Oceans

Tiny hair-like appendages on corals generate swirling microscopic currents – an ingenious way to exchange oxygen and nutrients with their surroundings

A new technique is combining geochemistry and marine ecology to more accurately determine the age of sharks and reconstruct their life history

First it was sharks in Sydney, and now jellyfish are shutting beaches in Melbourne. But are jellyfish blooms becoming more frequent or is it just a natural cycle?

The ocean is fundamental to life on our planet and to our future. It’s time for leaders to listen to the evidence-based science and act

New research finds the more Antarctic ice melts, the more the ocean is flooded by melt water, the more the Antarctic Circumpolar Current is likely to slow down – creating a vicious climate change cycle

New modelling shows that as noise from shipping and other human activities surges, whales will find it increasingly harder to successfully migrate

Fleeting interactions between the smallest phytoplankton and bacteria help to shape global ocean productivity

Mathematical modelling reveals that human-driven noise in our oceans is affecting marine life, particularly whales, confusing their annual migrations

A new approach estimates the risks that fishing and climate change pose to any shark species here in Australia, and potentially worldwide

As the planet warms, researchers are warning that the frequency and magnitude of extreme wave events may rise by around 10 per cent by the end of century, increasing flood risks
