Since soon after our planet formed, Earth's 4.6 billion-year-long history was dominated by single-celled life. Something dramatic happened about 500 million years ago called the Cambrian "explosion," during which an incredible diversity of life forms became...
A mystery beginning in the South Atlantic and ending in South Kensington has finally been solved. The century-long story of two blue whale vertebrae can now be told for the first time, revealing their part in...

Treasures beneath the ocean floor? Seawater plays role in gold formation

Understanding how gold forms is crucial for knowing where to find it and how to extract it sustainably. McGill researchers have answered a long-standing...

Sediments reveal the ancient ocean during a mass extinction event

About 183 million years ago, volcanic activity in modern South Africa unleashed an estimated 20,500 gigatons of carbon dioxide (CO2) into the ocean–atmosphere system...

New discovery reveals that ocean algae unexpectedly help cool the Earth

A common type of ocean algae plays a significant role in producing a massively abundant compound that helps cool the Earth's climate, new research...

Ocean sponges suggest Earth has warmed longer, more than thought; some scientists dubious

A handful of centuries-old sponges from deep in the Caribbean are causing some scientists to think human-caused climate change began sooner and has heated...

New planet discovered has a massive ocean and it’s not too far from Earth

The scientific community has discovered a new planet. It is located 245 light-years away from Earth and has been named TOI-733b. Its size is...

Atlantic Ocean near Bermuda is warmer and more acidic than ever, 40 years of observation show

Decade-long ocean warming that impacts ocean circulation, a decrease in oxygen levels that contributes to changes in salinification and nutrient supply, and ocean acidification...

The ocean’s first large swimming apex predators had exceptionally rapid growth, fossil study finds

The rapid diversification of animals over 500 million years ago—often referred to as the Cambrian Explosion—saw the appearance of the first large swimming predators...

Volcanic eruptions found to dampen Indian Ocean El Niño events for up to 8 years

Volcanic eruptions occurring in tropical regions (23°N/S of the equator) have been linked to abrupt disruption of global-scale climate cycles in the Indian Ocean...

Hidden ocean the source of carbon dioxide on Jupiter moon: Research

Carbon dioxide detected on Jupiter's moon Europa comes from the vast ocean beneath its icy shell, research using James Webb Space Telescope data indicated...

Are deep blue seas fading? Oceans turn to new hue across parts of Earth, study finds

A large swath of Earth's oceans changed color over the past 20 years—and human activity is suspected to have caused it, a new study...

World’s oceans set new surface temperature record: EU monitor

The world's oceans set a new temperature record this week, raising concerns about knock-on effects on the planet's climate, marine life and coastal communities. The...

Dangerous slowing of Antarctic ocean circulation sooner than expected

Scientists have said that an acceleration of melting Antarctic ice and rising temperatures, driven by the emission of planet-warming gases, is expected to have...
