The Australian Research Data Commons (ARDC) invites you to participate in a short survey about your
interaction with the ARDC and use of our national research infrastructure and services. The survey will take
approximately 5 minutes and is anonymous. It’s open to anyone who uses our digital research infrastructure
services including Reasearch Link Australia.
We will use the information you provide to improve the national research infrastructure and services we
deliver and to report on user satisfaction to the Australian Government’s National Collaborative Research
Infrastructure Strategy (NCRIS) program.
Please take a few minutes to provide your input. The survey closes COB Friday 29 May 2026.

Enhancing the performance of existing industrial enzymes through the application of new chemical modification technology. Enzymes have many uses in industry, replacing undesirable chemicals which adversely effect human & animal health & the environment. Enzymes offer advantages in effectiveness, biodegradability, specificity and safety. The concern with enzymes, in industrial applications, is that enzyme performance is degraded by a harsh chemical and/or physical environment. The aim of this stu ....Enhancing the performance of existing industrial enzymes through the application of new chemical modification technology. Enzymes have many uses in industry, replacing undesirable chemicals which adversely effect human & animal health & the environment. Enzymes offer advantages in effectiveness, biodegradability, specificity and safety. The concern with enzymes, in industrial applications, is that enzyme performance is degraded by a harsh chemical and/or physical environment. The aim of this study is to improve the performance of industrially significant enzymes by enhancing resistance to chemical & physical degradation or inactivation. This will be achieved by modifying the enzymes using new technology that we have developed. This will improve cost effectiveness of existing industrial enzymes & create opportunities for new uses of enzymes.Read moreRead less
An innovative strategy for stormwater remediation and reduction of contaminant supply from catchments. Many urbanised harbours world-wide are polluted and the main source is stormwater. Currently, emphasis is to remove gross pollutants from stormwater using numerous devices scattered through the catchment. In a radical shift from traditional approaches, we will identify primary contaminant sources in the catchment for later targeted education and regulation and a single remediation device will r ....An innovative strategy for stormwater remediation and reduction of contaminant supply from catchments. Many urbanised harbours world-wide are polluted and the main source is stormwater. Currently, emphasis is to remove gross pollutants from stormwater using numerous devices scattered through the catchment. In a radical shift from traditional approaches, we will identify primary contaminant sources in the catchment for later targeted education and regulation and a single remediation device will remove most toxic substances in stormwater currently discharged to estuaries. Stormwater reuse will provide a new valuable urban resource. This paradigm shift in traditional stormwater strategy will ensure biodiversity and ecologically sustainable development of urbanised ports. Port Jackson is used as a test case.Read moreRead less
A pilot study to demonstrate the use of 15N tracers for determining the flow of nitrogen through lower food webs. This project will have a significant impact on the way wetland wastewater treatment and reuse (WWTR) facilities are constructed in the future. Addressing the key biochemical issues to WWTR systems this study will facilitate improved construction design and management to optimise treatment performance. As National Priority One Area, sustainable water use and the efficiency of WWTR sys ....A pilot study to demonstrate the use of 15N tracers for determining the flow of nitrogen through lower food webs. This project will have a significant impact on the way wetland wastewater treatment and reuse (WWTR) facilities are constructed in the future. Addressing the key biochemical issues to WWTR systems this study will facilitate improved construction design and management to optimise treatment performance. As National Priority One Area, sustainable water use and the efficiency of WWTR systems is fundamental to our economic and social development. The results gleaned from this study will assist in the future design of WWTR systems that will be transferable outside the local study area and as such be of potential benefit both Nationally and internationally.Read moreRead less
Modelling contaminant dynamics in a well-mixed/stratified estuary. The proposed mixed/stratified estuarine model is unique and will predict effects of stormwater discharge on water quality, provide guidelines for loading from various contaminant sources, assess impact of marine construction activities, establish effects of natural and anthropogenic resuspension and determine spatial/temporal changes in contaminant distributions. Knowledge generated will assist making decisions locally and overse ....Modelling contaminant dynamics in a well-mixed/stratified estuary. The proposed mixed/stratified estuarine model is unique and will predict effects of stormwater discharge on water quality, provide guidelines for loading from various contaminant sources, assess impact of marine construction activities, establish effects of natural and anthropogenic resuspension and determine spatial/temporal changes in contaminant distributions. Knowledge generated will assist making decisions locally and overseas regarding the protection of valuable living resources, the future environmental status of estuarine systems under alternative management and remedial strategies, management contaminated sediments, new legislation for best management practise, and support for long-term policy development for this estuary type.
