... main sources of plume generation, the first being at the active mining site where the "collector" directly removes the top layer of the sea floor. The other is the "midwater plume" consisting of unwanted sediment that was collected during extraction that is pumped back into the aphotic zone. The vast...

... at the mudline, this kind of soils has very low undrained shear strength up to 20 kPa. In order to properly design the nodule harvester, which will be in contact with the sea floor, physical properties of the seabed and shallow subsurface (i.e. the upper 100–200m)are needed to compute bearing capacity...

... or passive margins are born, hydrate stability zones form and are destroyed. As new sediments are added to the sea floor, hydrates are buried and dissociate when burial becomes deep enough that they lie below the local limit of hydrate stability. They then reform when their gases migrate upward and reenter...
