anyone working on coralreefs and on Quaternary sea-level
Frequentslope failures of the forereef dropoff occur in living coralreefs on the island of Bonaire in the southern Caribbean. Topographic profiles of 10 sites were taken perpendicular to shore, followed by an estimation of coral ages along
the topographic profiles. Comparisons of coral age and adjacent slope angle indicated that the steeper slopes are older and that mass failure of the slope reduces the steepness of the forereef front and destroys the coral community along the disturbed slope
The coralreef terraces of Huon Peninsula in Papua New Guinea at 6°S range from the Holocene terrace I to the more than 300,000 years old terrace XI. Since the ages of the coralreefs are known, a chronosequence of the different pedogenetic

Field experiments were conducted to investigate the refraction and propagation of ocean waves across 2 coralreef platforms in the Maldives, central Indian Ocean. Seven pressure sensors were deployed on each reef to quantify temporal and spatial
mechanism controlling the transformation of wave energy across the reefs. Results provide the first field-based validation of wave refraction and convergence on coralreefs and have significant implications for sedimentation processes and the formation
variations in wave characteristics across the platform surfaces. Directional wave properties were calculated from high frequency wave and current records obtained at 2 locations on each reef and corroborate theoretically predicted propagation pathways derived
from an analytical wave refraction model. Results demonstrate that reef geometry critically controls the refraction and propagation behaviour of incident swell across the reef structures. Furthermore, wave focussing has been identified as a major

The Holocene terraces described here are erosional features with regressive encrusting corals, developed upon the Holocene transgressive reef. The multiple levels represent episodic, probably coseismic uplift, which has occurred repeatedly
