Kongsberg, Ocean Exploration Trust Launch Pacific Seabed Mapping Expedition
Exploration Trust (OET) have launched a seabed mapping expedition in the Central Pacific aimed at surveying previously unexplored areas of the ocean floor and testing next-generation mapping technology.The Pacific Mapping expedition, running from June 10 to June 24, will see OET's Exploration Vessel Nautilus deploy Kongsberg's EM 304 MKII multibeam echo sounder for the first time.Three Kongsberg engineers will be aboard the vessel throughout the 14-day mission, using the expedition as a platform to test and refine multibeam mapping technology under real-world operating conditions.The EM 304 MKII

what they see and learn.Data gathered during the expedition will be made publicly available and shared with the Cook Islands government to support the management of marine resources in the region.This work will build on a NOAA-funded 2025 expedition conducted in the Cook Islands on Exploration Vessel Nautilus with the Cook Islands Seabed Minerals Authority and the Ocean Exploration Cooperative Institute.The mission’s focus is on scientific exploration and environmental data collection in areas known to contain polymetallic nodules. NOAA’s partnership with the Cook Islands will allow a better
NOAA-Led Expedition Maps Cook Islands’ Exclusive Economic Zone
Exploration Vessel Nautilus, operated by the Ocean Exploration Trust, successfully completed a three-week mission to map and explore the Cook Islands’ Exclusive Economic Zone (EEZ). This collaborative effort, led by the National Oceanic and Atmospheric Administration (NOAA) through its Ocean Exploration program and supported by a grant to the Ocean Exploration Cooperative Institute (OECI), marks a milestone in strengthening U.S.-Cook Islands partnerships in marine resource management.Guided by priorities set by the Cook Islands Seabed Minerals Authority (SBMA), the expedition employed

TDI-Brooks Adds to Africa Project List with Nigerian Survey
working in Nigeria until the third quarter of this year on various analogue and 2D HR survey projects.TDI-Brooks is presently operating three vessels in West and Southwest Africa, engaged in various projects for leading international oil companies. The company’s 75-meter DP-II vessel, R/V Nautilus, is currently involved in a deepwater geotechnical project off the coast of Namibia, which includes 20-meter JPCs and 40-meter CPT-Stingers.Following this, the company will undertake a shallow water deep push CPT project with its Manta-200. These projects are expected to conclude by early March
Ocean Exploration taps Leeway Marine to Manage Ship
The Ocean Exploration Trust (OET) has selected LeeWay Marine to step into the vital role of vessel manager.LeeWay will be responsible for crewing the vessel and overseeing the technical support and operational planning required to complete the critical missions scheduled for their Exploration Vessel Nautilus (E/V Nautilus).Established by American oceanographer Dr. Robert Ballard, best known for discovering “black smoker” hydrothermal vents and the final resting place of R.M.S. Titanic, OET makes ocean exploration possible, providing hands-on and remote learning opportunities for scientists
UK Approves Five Subsea Power Cable Projects
into both British and European grids, and are both planned by National Grid.The LionLink project, co-owned by Dutch grid operator Tennet, will connect Dutch offshore wind farms to both the Dutch and the British grids and provide up to 1.8 GW of low-carbon electricity to each country.In the same way, the Nautilus project, co-owned with Belgian grid operator Elia, will connect Belgian offshore wind and provide up to 1.4 GW of capacity to each country.The new projects are all expected to be complete and operational by the end of 2032, Ofgem said.National Grid's participation in the OHA projects is conditional
TDI-Brooks Concludes Geotechnical Campaign Off Turkey
TDI-Brooks, a U.S.-based marine services company specializing in geotechnical and offshore survey projects, has completed its fifth geotechnical investigation for DenAr Ocean Engineering in Black SeaThe RV NAUTILUS was dispatched to the Black Sea from the US East Coast to facilitate this operation. The geotechnical aspect of the investigation included 49 gCPTs, 50 JPCs, 48 CPTs, and 41 BCs.Additionally, an environmental component was incorporated, which comprised 27 Environmental BCs, 28 CTDs, 19 water samples, and 180 kilometers of marine fauna transects.TDI-Brooks provides a comprehensive range of
