'Dragon' and 'tree of life' hydrothermal vents discovered in Arctic region scientists thought was geologically dead
By Harry Baker published
Researchers have discovered a deep-sea hydrothermal vent field near Svalbard in an area previously assumed to be geologically inactive. The newfound vents have been named after various entities from Norse mythology.

Hot Tub of Despair: The deadly ocean pool that traps and pickles creatures that fall in
By Sascha Pare published
This stagnant brine pool at the bottom of the Gulf of Mexico is so toxic it kills and embalms any crabs and amphipods that are unlucky enough to stumble into it.

Earth from space: Shapeshifting rusty river winds through Madagascar's 'red lands'
By Harry Baker published
This 2018 astronaut photo shows the rust-colored waters of Madagascar's Betsiboka River winding through a complex series of mangrove islands. Both the river and islands have been altered in recent years by destructive human practices.

Earth from space: Ethereal algal vortex blooms at the heart of massive Baltic 'dead zone'
By Harry Baker published
In 2018, satellite images captured a stunning spiral of cyanobacteria blooming in the Baltic Sea. The swirling mass of microbes helped to create a massive "dead zone" the size of West Virginia that starved the surrounding water of oxygen.

Alaska's rivers are turning bright orange and as acidic as vinegar as toxic metal escapes from melting permafrost
By Harry Baker published
Alaska's melting permafrost is dumping toxic metals into the state's rivers, turning them bright orange and making the water highly acidic. The contaminated rivers are so vibrant they can be seen from space, and the problem is likely to get much worse in the future.

The Gulf Stream stopped pumping nutrients during the last ice age — and the same could be happening now
By Sascha Pare published
Atlantic currents slowed dramatically during the Younger Dryas period. By reconstructing those ancient ocean conditions, scientists think they can forecast changes over the next century.

Sleeping subduction zone could awaken and form a new 'Ring of Fire' that swallows the Atlantic Ocean
By Sascha Pare published
A modeling study suggests a slumbering subduction zone below the Gibraltar Strait is active and could break into the Atlantic Ocean in 20 million years' time, giving birth to an Atlantic "Ring of Fire."

Every 2.4 million years, Mars tugs on Earth so hard it changes the ocean floor
By Emily Cooke published
A new geological study suggests that Mars' gravitational field pulls the Earth closer to the sun over cycles lasting millions of years, warming our climate.

'More unzipping of the landscape': Arctic permafrost could crumble into rivers, unleashing devastating feedback loop
By Elyse Hauser published
Permafrost thaw could result in new rivers forming across the Arctic, potentially unleashing 35 million car journeys' worth of carbon every year.
