Users can track ships as they search international waters for the “polymetallic nodules” on the ocean floor.

An environmental nonprofit and university researchers are applying marine vessel tracking technology to provide internet users a bird’s-eye view of global seabed mining activities.

The open-access online portal, called Deep-Sea Mining Watch, taps satellite signal technology to monitor industry ships as they search international waters for high-value metals on the ocean floor, including areas that have not been surveyed or studied by ocean scientists.

Those metals — including nickel, cobalt, copper and manganese — are bound up in potato-sized “polymetallic nodules” nestled within seafloor sediment thousands of feet below the ocean’s surface.

The web portal, co-developed by the nonprofit Global Fishing Watch and researchers at the University of California, Santa Barbara, will rely on a technology widely used by mariners called automatic identification systems. Such systems rely on satellite signals transmitted from moving ocean vessels to help pilots identify other ships and avoid collisions.
