The ocean twilight zone could store vast amounts of carbon captured from the atmosphere – but first we need an internet of deep ocean sensors to track the effects

The ocean twilight zone could store vast amounts of carbon captured from the atmosphere, but first we need a 4D monitoring system to ensure ramping up carbon storage does no harm.
When fish like this netted cod are exposed to mercury, it accumulates in certain organs, including the lenses of their eyes. Yvette Heimbrand

The lenses of fishes’ eyes record their lifetime exposure to toxic mercury, new research finds

A new study shows that a time stamp can be put on mercury that accumulates in fish eyes, offering a window into their lifetime exposure.
Researchers discovered five new species of black corals, including this Hexapathes bikofskii growing out of a nautilus shell more than 2,500 feet (760 meters) below the surface. Jeremy Horowitz

Scientists discover five new species of black corals living thousands of feet below the ocean surface near the Great Barrier Reef

Black corals provide critical habitat for many creatures that live in the dark, often barren, deep sea, and researchers are learning more about these rare corals with every dive.

How you can help protect sharks – and what doesn’t work

Sharks are much more severely threatened by humans than vice versa. A marine biologist explains how people can help protect sharks and why some strategies are more effective than others.

Do chemicals in sunscreens threaten aquatic life? A new report says a thorough assessment is ‘urgently needed,’ while also calling sunscreens essential protection against skin cancer

Rising concern about possible environmental damage from the active ingredients in sunscreens could have ripple effects on public health if it causes people to use less of them.

The ocean is not a quiet place

The ocean is often considered a silent universe. But many recent studies highlight the importance of the soundscape for many marine species, both large and small.
There are even more types of viruses in the ocean than researchers once thought. newannyart/iStock via Getty Images Plus

Researchers identified over 5,500 new viruses in the ocean, including a missing link in viral evolution

Viruses do more than just cause disease – they also influence ecosystems and the processes that shape the planet. Tracing their evolution could help researchers better understand how viruses work.
