Eavesdropping on Antarctic blue whales

A team of researchers from the Australian Antarctic Division on board the RV Investigator are using underwater listening devices originally developed to track submarines to find ‘hotspots’ of Antarctic blue whales.

Are tropical holidays bad for your evolution?

New research shows the history of our deep ocean is written in the stars.

Krill, whales and poo power

At the end of the day, who doesn’t like a good poo story (especially when it's about poo from the largest animal on Earth)!

Did a hotspot break up your relationship?

We’re back out on the waves on board RV Investigator serving up live science plucked fresh from the high seas – and what a voyage it’s been!

Love fish? Choose a range when selecting seafood.

Our research shows that huge economic and environmental benefits could come from fully using fish now discarded. If all of the edible fish caught was kept and sold, both the sustainability and profitability of fishing would significantly improve.

Exploring Australia’s ‘other reefs’ south of Tasmania

In the cold southern oceans, underwater mountains support deep-sea reefs.

Piping hot marine research delivered to your door

Four years of piping hot marine research delivered to your door is dropping knowledge bombs to change your world.

Cooee! Sound-testing 1200 metres beneath the waves

We're using an echolocator to watch the daily migration of sea life rise up from depths to feed at dusk and then return back to the depths at dawn. But some fish have oil-filled bladders rather than a gas bladder making their reflection weak and difficult to count. That's where our special camera comes in.

Here’s the seafood Australians eat (and what we should be eating)

Over 85 per cent of seafood caught in Australia is sustainable. However, just because a fish is sustainably caught, it doesn’t make it the most nutritious and healthy option – and vice versa. We've compared the two to see what seafood is both sustainable and nutritious.

‘Heartbreaking’ discovery of human trash 100km off Tasmanian coastline

Scientists discover birds toying with a party balloon and plastic bottle, with a soft drink can spotted 1,000 metres down on the ocean floor — sights described by researchers as "heartbreaking".

Eyes on the deep sea: the coral that thrives in the dark

We are surveying deep-sea coral reefs growing on underwater mountains to deepen our understanding of these extraordinary marine communities.

Nursing Grey Nurse Shark populations back to health

Grey Nurse Sharks are critically endangered in parts of Australia. Our research is helping to assist the conservation management of the species.
