Relationships between reef growth and sea level in the Great Barrier Reef in Proceedings. Volume 3. Symposia and seminars.
This overview of the Great Barrier Reef area shows that different parts of the same reef may have responded differently to sea-level change. The new terms keep-up reefs, catch-up reefs, give-up reefs are proposed. The conditions of reef initiation
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.
Coral reefs and islands and predicted sea-level rise
This paper examines the likely response of coral reefs 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.

This review summarizes the results of recent physical process studies in the Great Barrier Reef Marine Park established under the GBRMP Act (1975), with emphasis on relationships with the terrestrial environment, hydrodynamics, sediment movement
and processes operating within the reef framework.

Structure and development of a windward fringing reef, Orpheus Island, Palm group, Great Barrier Reef in Proceedings. Volume 3. Symposia and seminars.
The northern part of the reef has grown upward with the rise in sea level, reef flat development commencing prior to 6000 yr BP. The southern part is considerably younger. (Author).
Reef response to sea level rise: keep-up, catch-up or give-up in Proceedings. Volume 3. Symposia and seminars.
In keep-up reefs the growth rate tracks the sea-level rise rate. Catch-up reefs can grow up and catch-up with sea level. Give-up reefs are relicts in which rise rate has declined or ceased. These three types of reefs have distinct external
The carbonates around the town of Palmi show the most continuous reef developments, which extend for about 5 km in a NNE-SSW direction. This trend is parallel to the strike of the staircased system of normal faults which characterizes the coastline
Die Entwicklung von Riffen als Folge von Meeresspiegelschwankungen. (The development of reefs as a sequence of variations of the sea level)
Reefs get more and more importance in many countries because great deposits of oil and gas can be connected with them. In this paper a model for the development of reefs basing on a comparison of fossilized and recent reefs of all continents
Reef growth and sea-level change: The environmental signature in Proceedings. Volume 3. Symposia and seminars.
Great contrast occurs between the sea-level signatures of the Caribbean (continuous Holocene rise) and the southern Pacific (almost a standstill for some 6000 years). In both regions, however, there may be responses in terms of reef growth
and ultimately reef structure, independent of the direction and rate of sea-level change, with reefs responding to the Holocene transgression by keeping-up, while other reefs catch-up or give-up. The use of sea level marks in the interpretation of ancient reefs
Field observations of wave refraction and propagation pathways on coral reef platforms

Field experiments were conducted to investigate the refraction and propagation of ocean waves across 2 coral reef platforms in the Maldives, central Indian Ocean. Seven pressure sensors were deployed on each reef to quantify temporal and spatial
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
mechanism controlling the transformation of wave energy across the reefs. Results provide the first field-based validation of wave refraction and convergence on coral reefs and have significant implications for sedimentation processes and the formation

Stratigraphy and chronology of late Pleistocene reefs in the southern Cook Islands, South Pacific
The AA. concentrate upon recognition of individual reef units within the late Pleistocene Makatea limestones, and dating of corals from them by U-series disequilibrium dating. They demonstrate variability in the elevation of contemporaneous reefs

Cheniers and oyster reefs are 2 essential components of Holocene strata on the coast of Bohai Bay. New AMS ages, obtained from the lower part of cheniers, enable the AA. to estimate the initiation of the cheniers, and confirm that the existing
