Using technology to better understand our Antarctic marine life

How do you measure data in such a large area for two species in a short amount of time? A team of scientists have used innovative technology to uncover the distribution of endangered blue whales and krill.

The thrill of the krill: giant super-organisms captured in 3D

Scientists on board our research vessel Investigator have 3D-modelled hundreds of millions of krill in giant swarm and noticed a puzzling gender imbalance.

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!

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.

‘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.

Explainer: how the Antarctic Circumpolar Current helps keep Antarctica frozen

The Antarctic Circumpolar Current, or ACC, is the strongest ocean current on our planet and is vital for Earth’s health because it keeps Antarctica cool and frozen.
