Satellite data reveal nearly 20,000 previously unknown deep-sea mountains
By looking for tiny bumps in sea level caused by the gravity of subsurface mountains, researchers have roughly doubled the number of known seamounts.

‘The Deepest Map’ explores the thrills — and dangers — of charting the ocean
A new book follows the race to map the seafloor, documenting how it’s done, why and what a clear view of the deep sea could mean for Earth’s future.

Ancient giant eruptions may have seeded nitrogen needed for life
A new study bolsters the idea that on the young Earth volcanic lightning may have provided some materials that made it possible for life to emerge.

A ‘fire wolf’ fish could expand what we know about one unusual deep-sea ecosystem
Unlike other known methane seeps, Jacó Scar is slightly warmer than the surrounding water and is a home for both cold-loving and heat-loving organisms.

Sharks face rising odds of extinction even as other big fish populations recover
Over the last 70 years, large ocean fishes like tuna and marlin have been recovering from overfishing. But sharks continue to decline toward extinction.

By flying over atmospheric rivers, scientists aim to improve forecasts
Drenching atmospheric rivers are slamming the U.S. West Coast, bringing needed water but dangerous flooding. Here’s how scientists study these storms.

Mangrove forests expand and contract with a lunar cycle
The carbon-sequestering trees grow in a roughly 18-year cycle according to tides influenced by the moon’s orbit, a study in Australia finds.

Rapid melting is eroding vulnerable cracks in Thwaites Glacier’s underbelly
Thwaites is melting slower than thought, but the worst of it is concentrated in underbelly cracks, threatening the Antarctica glacier’s stability.

A massive cavern beneath a West Antarctic glacier is teeming with life
A subglacial river has carved out the cavern beneath the Kamb Ice Stream, a West Antarctic glacier, and may be supplying nutrients necessary for life.
