Seabed 2030: Global Initiative Maps Over 25% of Ocean Floor, Revealing Hidden Underwater Landscapes

The Seabed 2030 project, launched in 2017, has mapped over 25% of the ocean floor, a significant increase from just 6%. This global initiative combines historical data, sonar technology from research and industry vessels, and advanced computing power to create detailed seabed maps. Vicki Ferrini from Columbia University highlights that these maps reveal intricate underwater features, enhancing our understanding of ocean processes. Multibeam sonar technology, which provides a 3D view of the seabed, is crucial for this effort. The project addresses challenges like data resolution variations and geopolitical complexities, especially in contested areas like the Arctic. Machine learning aids in data processing and imagery enhancement. Funded by the Nippon Foundation, Seabed 2030 aims to inform decisions on seabed mining and other critical issues by providing essential data.
