Project 3.7.2 - Connectivity and risk: tracing materials from the upper catchment to the reef

Project Leader:  Mr Jon Brodie, James Cook University

Project 3.7.2 will characterise and obtain a distinct 'fingerprint' of the fine sediments (mud fraction) and dissolved materials entering the marine environment using their isotopic and elemental properties, and link these to their sources in the major terrestrial catchments. 

The Project will also examine historical changes in the delivery of terrestrial materials, from the major river systems in the Townsville and Cairns regions, to the marine environment using coral and sediment cores.  This will involve determining the transport mechanism, residences time and fate of terrigenous sediments, nutrients and pesticides in the inshore and mid-reef regions of the Great Barrier Reef, and develop and apply new technologies to specifically trace pathways of the key nutrient elements phosphorus and nitrogen from the terrestrial catchments, through estuaries, to inshore coastal zones and to the mid-reef of the Great Barrier Reef.
