New technique tests for bacteria in dolphins’ breath
Until now it has been difficult to test the health of dolphin populations due to their migratory pattens, their size and, in some cases, dwindling numbers.
Researchers from the University of New South Wales have found an easy, fast and non-evasive way to give dolphins a quick health check, which in turn tells us much about the state of our oceans.
Australia and Japan are both island nations with vast maritime reserves and responsibilities. Together we’re developing the science needed to understand, use, enjoy and protect our unique marine ecosystems. And we’re collaborating to solve some of the mysteries of the ocean systems that drive the world’s climate.
Attack of the giant starfish
The waters off Japan’s tropical Okinawa Islands are home to hundreds of species of coral. The reefs attract a rich diversity of life: fish, turtles, whale sharks, and… the crown-of-thorns starfish.
Five thousand kilometres to the south is the Great Barrier Reef—the world’s largest reef system and one of the richest and most diverse natural ecosystems on Earth. The Australian Government is committed to protecting the Reef and has developed a plan to 2050 to ensure the sustainability of the Reef. But the Reef has lost half its coral cover in the past 30 years and periodic plagues of crown-of-thorns are responsible for more than forty per cent of the coral loss.

Coral trout in protected zones are not only bigger and more abundant than those in fished zones of the Great Barrier Reef Marine Park, they are also better able to cope with cyclone damage.
The oceans around East Antarctica are becoming acidic at a faster rate than expected, and could become toxic to some forms of marine life in the next 15 years.
The Reef Life Survey team has harnessed the efforts of 200 divers around the planet to create a unique global dataset that’s generating significant scientific findings.
More than 50 different environmental measures routinely collected by Australia’s national ocean research vessels—including sea surface temperature, dissolved oxygen concentration, and salinity—can now be accessed online almost as they are recorded.
The data is incorporated, often automatically, into predictive meteorological and ocean models, improving their accuracy. “So we end up with an improved representation not only of the weather but of processes like large scale ocean circulation or the state of the seas during tropical cyclones,” says Dr Roger Proctor, director of the e-Marine Information Infrastructure Facility of Australia’s Integrated Marine Observing System.
Water sampling devices are keeping watch around the clock for toxic discharges into Melbourne’s creeks and stormwater drains, thanks to Victorian researchers at the Centre for Aquatic Pollution Identification and Management (CAPIM), based at the University of Melbourne.
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→
Dr Tracy Ainsworth’s research is changing our understanding of the tiny coral animals that built Australia’s iconic Great Barrier Reef. Tracy and her colleagues at James Cook University in Townsville have found that the process of coral bleaching is a far more complex than previously thought, and begins at temperatures lower than previously considered. And she’s done so by applying skills in modern cell biology which she picked up working in neuroscience laboratories.
Her achievements won her a $20,000 L’Oréal Australia For Women in Science Fellowship in 2011, which she is using to study the low light, deep water reefs that underlie tropical surface reefs at depths of 100 metres or more. Continue reading The complex life of coral→
