- 1China claims record 16,172-foot ocean drilling feat●China claims 16,172-foot drilling feat with ocean hard rock recovery
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.
- 2China's deep-sea drilling capacity reaches 5,000 meters●China's deep-sea drilling capacity reaches 5,000-meter level
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.
- 3Bottom Trawling and Deep-Sea Mining Share the Same Threat●What makes bottom trawling and proposed deep-sea mining twin horrors is that same fundamental mechanism: taking ecosyste
An argument gaining traction holds that bottom trawling and proposed deep-sea mining are 'twin horrors' because both exploit ecosystems that operate on geological timescales. Corals grow millimeters a year and ocean currents take centuries to settle sediment, so habitats destroyed by these activities may never recover on human timescales. The comparison is being used to press for stronger protection of the ocean floor before deep-sea mining moves forward.
- 4Millions of tyres dumped for artificial reef became an ocean disaster▼On a site the size of 27 football fields, 2 million of these were dropped in the ocean to create an artificial reef – instead, it became a disaster
Around two million tyres were dropped onto the seabed on a site the size of 27 football fields in an attempt to create an artificial reef. Instead of attracting marine life, the project became an environmental disaster, as the tyres failed to form a reef, scattered across the ocean floor, and leached toxins. The scheme is now widely cited as a cautionary tale about large-scale marine engineering projects.
- 5Meta quietly building 4,300-mile undersea internet cable●While Everyone’s Debating Muse, Mark Zuckerberg Is Quietly Building a 4,300-Mile Cable Under the Ocean. Here’s What It’s For.
While public attention stays on AI debates, Meta is moving forward with a massive subsea cable project stretching roughly 4,300 miles across the ocean floor. The infrastructure aims to carry enormous volumes of internet traffic between continents, giving Meta greater control over the pipes that carry its apps' data. Observers note the project underscores how tech giants now build core internet infrastructure themselves, rivaling traditional telecom consortiums.
- 6China's Mengxiang vessel hits milestones in South China Sea voyage▼China's Mengxiang vessel achieves milestones in South China Sea voyage
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.
- 7Scientists Say Millions of Ancient 'Batteries' Lie on the Ocean Floor▼Scientists Just Discovered Millions of Ancient ‘Batteries’ Hiding on the Bottom of the Ocean
Scientists report the discovery of millions of ancient 'battery'-like formations resting on the seabed, according to a report by Popular Mechanics. The find suggests these natural structures, likened to batteries, may have formed long ago on the ocean floor. Details about who made the discovery, where, and what the formations actually are remain limited in early coverage.
- 8Startup tests seafloor geothermal power for island grids▼Startup tests seafloor geothermal power for diesel-dependent island energy systems
A startup is testing geothermal energy systems placed on the seafloor, aiming to replace diesel generators that island communities rely on for electricity. The technology would tap heat beneath the ocean floor to provide steady renewable power where shipping fuel is costly. If proven, it could offer remote islands a cleaner, more secure alternative to imported diesel.
- 9Ocean Casino bets $14M on high-limit slot expansion▼Ocean Casino bets $14M on high-limit slot expansion after ownership change
Ocean Casino Resort in Atlantic City is investing $14 million to expand its high-limit slot offerings following a change in ownership. The project signals the new owners' intent to court higher-spending gamblers and sharpen the property's competitive position. The move comes as Atlantic City casinos continue reshaping their floor space and amenities to chase premium customers.
- 10Oceanographer Dawn Wright on Mapping the Deep Sea▼Mapping the Abyss: A Conversation with Oceanographer Dawn Wright
Oceanographer and geographer Dawn Wright has given an interview with Yale School of the Environment discussing efforts to map the ocean floor, often called mapping the abyss. Wright, known for her work in ocean science and previously as chief scientist at Esri, talks through the state of deep-sea exploration and why complete seafloor mapping remains a major scientific challenge. The conversation highlights how little of the ocean bottom has been charted in detail.
- 11NOAA highlights striking spiral shape of Iridogorgia corals▼Beautiful Characteristic Spiral of Iridogorgia Corals
NOAA Ocean Exploration is drawing attention to Iridogorgia corals, deep-sea creatures known for their distinctive spiral shape that stands out on the ocean floor. The agency shared images of the corals' characteristic twisted form, which can grow several feet tall in deep waters. Ocean enthusiasts and marine biology followers are admiring the unusual beauty of these rarely seen animals.
- 12Plastic fused to coral rubble raises new ocean pollution concerns▼Plastic fused to coral rubble raises new concerns for ocean pollution
Researchers have documented plastic debris becoming fused to coral rubble on the ocean floor, creating a new form of pollution that combines plastic waste with damaged reef material. The finding suggests plastic may be integrating into marine environments in ways that are harder to detect and remove than floating debris, compounding concerns about its long-term impact on coral reef ecosystems already stressed by warming waters.
- 13Deep-Sea 'Pools Of Death' May Hold Clues To Origins Of Life▼Ocean Floor “Pools Of Death” Could Be Key To Explaining The Origins Of Life On Earth, And Possibly Further Afield
Scientists are highlighting brine pools on the ocean floor — extremely salty underwater basins that kill most life that enters them — as potential keys to understanding how life began on Earth. The theory suggests similar chemical conditions in these pools may have driven the formation of early organic molecules, and that comparable environments could exist on other worlds, making them a target in the search for extraterrestrial life.
- 14Ocean floor found to strongly influence global climate▼Earth’s ocean floor has a surprisingly powerful effect on climate
New reporting highlights that Earth's ocean floor plays a far larger role in regulating the climate than previously understood. The seafloor influences how heat and carbon are stored and exchanged between the ocean and the atmosphere, processes that are central to climate models and projections. Coverage on multiple outlets is drawing attention to how much of the planet's climate machinery sits beneath the waves, largely out of sight.
- 15Conservationists sue Trump administration office over deep-sea mining●Conservationists take Trump office to court over deep-sea mining
Conservation groups have filed a lawsuit against an office within the Trump administration over its handling of deep-sea mining. The legal challenge targets the government's stance on extracting minerals from the ocean floor, an issue that has drawn growing opposition from scientists and environmental organisations concerned about damage to fragile marine ecosystems. Details of the claims and the office's response were not immediately available.
