Cabioch et al., 2008), Belize (Gischler et al., 2000, 2010;
Purdy et al., 2003; Mazzullo, 2006), and the Australian
Great Barrier Reef (Alexander et al., 2001; Webster and
Davies, 2003; Braithwaite et al., 2004; Hopley et al., 2007).
Coring analyses of the barrier reef tract around New
Caledonia revealed the interplay between margin subsidence and eustatic sea-level variations. Combination of
lithological and paleoecological descriptions, Uranium
dating methods, magnetostratigraphy, and nannofossilbased biostratigraphy document the role of both global climate and regional tectonic history on the reef initiation
and growth of the barrier reef. Several successive lithological units were evidenced formed during the high sea
stands of the interglacial periods. It appears that the period
ranging over the last 400 ka (1 ka = 1,000 years) was probably the period of optimal conditions to explain the luxuriant reef expansion in New Caledonia over this epoch
(Flamand et al., 2008; Cabioch et al., 2008).
In French Polynesia, the Tahiti barrier reef was cored to
analyze the history of its development during the last
deglacial sea-level rise (i.e., the last 20 ka, 1 ka = 1,000
years). The first cores made in the 1990s revealed
a continuous reef growth from 14 to 6 ka from 90 m to the
reef surface (Bard et al., 1996; Montaggioni et al., 1997).
More recently, the Integrated Ocean Drilling Program
(IODP) drilled the Tahiti barrier reef in three sites to investigate reef development during the last deglacial sea-level
rise, and the evolution of the sea surface temperature during
the last deglaciation (Camoin et al., 2007).
The Belize barrier reef is another well-studied reef, but
only with short cores that document the Holocene and late
interglacial period of growth. Additional seismic and lithological data provide information on the tectonic and
eustatic controls on the Belize barrier reef development
(Mazzullo, 2006).
The Great Barrier Reef internal Pleistocene structure
remains poorly known. Davies and Peederman (1998),
Alexander et al. (2001), Webster and Davies (2003),
Braithwaite et al. (2004), and Braithwaite and Montaggioni
(2009) report limited deep coring data given the extent of
the system (see Great Barrier Reef: Origin, Evolution,
and Modern Development). The most recent studies suggest that the Ribbon Reef No 5 was initiated 770 ka ago,
followed by Pleistocene repetitive period of reef development and erosion with ten identified depositional units,
despite major fluctuations on sea level and perhaps climate.
IODP ongoing drilling (February–March 2010) should
provide new information in the near future on the development of the Ribbon Reefs in particular, and for several
other inner shelf locations as well.
