Deep sea mining could supply valuable rare minerals to green technology, but one project in the south-west Pacific is invoking the wrath of local spirits.

When you study volcanoes at mid-ocean ridges, doing fieldwork means becoming an aquanaut – diving thousands of feet to the ocean floor in the submersible Alvin, trading tight quarters for amazing views.
Tiny chemical clues in the ocean reveal how its role as a carbon store is changing.
Nature’s bank vault.
The sediments that accumulate beneath seagrass meadows can act as secure vaults for shipwrecks and other precious artefacts, by stopping water and oxygen from damaging the delicate timbers.
In contrast to common perceptions, Antarctic seafloor communities are highly diverse. This image shows a deep East Antarctic reef with plenty of corals, sponges and brittlestars. Can you spot the octopus?
Australian Antarctic Division
Life on the Antarctic seafloor is surprisingly diverse – and half of the species live nowhere else on Earth. Now scientists can accurately map this unique biodiversity.
Seismic shockwaves after a meteorite’s collision could affect systems all over the planet.
Research suggests a new threat to life on Earth from the meteorite's crash: Via seismic waves, the impact triggered massive undersea eruptions, as big as any ever seen in our planet's history.
The Byron Scar, left behind by an undersea landslide. Colours indicate depths.
The ocean floor off Australia's east coast bears the scars of numerous subsea landslides, which have potentially triggered tsunamis over the past several millennia.
