Scientists take a close look at what’s behind low-oxygen levels under salmon farms in Tasmania’s Macquarie Harbour.
They’re elusive, whale sharks, so we’re keeping an eye on them using satellite tracking to see how far they travel and, in a world first, taking DNA samples to see just how old they are. Here they are on Ningaloo reef.
Here’s one aspect of rising sea levels to think about – the loss in light reflected through ocean waters. Marine ecologists are asking, what are the limits, and threats, to coral skyscrapers? Because coral reefs don’t just spread out – they also spread up.
The Southern Ocean has an enormously influential role on the Earth’s climate, it reaches from the Antarctic into all the world’s oceans. What research now shows is local ocean processes have global impacts.
We’re dusting off old tide records, some dating back to the late 19th century, in a project to digitise these old hard-copy records so the data they contain can be used to analyse how extreme sea levels in Australia have changed over time.
A new field guide to the sharks and rays of Papua New Guinea is supporting sustainable use of its shark and ray resources.
Hundreds of southern bluefin tuna have been tagged to reveal more about their annual migration and feeding habits in the Great Australian Bight.
Dr Steve Rintoul is embarking on his 13th voyage to the Antarctic. On board the RV Investigator and armed with new deep water robots, he and his team will be probing the remaining unknowns of the Southern Ocean’s role in our climate system.
