The evidence from shallow coring, surface geomorphology, lithology of exposed rocks, superficial sediment accumulations, vegetation patterns, and the historical record derived from radiometric dating to suggest a sequence of reef and island development on the northern Great Barrier Reef in Holocene time as discussed by the authors.Abstract:
This paper brings together the evidence from shallow coring, surface geomorphology, lithology of exposed rocks, superficial sediment accumulations, vegetation patterns, and the historical record derived from radiometric dating to suggest a sequence of reef and island development on the northern Great Barrier Reef in Holocene time. Reefs initially grew vertically as the sea rose rapidly from glacial low levels. This continued until vertical growth was limited by the air/sea interface as the rate of sea level rise slowed. Vertical growth was then replaced by reef flat formation at low intertidal levels, and by the lateral extension of reefs, especially to leeward. Superficial sediment accumulations on the reef flat define a series of changing habitats for further organic growth, and also record the sequence of Holocene events. Controls of the transition from vertical to horizontal reef growth will be discussed and some comments offered on latitudinal variation in reef form along the Great Barrier Reef.read more

The Geomorphology of the Great Barrier Reef: Development, Diversity and Change
TL;DR: This paper reviewed the history of geomorphological studies of the Great Barrier Reef and assessed the influences of sea-level change and oceanographic processes on the development of reefs over the last 10,000 years.

The geological effects of hurricanes on coral reefs and the interpretation of storm deposits
TL;DR: This article found that the abundance of reef flat storm deposits whose ages cluster around 3000-4000 y BP in certain parts of the world most likely relate to a slight fall in relative sea level rather than an increase in storminess during that period.

The impact of sea-level rise on mangrove shorelines:
TL;DR: In this article, Stratigraphic studies of the sediments underlying both the mangrove forests themselves and associated wetlands indicate that there have been considerable changes in the extent of these wetlands as a result of past sea-level fluctuations.

The role of hurricanes in the development of reef islands, Ontong Java atoll, Solomon Islands
TL;DR: In this paper, the effects of a hurricane in 1967 are analysed through detailed field mapping in 1971, 1972 and 1986, and with reference to evidence from earlier charts and air photographs, concluding that the hurricane represents a high-magnitude low-frequency event necessary for the long-term replenishment of sediment on shorelines, but that in the short term such storms will seem to have mainly destructive effects.

Late Quaternary Sea-Level Studies in Micronesia: CARMARSEL Expedition
TL;DR: The CARMARSEL Expedition to Guam and the Caroline and Marshall Islands has provided substantial evidence of a difference between islands in tectonically active and inactive belts as mentioned in this paper, showing that coral reefs have been elevated above the present sea level, whereas the 33 islands visited in the apparently more stable belt to the east of Guam failed to show any elevated reefs.

Facies Geometries Within Pleistocene Reefs of Barbados, West Indies
TL;DR: In this paper, a broad-scale approach was taken by determining facies relations, and the geometry of facies composing the individual reef tracts were treated as single carbonate bodies, showing that the areal distribution of reef-tract trends conforms to the outlines of topographically high areas of the island.

TL;DR: A clean seacliff section 8 m high provides detailed evidence of the relationship between reef development and early Holocene sea-level changes, relative to the rising coast of Huon Peninsula, Papua New Guinea.
