Fake fog, ‘re-skinning’ and ‘sea-weeding’ could help coral reefs survive
Coral reefs are in global peril, but scientists around the world are working hard to find ways to help them survive the Anthropocene.

10 billion snow crabs have disappeared off the Alaskan coast. Here’s why
In the eastern Bering Sea, the snow crab population plummeted after a marine heat wave in 2018. The crabs may have starved, a new study finds.

‘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.

Extreme ocean heat off Florida has ebbed. But for marine life, the danger remains
After the recent heat wave, corals have received too much heat too early in the summer, and other sea life could see lingering effects too.
- Climate
Antarctic sea ice has been hitting record lows for most of this year
Since hitting a record low minimum back in February, the amount of Antarctic sea ice has stayed well below normal all year.

Irrigation may be shifting Earth’s rotational axis
Computer simulations suggest that from 1993 to 2010 irrigation alone could have nudged the North Pole by about 78 centimeters.
- Life
5,000 deep-sea animals new to science turned up in ocean records
Scientists compiled a list of animals unknown to science that live in a deep-sea Pacific Ocean ecosystem targeted for mining exploration.

In one lake deep under Antarctica’s ice, microbes feast on ancient carbon
Microorganisms living in a lake beneath the ice sheet in West Antarctica feed on ocean carbon that was deposited 6,000 years ago.

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.

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.

‘Jet packs’ and ultrasounds could reveal secrets of pregnant whale sharks
Only one pregnant whale shark has ever been studied. New underwater techniques using ultrasound and blood tests could change that.

50 years ago, researchers discovered a leak in Earth’s oceans
An analysis of oceanic rocks hinted that ocean water drains into Earth’s mantle. How much makes it back into the ocean remains unclear.
