Environmental controls on the resilience of Scott Reefs since the Miocene (North West Shelf, Australia): Insights from 3D seismic data

by

North and South Scott Reefs are isolated carbonate platforms separated by an inter-reef channel on the NWS, Australia. They evolved from a barrier reef in the Miocene, and into isolated carbonate build-ups (ICB’s) during the Pliocene, and finally to the isolated carbonate platforms that continued to present day. However, the timings of coral reef turn … Read more…

Marine Geology: Tidal dynamics drive ooid formation in the Capricorn Channel since the Last Glacial Maximum

by

Relative sea-level changes can dramatically alter coastal geomorphology and coastlines, which, in turn, can fundamentally alter tidal regimes. The Great Barrier Reef (GBR) has undergone around 120 m of relative sea level (RSL) rise since the Last Glacial Maximum, ∼20,000 years ago (ka). Ooid grains (sand sized carbonate sediment) that formed in shallow water (>5 m depth) … Read more…
