VICTORIA, Seychelles — The latest OceanX expedition, conducted in collaboration with the Ministry of Agriculture, Climate Change and Environment, achieved the deepest dive ever recorded in Seychelles waters, reaching depths of up to 4,600 metres in submersibles. Three major breakthroughs occurred during the deep-sea research exploration in the outer islands. Nineteen Seychellois researchers led the scientific objectives of the expedition and conducted the historic dive.
The second major accomplishment was a historic dive in the Amirantes trench, with a remotely operated vehicle reaching depths of 4,000 metres and marking the deepest dive in Seychelles’ history. The third breakthrough involved 3D mapping and deep-sea exploration of Aldabra and Assumption Islands, contributing to mapping 4,000 square kilometres within the country’s exclusive economic zone. The data gathered is expected to support long-term research on seamounts and marine biodiversity in the zone.
Mattie Rodrigue, science programme director for OceanX, highlighted the achievements during a visit to local media on board the vessel docked in Port Victoria. The collaboration is part of a long-running programme that pairs international science teams with local researchers. Officials said the joint work also gives Seychellois scientists hands-on experience with the latest deep-sea technology.
The expedition also recorded a full picture of how the ocean is with different types of sea creatures in the zone, including species that have not yet been described. Researchers said the footage and samples will be analysed in the coming months. The findings are expected to feed into ongoing discussions on how best to protect deep-sea habitats.
Officials from the Ministry of Agriculture, Climate Change and Environment said the results of the expedition will inform the country’s blue economy strategy, particularly the management of the outer islands. The data will also be shared with regional and international research partners. Both sides described the collaboration as a model for future joint expeditions.
