Oxygen is disappearing from oceans, lakes, rivers, and coastal waters at an alarming rate, threatening aquatic life and weakening the natural processes that help regulate Earth’s climate. Scientists warn that this widespread deoxygenation is ...
Scientists have found evidence that a major Cascadia earthquake could trigger a second quake on the San Andreas Fault. The discovery came from unusual sediment layers formed by underwater landslides ...
Seismic waves have revealed that the oceanic plate beneath the Ontong Java Plateau was dramatically transformed by the colossal volcanic activity that created it more than 100 million years ago. Researchers found a complex structure of horizontal ...
A major DNA study has rewritten the koala's evolutionary story, revealing that the species suffered a dramatic population collapse about 100,000 years ago, long before humans arrived in Australia. By calculating the koala's mutation rate for the ...
Scientists have identified a hidden feedback loop that may explain how Earth has regulated its climate for tens of millions of years. As sea levels rose and fell, they changed how much phosphate reached the open ocean, affecting marine life and the ...
NASA's PACE satellite captured the Black Sea glowing turquoise during its annual phytoplankton bloom. The vivid color comes from massive numbers of coccolithophores, microscopic organisms whose reflective shells brighten the water enough to be seen ...
Scientists discovered that extreme deep-sea pressure squeezes valuable nutrients out of sinking organic particles, providing an unexpected food source for ocean microbes. The finding could rewrite our understanding of both deep-ocean ecosystems and ...
Why do beaches today have seashells from clams and snails instead of brachiopods? A new study suggests the answer lies in Earth's greatest mass extinction, when warming oceans and falling oxygen levels wiped out animals that couldn't adapt. Species ...
A newly discovered underwater volcanic eruption north of Papua New Guinea is unfolding in one of the world's most poorly mapped ocean basins. Satellites have spotted steam plumes, ash, thermal hotspots, and huge floating pumice rafts, suggesting ...
Scientists have uncovered a hidden weakness beneath the Pacific Ocean that helps explain why Japan’s catastrophic 2011 earthquake and tsunami became so devastating. By drilling deeper into the ...
A new study found that not all geoengineering ideas are created equal. Brightening marine clouds over the eastern Pacific could dramatically weaken the El Niño cycle, triggering major changes to ...
A Pacific-wide tsunami triggered by a magnitude 8.8 Kamchatka earthquake gave scientists their first detailed satellite view of a major tsunami in motion. The observations revealed unexpected wave behavior and helped uncover a larger earthquake ...

Scientists have confirmed that a mysterious Utah earthquake first detected in 1979 really did occur nearly 90 kilometers underground—far deeper than anyone thought earthquakes could happen beneath ...

The Arctic Ocean may have crossed a dangerous tipping point. Scientists say the rapid disappearance of sea ice is triggering a hidden chemical shift that is stripping the ocean of nitrate — a ...

A new study suggests Antarctica’s ice sheet hit a climate tipping point about one million years ago, making it far more reactive to temperature and CO2 changes. Researchers warn this surprising ...

The world’s oceans are rising at an accelerating pace, and scientists now say they can fully explain what’s driving it. Warming seawater is the biggest factor, while melting glaciers and polar ...

A mysterious underwater fault near Ecuador has been producing nearly identical magnitude 6 earthquakes every five to six years, baffling scientists for decades. Researchers now believe the fault ...

Scientists have finally cracked the mystery behind one of climate change’s strangest fingerprints: while Earth’s surface heats up, the upper atmosphere is rapidly cooling. Researchers at Columbia ...

Scientists have uncovered a hidden Antarctic threat that could accelerate global sea level rise far faster than expected. Deep beneath floating ice shelves, long channels carved into the ice appear ...

Antarctica’s Hektoria Glacier collapsed with shocking speed, retreating 15 miles in only 15 months and setting a modern record for grounded ice loss. Scientists say warming conditions and ...

Scientists exploring deep underwater canyons off the coast of Western Australia uncovered a hidden world packed with bizarre and elusive marine life — including signs of the legendary giant squid. ...

Scientists have uncovered strong evidence that a major Atlantic Ocean current system tied to global climate is weakening. The slowdown has been detected across a vast region of the North Atlantic ...

Southern Alaska’s winter finale delivered a spectacular atmospheric display, captured by a NASA satellite. Cold Arctic air flowing over warmer ocean waters created long bands of clouds, swirling ...

Deep beneath the Southern Ocean, a quiet but alarming shift is underway: warm water is creeping closer to Antarctica, and scientists are now seeing it clearly for the first time. By combining decades ...

Deep beneath Portugal’s São Jorge Island, a massive surge of magma silently pushed upward from more than 20 kilometers underground in 2022, triggering thousands of earthquakes and briefly raising ...

Australia’s famous Twelve Apostles didn’t just erode into existence—they were slowly pushed up from the ocean floor by powerful tectonic forces over millions of years, new research reveals. ...

A mysterious “golden orb” found more than two miles deep in the Gulf of Alaska left scientists baffled for over two years, sparking wild speculation about its origins. After an intensive ...

A new study suggests Neanderthals didn’t go extinct simply because of climate change or competition with Homo sapiens. Instead, the key difference may have been social connectivity—Homo sapiens ...

A new AI-driven method called GOFLOW is turning weather satellite images into highly detailed maps of ocean currents. By tracking how temperature patterns shift over time, it can reveal fast-moving, ...

Gray whales are beginning to break their long-established migration patterns, venturing into risky new territory like San Francisco Bay as climate change disrupts their Arctic food supply. But this ...

A colossal ocean current encircling Antarctica—stronger than all the world’s rivers combined—played a far more complex role in shaping Earth’s climate than scientists once thought. New ...

Asteroid impacts may have helped kick-start life on Earth by creating hot, chemical-rich environments ideal for early biology. These impact-generated hydrothermal systems could have lasted thousands ...
