Underwater wreck survey

Disarming the ecological timebombs of WW2, honouring the fallen by protecting the future they fought for.

Project Guardian is an intelligence-led mission to make safe the toxic legacy of more than 8,500 WWII shipwrecks before they fail and pollute the waters around them.

More than environmental risk

Many of these wrecks are also war graves. The vessels that lie on the seabed across the Pacific, the Atlantic, the Mediterranean, and the Arctic carry not only fuel and munitions but the remains of those who served and died on them. Project Guardian works only with the consent of the relevant coastal state and, where appropriate, the flag state. The wreck structures and the remains they hold are preserved in situ; what is removed is the threat they pose to the surrounding environment.

A pre-emptive response can be respectful in ways that an emergency response cannot afford to be.

A present-day crisis

This is not a distant historical issue. A reactive “wait-and-see” approach is no longer tenable. Only a systematic, preventative strategy can address this legacy before irreversible harm occurs.

  • Chronic leaks: Persistent seepage at heritage wrecks indicates unmanaged ongoing release potential.
  • Sunken fleets: Clustered WWII vessel groups place reef ecosystems under cumulative stress.

An accelerating threat

The passage of time is not the only factor. Increasing environmental instability is accelerating the decay of these wrecks. More frequent and intense storms, seismic activity in vulnerable zones, and the chemical effects of ocean warming and acidification are placing immense stress on these corroding hulls. Each earthquake or major storm could trigger a catastrophic failure and a major pollution event.

Operational capability

How the intelligence platform is delivered into the water.

Project Guardian's intelligence platform is delivered into the water by Deeptrek, a marine specialist operation with a forty-year lineage tracing back to its founding in 1986. Deeptrek's current capability combines deep-water environmental intervention, wreck and salvage leadership, and Unmanned Surface Vessel (USV) command-and-control technology.

Subsea operations are delivered through Deeptrek's established technology partnerships with industry-leading providers of subsea laser and photogrammetric imaging systems and professional-grade remotely operated vehicles. Where in-water remediation is required following survey, Deeptrek works with regional marine salvage and project specialists who can be brought in under appropriate consent and contractual arrangements.
