“…The results of this study confirm faunal changes during a sea-level rise observed in present-day and fossil mixed terrigenous-carbonate lagoons and/or rimmed carbonate platforms (Kuhn 1984;Gardulski et al 1986;Belperio and Searle 1988;Crevello 1991;Peerdeman and Davies 1993;Blomeier and Reijmer 1999;Hillgärtner 1999;Strasser et al 1999;Gischler 2003). An almost similar facies succession in response to the Holocene sea-level rise, like for the proximal-and mid-lagoonal settings within the lagoon of Mayotte, is found in the North-lagoon of Bermuda (Kuhn 1984).…”

“…Kuhn (1984) documented a similar Holocene TST faunal succession in the proximal and middle North-lagoon of the Bermuda Islands. The dominance of suspension feeders, like molluscs, echinoderms, bryozoans and ostracods, in transgressive deposits with high terrigenous input and thus nutrient concentrations also has been documented in numerous fossil sedimentary systems (Belperio and Searle 1988;Hallock and Schlager 1986;Harris et al 1990;Crevello 1991;Blomeier and Reijmer 1999;Hillgärtner 1999;Strasser et al 1999).…”

This paper documents the facies change in response to the Holocene transgression within five sediment cores taken in the lagoon of Mayotte, which contain a Type-1 depositional sequence (lowstand, transgressive and highstand deposits underlain by an erosive sequence boundary). Quantitative compositional analysis and visual examination of the bioclasts were used to document the facies changes. The distribution of the skeletal and nonskeletal grains in the lagoon of Mayotte is clearly controlled by (1) the rate and amplitude of the Holocene sealevel rise, (2) the pre-Holocene basement topography and (3) the growth-potential of the barrier reef during sea-level rise, and the changes in bathymetry and continuity during this period. The sequence boundary consists of the glacial karst surface. The change-over from the glacial lowstand is marked by the occurrence of mangrove deposits. Terrigenous and/or mixed terrigenous-carbonate muds to sandy muds with a mollusc or mollusc-ostracod assemblage dominate the transgressive deposits. Mixed carbonate-siliciclastic or carbonate sand to gravel with a mollusc-foraminifer or mollusc-coral-foraminifer assemblage characterize the early highstand deposits on the inner lagoonal plains. The early highstand deposits in the outer lagoonal plains consist of carbonate muds with a mollusc-foraminifer assemblage. Late highstand deposits consist of terrigenous muds in the nearshore bays, mixed terrigenous-carbonate sandy muds to sands with a mollusc-foraminifer assemblage on the inner lagoonal plains and mixed muds with a mollusc-foraminifer assemblage on the outer deep lagoonal plains. The present development stage of the individual lagoons comprises semi-enclosed to open lagoons with fair or good water exchange with the open ocean.

“…The isopach map produced by Fielding et al (2006) also suggested that nearly all Holocene sediment delivered by the Burdekin River is stored within the Burdekin Delta rather than being dispersed into the GBR. However, when flows exceed ~2000 m 3 s -1 , a turbid plume is visible on the inner shelf, extending up to 10 km offshore (Belperio, 1983;Wolanski and van Senden, 1983). Most recently, Lewis et al, (2014) A C C E P T E D M A N U S C R I P T…”

“…The islands are surrounded by a patchwork of fringing reefs with relatively high coral cover (~67%) compared to the rest of the Great Barrier Reef [3]. Radio carbon dating of similar reefs ~100 km to the north (Percy Islands) suggests that reefs in the Keppel group are relatively young, having developed only ~1500 years ago in the late Holocene following landward migration of the terrigenous sediment wedge and sea level fall [43,44]. Keppel Bay is essentially an ancient flood plain, in-filled with accumulated coastal sediment from the Fitzroy River following sea level rise in the early Holocene (~9000 years ago).…”

Species Richness and Community Structure on a High Latitude Reef: Implications for Conservation and Management

Abstract:In spite of the wealth of research on the Great Barrier Reef, few detailed biodiversity assessments of its inshore coral communities have been conducted. Effective conservation and management of marine ecosystems begins with fine-scale biophysical assessments focused on diversity and the architectural species that build the structural framework of the reef. In this study, we investigate key coral diversity and environmental attributes of an inshore reef system surrounding the Keppel Bay Islands near Rockhampton in Central Queensland, Australia, and assess their implications for conservation and management. The Keppels has much higher coral diversity than previously found. The average species richness for the 19 study sites was ~40 with representatives from 68% of the ~244 species previously described for the southern Great Barrier Reef. Using scleractinian coral species richness, taxonomic distinctiveness and coral cover as the main criteria, we found that five out of 19 sites had particularly high conservation value. A further site was also considered to be of relatively high value. Corals at this site were taxonomically distinct from the others (representatives of two families were found here but not at other sites) and a wide range of functionally diverse taxa were present. This site was associated with more stressful conditions such as high temperatures and turbidity. Highly diverse coral communities or biodiversity 'hotspots' and taxonomically distinct reefs may act as insurance policies for climatic disturbance, much like Noah's Arks for reefs. While improving water quality and limiting anthropogenic impacts are clearly important OPEN ACCESSDiversity 2011, 3 330 management initiatives to improve the long-term outlook for inshore reefs, identifying, mapping and protecting these coastal 'refugia' may be the key for ensuring their regeneration against catastrophic climatic disturbance in the meantime.
