State of the Environment report highlights pressures on our coasts and oceans

CSIRO researchers have again played a major role in the latest Australia State of the Environment report as lead authors on both the Marine and Coasts chapters. In a first, Indigenous knowledge and perspectives have been included, thanks to some of their work.

Helping fishers adapt to warming oceans

CSIRO research is helping Australian fisheries adapt to seas that are warming at a rate far greater than elsewhere around the globe.

Connectivity in scalloped hammerheads

Scalloped hammerheads occur in tropical and temperate oceans around the world, but are their populations connected? A new genetic study using whole genome methods has found out.

How our new technology improves oil spill response

Oil spills can cause significant environmental damage. We have developed new oil spill response technology that focuses on removing small oil droplets. And it all starts off with the humble domestic sponge ...

The International Space Station was orbiting above the Northern Territory of Australia when this photograph was taken of the Gulf of Carpentaria including (from bottom left to right) the Pellew Islands, Wellesley Islands and South Wellesley Islands. One of the station's main solar arrays drapes the left side of this photograph.

Monitoring our vast and varied coasts

Human advancement is testing the resilience of our coasts, from the molecular level to the planetary. CSIRO's technologies are helping manage our changing coasts.
