Environmental fingerprints of biogeochemical cycles embedded in tree rings: Linking global climate change to local long-term forest productivity. Forests cover one-third of the Earth's land surface and account for 80-90% of plant carbon and 30-40% of soil carbon. Forest carbon stocks and dynamics respond to and interact with global climate change (GCC). Recent tree ring research highlights the worsening impact of GCC and acid deposition on long-term forest productivity in central Europe. This pr ....Environmental fingerprints of biogeochemical cycles embedded in tree rings: Linking global climate change to local long-term forest productivity. Forests cover one-third of the Earth's land surface and account for 80-90% of plant carbon and 30-40% of soil carbon. Forest carbon stocks and dynamics respond to and interact with global climate change (GCC). Recent tree ring research highlights the worsening impact of GCC and acid deposition on long-term forest productivity in central Europe. This project seeks to develop and apply novel tree ring technologies for linking biogeochemical cycles of carbon and nutrients to long-term forest productivity in different regions, and to provide a scientific basis for accounting for long-term forest productivity and carbon stocks in response to future GCC.Read moreRead less
THE CORAL RECORD OF ENVIRONMENTAL IMPACTS IN THE GREAT BARRIER REEF:QUANTIFICATION OF ANTHROPOGENIC FLUXES. The objective of this proposal is to quantify the environmental impacts of enhanced terrestrial fluxes and climate change on the coral reefs in the Great Barrier Reef. This will be achieved by using an integrated approach based on coral proxy records of river plumes and sea surface temperatures that are preserved in carbonate skeletons of the long-lived (200-400 year old) Porites coral. ....THE CORAL RECORD OF ENVIRONMENTAL IMPACTS IN THE GREAT BARRIER REEF:QUANTIFICATION OF ANTHROPOGENIC FLUXES. The objective of this proposal is to quantify the environmental impacts of enhanced terrestrial fluxes and climate change on the coral reefs in the Great Barrier Reef. This will be achieved by using an integrated approach based on coral proxy records of river plumes and sea surface temperatures that are preserved in carbonate skeletons of the long-lived (200-400 year old) Porites coral. This will be integrated with monitoring and process studies of river flood plumes and coral reefs and provide a scientific basis to ensure the long-term sustainability of the GBR.Read moreRead less
Effects of physical disturbance on kelp-dominated reef communities across a broad temperate-tropical transition zone. The outcomes of this project will improve the understanding of the interactions between physical disturbances, nutrient enrichment and climate change. This addresses the national research priority of an environmentally sustainable Australia (priority goals sustainable use of biodiversity and responding to climate changes) and will contribute directly to Australia's commitments on ....Effects of physical disturbance on kelp-dominated reef communities across a broad temperate-tropical transition zone. The outcomes of this project will improve the understanding of the interactions between physical disturbances, nutrient enrichment and climate change. This addresses the national research priority of an environmentally sustainable Australia (priority goals sustainable use of biodiversity and responding to climate changes) and will contribute directly to Australia's commitments on marine ecosystem management and conservation.Read moreRead less
