Deep sea mining has ‘devastating’ impact on biodiversity
A landmark report into how deep sea mining could affect biodiversity on the sea floor has found that almost 40% of creatures in the immediate seabed area were lost in the tracks of mining machines.

A “lost” Argo float drifted under Antarctica’s ice shelves and resurfaced with a warning: warm water is creeping under major glaciers like Denman and Totten.
What’s at risk? Up to 5 m of global sea-level rise.

What our missing ocean float revealed about Antartica’s melting glaciers
Our ocean float spent years adrift in the Antarctic ocean and beneath massive ice shelves. What it found will help us estimate global sea-level rise.
