The Great Barrier Reef is suffering its most widespread bleaching ever recorded
Major bleaching events are recurring with increasing frequency on the Great Barrier Reef, hindering its recovery.

Parasitic worm populations are skyrocketing in some fish species used in sushi
Fishes worldwide harbor 283 times the number of Anisakis worms as fishes in the 1970s. Whether that’s a sign of environmental decline or recovery is unclear.

Legos may take hundreds of years to break down in the ocean
Sturdy types of plastic may persist in seawater for much long than scientists previously thought.

Economic costs of rising seas will be steeper than we thought, unless we prepare
A study estimates 4 percent in annual global GDP losses by 2100 due to sea level rise, unless people curb emissions and prepare for flood risks.

The Deepwater Horizon oil spill spread much farther than once thought
Computer simulations reveal the full extent of the 2010 Deepwater Horizon oil spill in the Gulf of Mexico.

Noise pollution from ships may scare Arctic cod from feeding grounds
Melting Arctic sea ice is opening up northern waters to increased shipping, and the vessel noise is taking a toll on Arctic cod.

Climate change may be speeding up ocean circulation
Circulation in the top 2,000 meters of the world’s oceans has increased as a result of faster winds around the globe, a study suggests.

Ocean acidification could degrade sharks’ tough skin
Nine weeks of exposure to acidic seawater corroded the toothlike denticles that make up a puffadder shyshark’s skin, a small experiment found.

Flooding Earth’s atmosphere with oxygen may not have needed a triggering event
Building an oxygen-rich world doesn’t require volcanism, supercontinent breakups or the rise of land plants — just nutrient cycling, a study finds.

How the Arctic’s poor health affects everyday life
A new NOAA report features testimony from indigenous communities in Alaska who are weathering the impacts of Arctic warming.

Stealthy robots with microphones could improve maps of ocean noise
Recordings from underwater microphones on stealthy robotic gliders could create a better “soundscape” of noises throughout the ocean, researchers say.

Plastics outnumber baby fish 7-to-1 in some coastal nurseries
Ocean slicks serve as calm, food-rich nurseries for larval fish. A new study shows that slicks also accumulate plastics, which get eaten by baby fish.
