Uncertainty remains about the effect of nutrients on the Great Barrier Reef as monitoring in remote locations remains difficult, expensive and rather sporadic. Here we aim to develop a sensitive and continuous monitoring technique. The availability of such a technique will allow more appropriate monitoring of nutrient inputs. This will facilitate appropriate application of nutrients, in the form of agricultural fertilizer and sustainable land management practices in order to minimize the risk of nutrients to the environment and humans.Read moreRead less

The Pioneer Valley Water Resources Plan, part of the Council of Australian Government's Water Reform Process, includes the development of regional groundwater flow and saltwater intrusion models for assisting in the allocation and management of the groundwater resources. The ocean forms the largest active boundary of the Pioneer groundwater system, where complex, dynamic hydraulic conditions exist due to oceanic oscillations (tides and waves) and density effects. This project aims to investigate and quantify the effects of the dynamic seaward boundary condition on regional groundwater flow in Pioneer Valley aquifers. The research outcomes will also have important implications for other coastal aquifers.Read moreRead less
Quantifying the pathways and fluxes of iron to Moreton Bay. Recent investigations into the blooms of Lyngbya majuscula in Moreton Bay have identified dissolved iron, phosphorus and humic substances as important triggers of blooms. These chemicals are most likely sourced from land activities and transported by surface and ground water into the bay. Quantification of the groundwater discharge and associated chemical input to the bay has been identified by the Lyngbya Scientific Panel and the Lyng ....Quantifying the pathways and fluxes of iron to Moreton Bay. Recent investigations into the blooms of Lyngbya majuscula in Moreton Bay have identified dissolved iron, phosphorus and humic substances as important triggers of blooms. These chemicals are most likely sourced from land activities and transported by surface and ground water into the bay.

Salt marshes play an essential role in maintaining Australia's coastal bio-diversity. They also function as barriers to fluxes of terrestrial pollutants to our coastal sea. Australia has a large number of salt marshes listed by the Ramsar Convention as coastal wetlands of international importance but many of them are subject to loss and degradation due to competing land uses. This project, examining in detail the flow and transport processes in marsh soils, will lead to (1) better understanding of the marsh's response to anthropogenic stress; and (2) improvement of strategies and methods for marsh wetland preservation and restoration.Read moreRead less
