We are pleased to announce that our programme Ocean Practices for the Decade is one of 60 new programmes and contributions endorsed under the UN Ocean Decade for transformative Decade Actions. The Ocean Practices for the Decade Programme (“OceanPractices’’) will support all ocean stakeholders in securing, equitably sharing, and collectively advancing this methodological heritage. By engaging diverse communities of practice and interlinking them through FAIR digital technologies, OceanPractices will transform how science and other stakeholders align their interests/capacities, creating ever-better practices, promoting sustainable human and ocean well-being. These practices improve interoperability and facilitate training so broader global participation naturally evolves. This programme will address many of the 14 recommendations put forward in our recent paper.
