The historical representation and near-future (2050) projections of the Coral Sea current system in CMIP6 HighResMIP Open
The Coral Sea houses expansive coral reefs. Reef health is inextricably linked to water temperatures, which are regulated by the hydrodynamic environment. The ocean current system in the Coral Sea is dominated by jets of the South Equatori…

Ocean alkalinity enhancement in a coastal channel: simulating localised dispersion, carbon sequestration and ecosystem impact Open
Ocean Alkalinity Enhancement (OAE) is a proposed marine carbon dioxide removal (mCDR) method that has the potential to sequester CO 2 at the gigaton scale. Alkaline substances are added to the surface ocean to strengthen the air-sea pCO 2 …

Drivers of upwelling events and biological responses in the far Northern Great Barrier Reef region. Open
Upwelling events along the northern shelf edge of the Great Barrier Reef (GBR) are key drivers of ecosystem health and resilience. Understanding the timing, frequency, and drivers of these upwelling events are critical for predicting ecosy…

The effect of natural and anthropogenic nutrient and sediment loads on coral oxidative stress on runoff-exposed reefs Open
Recently, corals on the Great Barrier (GBR) have suffered mass bleaching. The link between ocean warming and coral bleaching is understood to be due to temperature-dependence of complex physiological processes in the coral host and algal s…

Impact of catchment-derived nutrients and sediments on marine water quality on the Great Barrier Reef: An application of the eReefs marine modelling system Open
Water quality of the Great Barrier Reef (GBR) is determined by a range of natural and anthropogenic drivers that are resolved in the eReefs coupled hydrodynamic - biogeochemical marine model forced by a process-based catchment model, GBR D…

Optimising cool-water injections to reduce thermal stress on coral reefs of the Great Barrier Reef Open
Coral bleaching driven by ocean warming is one of the most visible ecological impacts of climate change and perhaps the greatest threat to the persistence of reefs in the coming decades. In the absence of returning atmospheric greenhouse g…
