Researchers at KAUST have confirmed that the Red Sea once vanished entirely, turning into a barren salt desert before being suddenly flooded by waters from the Indian Ocean. The flood carved deep channels and restored marine life in less than ...
Marine heatwaves can jam the ocean’s natural carbon conveyor belt, preventing carbon from reaching the deep sea. Researchers studying two major heatwaves in the Gulf of Alaska found that plankton shifts caused carbon to build up near the surface ...
New research reveals that deep-sea mining could dramatically threaten 30 species of sharks, rays, and ghost sharks whose habitats overlap with proposed mining zones. Many of these species, already at risk of extinction, could face increased dangers ...
Swiss glaciers lost nearly 3% of their volume in 2025, following a snow-poor winter and scorching summer heatwaves. The melt has been so extreme that some glaciers lost more than two meters of ice thickness in a single season. Scientists caution ...
Scientists have uncovered an unexpected witness to Earth’s distant past: tiny iron oxide stones called ooids. These mineral snowballs lock away traces of ancient carbon, revealing that oceans between 1,000 and 541 million years ago held far less ...
Researchers found that ice can trigger stronger chemical reactions than liquid water, dissolving iron minerals in extreme cold. Freeze-thaw cycles amplify the effect, releasing iron into rivers and soils. With climate change accelerating these ...
The Dead Sea isn’t just the saltiest body of water on Earth—it’s a living laboratory for the formation of giant underground salt deposits. Researchers are unraveling how evaporation, temperature shifts, and unusual mixing patterns lead to ...
Hidden within Arctic ice, diatoms are proving to be anything but dormant. New Stanford research shows these glass-walled algae glide through frozen channels at record-breaking subzero temperatures, powered by mucus-like ropes and molecular motors. ...
Barrels dumped off Southern California decades ago have been found leaking alkaline waste, not just DDT, leaving behind eerie white halos and transforming parts of the seafloor into toxic vents. The findings reveal a persistent and little-known ...
Tiny ocean microbes called Prochlorococcus, once thought to be climate survivors, may struggle as seas warm. These cyanobacteria drive 5% of Earth’s photosynthesis and underpin much of the marine food web. A decade of research shows they thrive ...
New research has revealed that East Antarctica’s vast and icy interior is heating up faster than its coasts, fueled by warm air carried from the Southern Indian Ocean. Using 30 years of weather station data, scientists uncovered a hidden climate ...
Cambridge scientists discovered that thin, weak zones in Earth’s plates helped spread Iceland’s mantle plume across the North Atlantic, explaining why volcanic activity once spanned thousands of kilometers. These ancient scars not only shaped ...

Between 2003 and 2021, Earth saw a net boost in photosynthesis, mainly thanks to land plants thriving in warming, wetter conditions—especially in temperate and high-latitude regions. Meanwhile, ...

Mesopelagic fish, long overlooked in ocean chemistry, are now proven to excrete carbonate minerals much like their shallow-water counterparts—despite living in dark, high-pressure depths. Using the ...

For over two decades, satellites have quietly documented a major crisis unfolding beneath our feet: Earth's continents are drying out at unprecedented rates. Fueled by climate change, ...

Deep beneath the ocean's surface, a groundbreaking DNA study reveals that the deep sea is far more globally connected than once thought. By analyzing thousands of brittle stars preserved in ...

A new eco-friendly plastic called LAHB has shown it can biodegrade even in the extreme environment of the deep ocean, unlike conventional plastics that persist for decades. In real-world underwater ...

Over 300 million years ago, Illinois teemed with life in tropical swamps and seas, now preserved at the famous Mazon Creek fossil site. Researchers from the University of Missouri and geologist ...

Deep beneath the Antarctic seas lies a hidden network of 332 colossal submarine canyons, some plunging over 4,000 meters, revealed in unprecedented detail by new high-resolution mapping. These ...

Scientists in Svalbard were shocked to find rain and greenery instead of snow during Arctic winter fieldwork. The event highlights not just warming—but a full seasonal shift with major consequences ...

A scorching marine heatwave from 2014 to 2016 devastated the Pacific coast, shaking ecosystems from plankton to whales and triggering mass die-offs, migrations, and fishery collapses. Researchers ...

An ancient glacier high in the French Alps has revealed the oldest known ice in Western Europe—dating back over 12,000 years to the last Ice Age. This frozen archive, meticulously analyzed by ...

Hawaiian coral reefs may face unprecedented ocean acidification within 30 years, driven by carbon emissions. A new study by University of Hawai‘i researchers shows that even under conservative ...

Twenty-five years after first warning that oil spills would wane while invasive species and climate impacts would surge, an international team revisits its coastal forecasts and finds many ...

Ancient river landscapes buried beneath the East Antarctic Ice Sheet have been uncovered by radar, revealing vast, flat surfaces formed over 80 million years ago before Antarctica froze. These hidden ...

A laser-equipped research platform has, for the first time, photographed airflow just millimeters above ocean waves, revealing two simultaneous wind–wave energy-transfer tricks—slow short waves ...

As glaciers melt around the world, long-dormant volcanoes may be waking up beneath the ice. New research reveals that massive ice sheets have suppressed eruptions for thousands of years, building up ...

For decades, scientists believed the Arctic Ocean was sealed under a massive slab of ice during the coldest ice ages — but new research proves otherwise. Sediment samples from the seafloor, paired ...
