Deep sea mining threatens unique marine life, experts warn

Jun 26, 2017With the deep seabed environment still largely unexplored, mining may lead to the loss of undiscovered species, making biodiversity offsets impossible. Out-of-kind biodiversity offsets, which involve restoring or preserving very different marine habitats like tropical coral reefs, cannot compensate for the loss of unknown deep-sea species.

Seafloor Mining

Seafloor Mining. Hot, buoyant, mineral-laden fluids rise from deep within ocean crust and mix with cold seawater. That triggers the precipitation of minerals that form deposits near and on the seafloor. Precipitating minerals also form seafloor chimneys, and mineral particles in the fluids venting at the seafloor make the fluids look like smoke.
