Continents slowly shed their deep roots during breakup, sending ancient mantle material beneath the oceans and creating enriched volcanic activity. Ocean volcanoes often erupt lavas with chemical signatures that seem too old and too enriched to come...

depressions and linear marks in ancient Italian sedimentary rocks that extend the record of vertebrate activity in the deep ocean by tens of millions of years. Radiometric dating places these traces at roughly 130 million years old, indicating that fish...

are unrealistically long, overly abundant, or both. Consequently, the authors conclude that direct exchange between the deep ocean and the near‑surface environment is likely limited. Upcoming Probes Must Pinpoint Origins of Near‑Surface Liquid These...

This affects how easily marine organisms produce calcium carbonate shells and how readily those shells dissolve in the deep ocean. Lower calcium reduces calcite saturation. This can decrease shell production and alter how carbon is stored in marine...

video, posted by the Schmidt Ocean Institute, provides an unprecedented window into the natural behavior of one of the deep ocean’s most mysterious inhabitants. Voir cette publication sur Instagram Magnapinna Biology: Size, Shape and Unanswered...

Scientists finally identify NOAA’s mysterious golden orb, uncovering a bizarre deep‑sea secret hidden beneath the waves. During a NOAA expedition on August 30 2023, the remotely operated vehicle Deep Discoverer illuminated a strange, dome‑shaped,...

Scientists exploring Brazil’s offshore waters discovered a hidden realm of bizarre, rarely‑seen marine species, revealing an unprecedented underwater world. An international research team spent two weeks exploring the Brazilian offshore waters,...

Scientists have identified three new species of chitons from deep and tropical oceans, including one found more than five kilometers down, whose name was chosen with help from the public. Far below the ocean’s surface, life continues quietly. There is...

New study reveals a nutrient‑starved microbial process that triggers a climate feedback loop overlooked by major forecasting models. For many years scientists observed that oxygen‑rich surface waters were emitting measurable amounts of methane, a gas...

New simulations reveal how giant impacts shaped icy moons and their hidden subsurface oceans over time, challenging our understanding of these frozen worlds. High-energy impacts in the outer reaches of the Solar System, once thought to be potential...

First underwater habitat opens its doors to human crews, revealing what life inside a deep‑sea living lab really feels like. A deep‑sea laboratory has been installed on the seafloor of the Florida Keys, turning a once‑science‑fiction concept into a...

Scientists have recreated the extreme alkaline conditions of Enceladus’s ocean, discovering how water-rock chemistry allows methane-producing microbes to thrive. The hidden, global ocean beneath the icy crust of Saturn’s moon Enceladus has long been a...

transport, the researchers suggest the giant sea spiders could serve as social hubs. In the vast, dark expanse of the deep ocean, finding a mate is notoriously difficult. By congregating on a mobile host, the amphipods—which included mixed-sex pairs in...

the team logged 29 distinct items of human-made refuse at depths reaching 3,820 meters. Signs of Human Impact in the Deep Ocean Submarine canyons serve as massive, natural conduits that channel nutrients and sediments toward the deep ocean, making them...

radioactive material. The fuel is corroding. And the structure of the submarine will not remain intact forever. In the deep ocean, change happens slowly. But it does happen. Continued Monitoring Is Essential Researchers emphasize that ongoing...

the specific, delicate configuration of the tar lilies was entirely unexpected. The discovery underscores how much of the deep ocean remains a mystery, even in regions subject to intense commercial energy exploration. The Chemistry of Deep-Sea Seepage...

Scientists filmed a sudden rift on the seafloor between Australia and Antarctica as magma surged upward, capturing the violent event in real time. In April 2024 a fissure opened on the seafloor between Australia and Antarctica, and for the first time...

appendages. The bigfin squid, scientifically classified as Magnapinna, dwells within the perpetual darkness of the deep ocean. It remains among the least understood of all cephalopods, with fewer than 70 individuals having been recorded or collected...

the Schmidt Ocean Institute, noted that these systems “provide heat and chemical energy that allow life to thrive in the deep ocean without sunlight, so a better understanding of these systems could provide clues for finding life on other planets.” One...

Decades of hidden Earth signals reveal Beneath the Pacific basin, a vast pocket of liquid iron altered its flow direction near 2010, hinting that Earth’s inner dynamics can undergo rapid shifts. The planet’s outer core, a massive layer of swirling...
