Small fish swimming over kelp beds

Kelp forests along hundreds of kilometres of Western Australia's coastline were wiped out in 2011 and have not recovered.

The ocean stretching to the horizon

Our understanding of the ocean’s biological pump, and the capacity of the ocean to sequester carbon dioxide, has been enhanced by a new study examining ocean eddies.

Plants and animals all over the world are redistributing and changing their behaviour in response to warming temperatures. Observing these changes tells us a lot about our changing climate.

Queensland Coastline as seen from space shows the Great Barrier Reef and muddy water flowing from hte Burdekin River into the ocean.

The Great Barrier Reef is at risk from factors in and out of the water. Dr Christian Roth discusses what needs to change, and how, to save our reef.

Corals and ocean water on the Great Barrier Reef as seen from the air

New technology fitted into an aeroplane and flown over parts of the Great Barrier Reef will provide a more detailed survey of coral reef health than ever before and give a boost to global reef science.

Ocean acidification will hurt some parts of the Great Barrier Reef more than others.

An icy landscape mirrored in the water

Over the next decade, The Homeward Bound project will give 1000 female scientists the tools to become influential, global decision makers of the future. Its debut voyage will depart later this year, with four CSIRO scientists on board.

Close up of the head of a Yellow Fin Tuna

New molecular techniques have shown that the population dynamics of yellowfin tuna in the Pacific Ocean are not as we thought. Further application of these techniques may herald a more scientific approach to management of ocean fisheries, and help curb illegal fishing.

The white underside of a whale's pectoral fin emerging from the water

A new review of published research into the impacts of climate change on marine animals has provided a big picture view of how important biological processes are changing. Things like migration and breeding times are changing for some marine vertebrates, like whales, shorebirds, turtles and fish.
