Understanding of the behaviour of the nutrients controlling nuisance algae in water bodies is currently limited by the cost and logistics of collecting and analysing the large numbers of samples required.
This proposal describes the development and evaluation of portable multiparameter micro analysis systems that will be capable of high frequency measurements from a sampling vessel. This will enable environmental agencies to perform rapid on-site mapping of nutrients and other water quality parameters in large water bodies, intensive scale mapping of effluent mixing and dispersal zones, quick assessment of the impact of dredging and aquaculture, and compliance monitoring in effluent streams.

Targeting organically-complexed iron species in seawater using selective solid-phase adsorbent resins. Iron limits primary productivity in 40% of the oceans. Its accurate determination is thus critical to understanding the functioning of marine ecosystems and their role in moderating Earth's climate. Recent findings indicate that serious discrepancies exist in iron concentrations obtained using different analytical methods. These discrepancies are believed to be due to the lability of organic ....Targeting organically-complexed iron species in seawater using selective solid-phase adsorbent resins. Iron limits primary productivity in 40% of the oceans. Its accurate determination is thus critical to understanding the functioning of marine ecosystems and their role in moderating Earth's climate. Recent findings indicate that serious discrepancies exist in iron concentrations obtained using different analytical methods. These discrepancies are believed to be due to the lability of organic and colloidal iron species to extraction by adsorbent preconcentration resins. This project will design and synthesise a range of functionalised resins for the selective extraction of iron species from seawater, advancing our knowledge of its bioavailability and leading to the generation of class-specific analytical methodologies.Read moreRead less

This new state-of-the-art mass spectrometer with enhanced capability will allow Tasmanian researchers to accurately determine the elemental composition of their samples of interest. The instrument will be extremely sensitive and will be able to detect elements to very low concentrations. It will be used to support a diverse range of local research projects of international significance, for example the environmental assessment of clean and contaminated sites, chemical synthesis on a miniature scale using micro-chips, and the monitoring of selected elements of key importance for human health.Read moreRead less
