2 Meanwhile, specialized offshore dredging ships mine sand from seafloor deposits so that it can be pumped back onto the beach a process called nourishment, although it is hardly that. Such beaches tend to be structurally unstable, since they are part of a larger submerged mass, and mining at the base of that mass destabilizes the whole. 17
