The investigation

A living ocean.
An industrial frontier.

From the seabed to Pacific communities, Blue Peril examines a footprint that could extend beyond the mine.

01 / The seafloor

More than
mineral deposits.

Polymetallic nodules are part of the environment in which deep-sea organisms live.

The campaign highlights the physical destruction of habitat as nodules are collected. Removing the nodules also removes hard surfaces used by seabed life.

Blue Peril builds on a 2020 review of scientific literature on Pacific nodule mining. That review considers ecological risks alongside major gaps in what is known.

02 / The water column

Disturbance
does not stay still.

Mining can create more than one sediment plume.

Seabed collection disturbs sediment close to the bottom. Processing nodules on a support vessel can produce another source: a discharge of water and fine material back into the ocean.

Blue Peril models these pathways separately. The scenarios explore where particles might travel under specified current and settling assumptions.

03 / Pacific peoples

The ocean is
part of home.

For Pacific communities, the ocean connects food, livelihoods, identity and responsibility.

The Pacific Blue Line statement centers these relationships and calls for a global ban on deep-sea mining. It also welcomes moratoria adopted by some Pacific governments while asking for broader protection.

The Blue Peril toolkit links to this Pacific-led movement. Read its statement in the voices of the organizations and people who issued it.
