Scientists at work: New recordings of ultrasonic seal calls hint at sonar-like abilities

Microphones on the seafloor recorded life under the Antarctic ice for two years – inadvertently catching seal trills and chirps that are above the range of human hearing. Could they be for navigation?

When hurricanes temporarily halt fishing, marine food webs recover quickly

Hurricane Harvey destroyed the fishing infrastructure of Aransas Bay and reduced fishing by 80% over the following year. This removed humans from the trophic cascade and whole food webs changed.

A rush is on to mine the deep seabed, with effects on ocean life that aren't well understood

Companies are eager to mine the deep ocean for valuable mineral deposits. But scientists are concerned about impacts on sea life, including creatures that haven't even been discovered yet.

The Moon and stars are a compass for nocturnal animals – but light pollution is leading them astray

Towns and cities create an orange glow on the horizon at night. It's so widespread that it even disturbs sea creatures.

Abandoned fibreglass boats are releasing toxins and microplastics across the world

Too many small yachts and speedboats are simply being abandoned to shed toxins and microplastics into the sea.

Microplastics: tiny crustaceans can fragment them into even smaller nanoplastics

The discovery that such a common animal can rapidly produce vast numbers of nanoplastics is particularly worrying.

With the help of trained dolphins, our team of researchers is building a specialized drone to help us study dolphins in the wild

Wild dolphins are fast, smart and hard to study, but it is important to understand how human actions affect their health. So we are building a drone to sample hormones from the blowholes of dolphins.

Tiny plankton drive processes in the ocean that capture twice as much carbon as scientists thought

Microscopic ocean phytoplankton feed a "biological pump" that carries carbon from the surface to deep waters. Scientists have found that this process stores much more carbon than previously thought.
