New research explains how ocean spray from Saturn's moon Enceladus turns into chemically diverse ice grains. Scientists studying material erupting from the moon's subsurface ocean describe the processes that give the ejected grains their varied chemical makeup, offering clues about the ocean's composition and its potential habitability. The findings shed light on one of the most intriguing ocean worlds in the solar system.

New research indicates that Earth microorganisms can survive in laboratory conditions mimicking the ocean of Enceladus, Saturn's icy moon. The findings suggest life could potentially endure in the subsurface sea beneath the moon's icy shell, strengthening the case for future missions to search for biosignatures there. Scientists say the result informs how experiments on the upcoming Enceladus missions might detect signs of life.

Scientists and commercial fishermen in New England are calling on federal agencies to maintain funding for a deep-ocean observation system that tracks conditions in Atlantic waters. Researchers use the system to study ocean changes, while fishermen rely on its data for safety and understanding fish stocks. The two groups, often at odds, are jointly pressing for continued federal support.

Under pressure from Congress, a network of ocean monitoring instruments that the Trump administration moved to shut down is being restored, according to the New York Times. The network supplies vital data used by meteorologists, climate scientists, oceanographers and the fishing industry, and its reversal follows a public outcry over the planned cuts.

A giant oceanic Kelvin wave is travelling across the Pacific and is expected to raise sea levels by around 30 centimetres along the American west coast, according to TF1 Info. The phenomenon, a powerful underwater wave moving along the equator, is often linked to El Niño events and can influence ocean temperatures and weather patterns, prompting attention from scientists and the public.

Climate researchers, including those speaking with CBS News Bay Area, are explaining how a Kelvin Wave affects ocean waters. A Kelvin Wave is a pulse of warm water that travels along the equator, and such waves can raise sea surface temperatures and influence weather patterns. Scientists are using the phenomenon to help the public understand how shifting ocean heat can shape climate conditions.

Scientists warn that the system of ocean currents often described as a giant conveyor belt, which circulates warm and cold water around the planet, is slowing down. If the circulation were to collapse entirely, the consequences could be felt worldwide, disrupting weather patterns, sea levels and marine ecosystems. Coverage is highlighting what a shutdown would mean for the global climate.

Scientists have retrieved experimental structures placed roughly 100 metres underwater ten years ago, concluding a decade-long study of the ocean's mysterious deep reefs. The recovered materials are expected to reveal how life develops and survives on mesophotic reefs, ecosystems far below where divers normally work and poorly understood compared with shallow coral reefs.

Scientists have identified a subtle new signal of climate change: shifting atmospheric dynamics linked to global warming are measurably slowing the Earth's rotation. As warming redistributes mass in the atmosphere and oceans, it alters the planet's angular momentum, lengthening days by tiny fractions of a second. The finding, reported by Phys.org, adds to evidence that human-driven climate change affects even fundamental planetary processes, and researchers say it could matter for precise timekeeping systems.

Marine biologists have identified a previously unknown species of plankton in waters off the Oregon coast. The find adds to knowledge of microscopic marine life in the Pacific Northwest, an area regularly surveyed by ocean researchers. Details about the organism and its ecological role are expected as scientists publish their findings.

A deep-sea camera at roughly 2,000 feet captured footage of a great white shark apparently concealing itself from something nearby, an unusual observation for a species normally tracked near the surface or along coastlines. The recording is drawing attention because it suggests great whites may retreat to the deep ocean to avoid predators or other threats, a behavior scientists have rarely documented.

The Monterey Bay Aquarium Research Institute says it will share its latest ocean research and technology at the OCEANS 2026 conference in Monterey. The institute, known for deep-sea robotics and exploration, regularly presents new tools and findings at the event, which gathers marine scientists and engineers. Further details about its presentations have not yet been announced.

A research expedition reports that current climate models misrepresent key processes in the Southern Ocean, the vast circumpolar waters that absorb much of the world's excess heat and carbon. The findings suggest projections of ocean heat uptake and climate change may carry significant errors. Scientists say better observations are needed to correct the models.

Researchers have identified a sea spider covered in hair-like legs and equipped with unusual mouthparts, described in striking terms in new coverage. Sea spiders are marine arthropods found in oceans worldwide, and discoveries of new species or anatomical details continue to fascinate scientists. The vivid description of its mouth has drawn attention to the strange anatomy of these deep-sea creatures.

Coverage is examining how ocean conditions expected during the 2026 Atlantic hurricane season affect coral reef ecosystems. The reporting focuses on the relationship between storm activity, sea temperatures and reef health, an issue of concern for coastal communities and marine scientists as the next hurricane season approaches.

Scientists are revisiting the question of whether life could exist on Enceladus, Saturn's icy moon. Beneath its thick ice crust lies a global ocean, where hot water is thought to react with the rocky core at the sea floor. A study last year revealed a surprisingly diverse range of organic molecules in that environment, fuelling speculation about habitability.

A new study published in AGU's journal suggests oxygen-deprived underwater zones, often called 'dead zones', may not be biologically barren. Instead, researchers argue these low-oxygen environments could offer clues about conditions on the early Earth, where life emerged before oxygen became abundant. The finding is drawing interest for reframing how scientists understand both modern ocean dead zones and the origins of life.

Scientists have described a new species of dragonfish, Eustomias clarkei, found in waters off the United States. The formal description was published in the journal Zootaxa, and the species' taxonomic treatment has been made openly accessible through Plazi's treatment repository. The announcement has drawn attention in science communication circles, where new deep-sea species discoveries typically generate interest due to how little is known about life in the ocean's depths.
