Yes, the Five Deeps Expedition has successfully conducted the first detailed, sonar mapping and sample-collection mission at the deepest part of the Diamantina Fracture Zone of the Indian Ocean – an area known as the Dordrecht Deep. Using advanced multi-beam sonar and an ultra-deep-sea lander, the team found it to be 7,019 meters deep, slightly shallower than previously thought when historically measured by other, less precise, methods.
The data will be an important contribution to the Nippon Foundation – GEBCO – Seabed 2030 Project to map the world’s seafloor in detail by the end of the year 2030.
