Long-term changes in Mackay-Whitsunday water quality and connectivity between coral reefs and mangrove ecosystems

· Jun 6, 2013 · Leave a Comment

Declining water quality is implicated in the degradation of near-shore Great Barrier Reef (GBR) ecosystems. The goal of this project is to provide a definitive answer to the question of how GBR water quality has changed since European arrival (pre- 1860). Using novel geochemical proxies in long-lived coral cores and innovative remote sensing techniques, we will develop quantitative histories of water quality and mangrove distribution change. This project will deliver the first integrated assessment of how coastal water quality and associated ecosystems have varied historically, which will be immediately applicable for long-term management of coastal ecosystems lining the GBR.

Modelling the impact of coral bleaching on coral ecosystem function

· Jun 6, 2013 · 1 Comment

As the function of coral reefs is altered by the impacts of coral bleaching and the associated changes in nutrient processes and budgets, it is important that we are able to assess the response sensitivities and likely outcomes of management interventions aimed at mitigating human impacts. In the same way, it is essential that we are able to identify our knowledge gaps from a strategic perspective and also engage stakeholders in the process of assessing and deciding on the best strategies for future initiatives. Dynamic system models provide an interface and process based pathway for integrating these issues into an ecosystem level framework which allows consensus to be reached among stakeholders as to which approach and/or initiative is likely to be most cost effective and strategically sound.
