Unraveling the nitrogen cycle in a periodically anoxic estuary. Climate change is likely to lead to reduced river inflows to estuaries which can lead to oxygen depletion and major changes in nutrient cycling. This project will help inform the public and policy makers about the role of environmental flows in maintaining estuarine function, and thus guide future decisions on environmental flow requirements in the Yarra River Estuary. The benefits of this understanding will also flow on to improv ....Unraveling the nitrogen cycle in a periodically anoxic estuary. Climate change is likely to lead to reduced river inflows to estuaries which can lead to oxygen depletion and major changes in nutrient cycling. This project will help inform the public and policy makers about the role of environmental flows in maintaining estuarine function, and thus guide future decisions on environmental flow requirements in the Yarra River Estuary. The benefits of this understanding will also flow on to improved understanding and management of nitrogen loads to Port Phillip Bay. This project will form a close collaborative partnership between Monash University, Melbourne Water and the EPA. This collaboration will ensure the integration of cutting edge science with innovative management regimes Read moreRead less
Electron flow in iron hyper-enriched acidifying coastal environments: reaction paths and kinetics of iron-sulfur-carbon transformations. Iron hyper-enriched acidifying coastal lowlands have a direct social, economic and environmental impact on communities in many parts of Australia. This project will determine how iron transforms and accumulates. The new knowledge will be of immediate relevance for the remediation of coastal plains.
The Impact of Trawling on Nitrogen Removal through Sediment Denitrification in Western Moreton Bay. Nutrient enrichment of coastal waters is a national problem requiring urgent action. Sediment denitrification is one of the few natural processes capable of counteracting the process of eutrophication. Although trawling is undertaken in coastal water bodies around Australia the impact on sediment denitrification and the nitrogen budgets of coastal systems has never been considered. Many hundred's ....The Impact of Trawling on Nitrogen Removal through Sediment Denitrification in Western Moreton Bay. Nutrient enrichment of coastal waters is a national problem requiring urgent action. Sediment denitrification is one of the few natural processes capable of counteracting the process of eutrophication. Although trawling is undertaken in coastal water bodies around Australia the impact on sediment denitrification and the nitrogen budgets of coastal systems has never been considered. Many hundred's of millions of dollars are likely to be spent over the next ten years on the management of nitrogen enrichment of Australia's coastal waters. This study will quantify the impact of trawling on sediment denitrification; information which is critical for the efficient allocation of management resources.Read moreRead less
