Seabed Mining - The Ocean Foundation

Seabed Mining (liming) is an experimental industrial field which involves extracting submerged minerals and deposits from the sea floor. There are interests both for and against seabed mining, however, the science around the environmental impact of liming is incomplete and unproven.

Deep Sea Mining

Deep Sea mining, like asteroid mining, is a relatively unconventional method of extracting Rare Earth elements (REEs). Unlike asteroid mining, however, deep sea mining has already been undertaken through projects such as deep sea diamond mining. Actual mining for REEs has not been attempted because of environmental issues and cost.
