The Southern Ocean's response to abrupt climate change. This project aims to determine how the Southern Ocean responds to abrupt climate change, through geochemical analysis of marine sediment cores. Rapid warming events of the last ice age provide an analogue to human-caused warming. Experiments using ocean climate models will evaluate the drivers and consequences of the biogeochemical response of different sectors and zones of the Southern Ocean. The intended outcome is a better understanding ....The Southern Ocean's response to abrupt climate change. This project aims to determine how the Southern Ocean responds to abrupt climate change, through geochemical analysis of marine sediment cores. Rapid warming events of the last ice age provide an analogue to human-caused warming. Experiments using ocean climate models will evaluate the drivers and consequences of the biogeochemical response of different sectors and zones of the Southern Ocean. The intended outcome is a better understanding of how and why climate change impacts ocean productivity in the ecologically significant Southern Ocean. This will lead to better representations of carbon feedbacks in climate models and more robust projections of future climate change.Read moreRead less
A changing climate for calcification on the Great Barrier Reef: past, present and future. The Great Barrier Reef (GBR) is a national and international icon, recognised through its inscription as a World Heritage Area and economic and social value to Australians. Maintenance of the GBR as we know it is now compromised by a rapidly changing climate. Ocean acidification, warming water temperatures and increased freshwater will progressively be detrimental to the fundamental reef-building process ....A changing climate for calcification on the Great Barrier Reef: past, present and future. The Great Barrier Reef (GBR) is a national and international icon, recognised through its inscription as a World Heritage Area and economic and social value to Australians. Maintenance of the GBR as we know it is now compromised by a rapidly changing climate. Ocean acidification, warming water temperatures and increased freshwater will progressively be detrimental to the fundamental reef-building process of calcification. Informed policy and management strategies in a rapidly changing physical environment require determination, for short and long time frames, of the regional consequences and impacts of changing reef-building capacity.Read moreRead less
Indian Ocean Climate Change: Ningaloo Reef, a litmus test for the survival of coral reefs. Coral reefs are at the frontline from the effects of rapidly rising levels of carbon dioxide that is causing both global warming and oceans to become more acid-like. Our research program will determine how the survival of one of the World’s most pristine and best preserved coral reefs, Ningaloo Reef, is linked to the response of Australia’s Indian Ocean to climate change. For the first time, we will simula ....Indian Ocean Climate Change: Ningaloo Reef, a litmus test for the survival of coral reefs. Coral reefs are at the frontline from the effects of rapidly rising levels of carbon dioxide that is causing both global warming and oceans to become more acid-like. Our research program will determine how the survival of one of the World’s most pristine and best preserved coral reefs, Ningaloo Reef, is linked to the response of Australia’s Indian Ocean to climate change. For the first time, we will simulate realistic ‘future’ conditions and see how actual coral reef systems respond. This will provide a ‘yardstick’ against which the best-case survival potential of the world’s coral reefs can be assessed, critical for underpinning the urgently needed action to reduce greenhouse gas emissions if we are to ensure the survival of coral reefs.Read moreRead less
