- 1Diver hovers motionless at reef edge to observe sea life●Check out this 8-sec video. I did something different on this morning’s dive. I dove out to the edge of the reef and the
A diver filmed an eight-second video of a different approach on a morning dive: swimming to the edge of the reef and hovering nearly motionless close to the seafloor for about 45 minutes. He says the local sea creatures gradually got used to his presence, offering an unusually close look at underwater life.

NOAA and partner organizations are conducting a deep-sea mapping expedition in waters near the Northern Mariana Islands in the western Pacific. The effort aims to chart previously unexplored seafloor terrain and document marine habitats in one of the ocean's least studied regions. It forms part of ongoing federal and international initiatives to complete seabed mapping and support ocean science and conservation.
- 3Thales and Arkeocean Team Up on Robotic Mine Countermeasures●Thales and Arkeocean Partner to Develop Robotic Mine Countermeasure Solution for Naval Forces As the threat from seafloo
Thales and Arkeocean have announced a partnership to develop a robotic mine countermeasure solution for naval forces. As the threat from seafloor mines grows, navies are seeking agile, lightweight systems that can adapt to different operational environments. The collaboration combines Thales's defense expertise with Arkeocean's underwater robotics technology, and defense observers are watching how the new system could reshape mine-hunting capabilities at sea.

NOAA Ocean Exploration has completed a deep-sea mapping project covering the exclusive economic zones of the Commonwealth of the Northern Mariana Islands and Guam. The survey work maps previously poorly charted seafloor areas in the western Pacific, providing data that can support ocean management, navigation safety, hazard assessment and future scientific research in the region.
- 5Deep-Sea Mining Scars Still Visible After 40 Years, Study Finds▼SMARTEX Study Finds Deep-Sea Mining Scars Linger 40+ Years On
A study from the SMARTEX research project has found that marks left by experimental deep-sea mining on the seabed remain more than 40 years later, suggesting seafloor ecosystems recover far more slowly than hoped. The findings are being cited in ongoing debates over whether commercial mining of the deep ocean should be allowed to proceed.
- 6Deep-sea mining scars still visible 44 years on●Impact of deep-sea mining on seafloor ecosystem still evident 44 years later https:// lemmy.zip/post/74398715
A new study finds that tracks left by a 1979 deep-sea mining test in the Pacific Ocean remain clearly visible on the seafloor more than four decades later, showing that damage to abyssal ecosystems can persist far longer than expected. Researchers say the findings raise fresh concerns as countries and companies push to begin commercial mining of polymetallic nodules, which support slow-recovering marine life.
- 7Night diver films ambush predator on Indonesian seafloor▼Night diver films ambush predator slithering over the seafloor in Indonesia
A night diver in Indonesia filmed an ambush predator gliding across the seafloor, with the footage shared by BBC Wildlife Magazine. The clip shows the animal's stealthy hunting behaviour, characteristic of species that lie in wait for prey on sandy or muddy bottoms after dark. It is drawing attention for offering a rare close-up look at nocturnal marine life rarely seen by divers.

Chinese research ships spend more time loitering near undersea cables in the Pacific than vessels of any other nation, according to a new report. The civilian fleet has reportedly been tracked performing 'lawnmower' survey patterns over critical cable routes, raising concerns that the ships may be mapping the seafloor in ways that could enable future sabotage of communications infrastructure.
