Environmental Records from Great Barrier Reef Corals: Inshore versus Offshore Drivers
The biogenic structures of stationary organisms can be effective recorders of environmental fluctuations. These proxy records of environmental change are preserved as geochemical signals in the carbonate skeletons of scleractinian corals and are useful for reconstructions of temporal and spatial fluctuations in the physical and chemical environments of coral reef ecosystems, including The Great...
متن کاملPalaeoecological evidence of a historical collapse of corals at Pelorus Island, inshore Great Barrier Reef, following European settlement.
The inshore reefs of the Great Barrier Reef (GBR) have undergone significant declines in water quality following European settlement (approx. 1870 AD). However, direct evidence of impacts on coral assemblages is limited by a lack of historical baselines prior to the onset of modern monitoring programmes in the early 1980s. Through palaeoecological reconstructions, we report a previously undocum...
متن کاملAn assessment of an environmental gradient using coral geochemical records, Whitsunday Islands, Great Barrier Reef, Australia.
Coral cores were collected along an environmental and water quality gradient through the Whitsunday Island group, Great Barrier Reef (Australia), for trace element and stable isotope analysis. The primary aim of the study was to examine if this gradient could be detected in coral records and, if so, whether the gradient has changed over time with changing land use in the adjacent river catchmen...
متن کاملCoral Reefs on the Edge? Carbon Chemistry on Inshore Reefs of the Great Barrier Reef
While increasing atmospheric carbon dioxide (CO2) concentration alters global water chemistry (Ocean Acidification; OA), the degree of changes vary on local and regional spatial scales. Inshore fringing coral reefs of the Great Barrier Reef (GBR) are subjected to a variety of local pressures, and some sites may already be marginal habitats for corals. The spatial and temporal variation in direc...
متن کاملCoral records of reef-water pH across the central Great Barrier Reef, Australia: assessing the influence of river runoff on inshore reefs
The boron isotopic (δBcarb) compositions of long-lived Porites coral are used to reconstruct reef-water pH across the central Great Barrier Reef (GBR) and assess the impact of river runoff on inshore reefs. For the period from 1940 to 2009, corals from both innerand midshelf sites exhibit the same overall decrease in δBcarb of 0.086± 0.033 ‰ per decade, equivalent to a decline in seawater pH (p...
