Using zircon crystals, researchers have discovered the route of a massive ancient river that could help find new reservoirs of fossil fuels and suggest how modern rivers might change over time.
More than two thirds of the worlds’ major cities are located in coastal deltas. How they change over time can impact communities that live around them.

And, they are also developing a new range of aquatic critter-containing sensors.
The Autonomous Live Animal Response Monitors (ALARM) will house live molluscs, insects or shrimps and transmit images and data to scientists via the web, in the ultimate test of a creek’s health. Continue reading Live streaming for healthy waterways
Australian Rivers Institute’s Assoc. Prof. Peter Pollard has researched rainforest lakes and rivers to test a provocative theory. The respiration of bacteria living and ‘breathing’ in these freshwater ecosystems is a major pathway for the return of rainforest carbon back to the atmosphere as the greenhouse gas carbon dioxide.

The health of southeast Queensland’s rivers, creeks and catchment areas are under scrutiny with the release of the 2009 Ecosystem Health Report Card.
Indigenous people value rivers in many ways. Rivers provide bush foods and medicines, they are part of a culturally significant landscape, and have the potential to sustain future water-related businesses and employment.
So it’s important to know what impact changing river flow patterns and water allocations could have on Indigenous communities.

Kilometre-wide erosion gullies eating their way across Australia’s northern landscape are proving likely culprits as the main source of the sediments that are flushed into the Gulf of Carpentaria each year, possibly smothering prawn and barramundi breeding and rearing habitats.
