The CAO Projects

The CAO programme started in February 2017 with four large projects (Arctic PRIZE, ARISE, ChAOS, DIAPOD) funded by NERC. A further 12 projects joined the programme in July 2018, co-funded by NERC and the German Federal Ministry of Education and Research. Each one investigates different aspects of the Changing Arctic Ocean. Combined, the projects involve 32 research institutions and organisations in the UK and Germany, and more than 200 scientists.

    New study uncovers hidden behaviour of the Arctic Ocean’s currents that could alter future climate change predictions

    Press release of 18th August 2021 from National Oceanography Centre A new study has discovered that the Transpolar Drift, a strong surface current in the Arctic Ocean, is more variable than was previously known. With the Arctic currently changing at unprecedented rates, this discovery could impact future predictions for climate…
