REV Ocean is a global not-for-profit organisation still being fully established after its launch in 2017 by Norwegian businessman and philanthropist Kjell Inge Røkke and marine biologist Nina Jensen. The initiative will launch the world’s largest, most advanced research and expedition ship. The vessel, which is scheduled to begin operation in late 2022 or early 2023, will be equipped with a full suite of sensors for mapping the seafloor and biological communities in the water column as well as profilers and start-of-the-art processing software. The ship will carry researchers and ocean enthusiasts from the business community, political circles and research institutions. Its objective will be to find concrete, scalable and commercially viable solutions for improving ocean health. It will focus on three primary areas where action is needed – plastic pollution; climate change and ocean acidiﬁcation; and overﬁshing and the environmental impacts of ﬁshing.
