Ocean flows and productivity

New measurements from the ocean under the centre of the Ross Ice Shelf have significantly improved our understanding of the complex processes that drive melting in Antarctica.

Understanding how the Antarctic oceans work is vital to predicting the world’s future climate and the implications of climate change for humankind and the planet.

The new science season at Antarctica is just a few days away from opening and NIWA researchers are busy packing containers and shipping them to the ice where they will be reunited with them in the coming months.

The world’s oceans are acidifying as a result of the carbon dioxide (CO2) generated by humanity.
