A Chinese deep-ocean drilling ship has returned with what state-linked reporting calls 'precious' geological samples from the South China Sea. The cores are expected to help scientists study the seabed's structure and geological history, and underscore China's growing capability in deep-sea exploration. The mission also carries strategic weight, given competing territorial claims over the disputed waterway and interest in its seabed resources.

China has pushed its deep-sea drilling capability to the 5,000-meter level, becoming only the third country in the world to retrieve hard-rock samples from deep-ocean seabeds. The advance, reported by state media, underlines Beijing's push into deep-sea exploration technology, an area dominated by a small number of nations and increasingly tied to scientific prestige and potential seabed resources.

Environmental experts are warning that plastic pollution in the deep ocean may be interfering with the bioluminescent organisms that live there. Pollution particles could block or mimic the light signals deep sea species rely on for feeding, mating and defence, potentially disrupting entire ecosystems in one of the planet's least explored environments.

Scientists and commercial fishermen in the United States are calling on federal agencies to continue funding a deep-ocean observation system that monitors conditions far below the surface. The system provides data used for research and fishing operations, and supporters warn that cutting funding would leave a gap in understanding of deep-sea conditions and their effects on marine life and coastal economies.

Chinese state media report that the country's deep-sea drilling capability has reached the 5,000-meter level, marking a significant advance in its capacity to explore and extract resources from the ocean floor. The announcement highlights China's growing technological ambitions in deep-sea exploration and its push to secure strategic minerals and energy resources beneath the seabed.

China says it has completed a drilling operation reaching 16,172 feet, recovering hard rock core from deep beneath the ocean floor. If confirmed, the achievement would mark a significant advance in deep-sea drilling capability, with implications for geological research and seabed resource exploration. Details about the vessel, location and independent verification of the depth and recovery have not been reported.

Scientists report the discovery of a so-called "fire amoeba", an organism said to survive at temperatures beyond what was thought to be life's upper limit. If confirmed, the find would force a rethink of the thermal boundaries of life on Earth, with implications for the search for life in extreme environments such as deep-sea vents and possibly other planets.

Scientists conducting deep-sea research have discovered an unexpected creature living around 3,000 feet beneath the ocean's surface. One of the researchers described the sighting as shocking, suggesting the animal was found well outside its known habitat or depth range. The finding is drawing attention from marine biology enthusiasts and highlights how little is still known about life in the deep ocean.

China's Mengxiang, the country's deep-sea drilling vessel, has achieved a series of milestones during its voyage in the South China Sea, according to China Daily. The achievements mark progress for the ship, which is designed to drill deeper into the ocean floor than any previous vessel. The development highlights China's growing capabilities in deep-sea exploration technology.

Researchers have found that bacteria living on the gills of coral reef fish carry genes for chemosynthesis, the process of making food from chemicals rather than sunlight. DNA analysis revealed these genetic pathways in the gill microbes, suggesting reef fish may host bacteria capable of producing nutrients in ways previously associated with deep-sea ecosystems rather than sunlit reefs.

Wildlife cinematographer Richard Sidey has filmed footage of an iceberg calving off Ilulissat, Greenland, showing giant slabs of blue ice breaking apart and collapsing into the sea. The collapse triggers fractures that send waves rippling across the surrounding water, with deep creaks and rumbles captured at dawn. The footage is being shared widely, drawing attention to the raw power and sound of glacial ice as it breaks apart.

A newly reported scientific effort is shedding light on the ocean's 'deep reefs' — little-known coral and rocky ecosystems lying in dim waters beyond the reach of typical diving surveys. Researchers are using advanced exploration methods to document what lives there and how these hidden habitats function, as interest grows in protecting deep-sea environments.

Oceanographer Dawn Wright has given an interview with Yale School of the Environment about mapping the deep ocean, discussing efforts to chart the seabed and what remains unknown about the abyss. The conversation highlights the scale of unmapped ocean floor and why completing this work matters for science and policy.
