fish pens on the ocean

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.

CSIRO’s efforts to help the Australian farmed prawn industry recover from this devastating outbreak also required a rapid response to protect a vital research facility that is assisting the industry pick itself back 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.

As work gathers pace for the Intergovernmental Panel on Climate Change’s next climate predictions, scientists sense a groundswell of change to try and meet the Paris Agreement.

Diversity is a buzzword for the nation but when it comes to biodiversity studies done in the past decade, it turns out research has been rather one-sided.

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.
