This is the first study to look at the impact of mining the seafloor

A study by the Natural History Museum , London , looked at a site that was mined as part of an experiment back in 1979 .

The study found clear evidence of long-term changes to the sediments, with an 8-meter section of seafloor cleared of nodules.

The sediment surface was once again home to a number of small and mobile animals, including an amoeba-like xenophyophore.

The story was very different for larger animals, but some were still very rare and showed little sign of recovery, and we don’t yet know what that could mean for the wider ecosystem.

A system of protected areas in the region covers almost 2 million square km .

That is about 30 percent of the area under exploration, but what we don’t know is how useful these regions are as we have not studied their biodiversity to compare it to the contracted areas.

If we can get a good handle on the species that live in these protected regions then we will be able to assess the potential for biodiversity loss caused by mining.
