How data is transforming the way we care for the ocean There is now overwhelming evidence that the future economic and ecological prosperity of the planet depends on a healthy ocean. At the same time, the science is clear that we have pushed our planet, and especially the ocean, to the point where its ability to provide the sustainable resources and value that people need is in danger. Happily, the last year has seen unprecedented commitments from governments, businesses, the United Nations and others to address these problems. The UN has proclaimed 2021-2030 as the Decade of Ocean Science for Sustainable Development to ensure that we have the knowledge we need to repair and restore the economic productivity of the ocean. Fourteen countries have joined together in a High Level Panel to find new solutions for a sustainable blue economy. In December, the 14 world leaders that comprise the High Level Panel for a Sustainable Ocean Economy put forward a new ocean action agenda underpinned by sustainably managing 100% of national waters, ensuring the health and wealth of our ocean for future generations. The transformative agenda cited harnessing ocean science, technology and data as a key priority, calling for action to promote transparent and open sharing and accessibility of ocean data.
