TMC describes its commercial nodule collection system's trip. The nodule's journey from seafloor to surface vessel takes about 25 minutes.

TMC executive Rutger Bosland details how nodules reach the surface. The design draws on more than 50 years of offshore industry innovation.

TMC used ROVs to image seafloor life near its test mining site. A year after mining, ROV images showed nodules shed sediment, becoming habitat again.

Allseas designed a diffuser system to slow discharged sediment flow. Over 95% of the sediment stays within the gravity current near the seabed.

TMC dropped box core samplers at hundreds of sites on the seafloor. Each core lifted a square meter of seabed to count nodules and sediment life.
