Fujita, K, Yagioka, N., Nakada, C., Kan, H., Miyairi, Y, Yokoyama, Y. and Webster, J.M. Reef-flat and back-reef development in the Great Barrier Reef caused by rapid sea-level fall during the Last Glacial Maximum (30–17 ka) (Geology 10.1130/g46792.1)
This new paper builds directly on the Nature and Nature Geoscience papers we published last year on the IODP Exp. 325 and provides yet more insights in how the GBR grew during the Last Ice Age ~ 20,000 years ago. Rather than barrier reefs like we have now the GBR during the ice age was actually a mature fringing reef system with shallow back-reef lagoons that were accumulating at rates comparable to those during our Holocene highstand. Kazu and the team used large benthic forams (LBF’s) assemblages combined with extensive C14-AMS dating to reconstruct the deposition of these fascinating deposits.
Bravo Kazu and the team!
