  • Impacted area is very small (diameter in the 100's m range.)
  • Production from SMS's will be performed through 'surgical interventions'.
  • Non-uniqueecosystems around inactive vents
  • Intermediate areas (50-100km2)
  • Steep slopes most likely favourable for development of crust on NCS.
  • Large areas (>250k km2)
  • "Easy" exploration.
  • The nodules can be harvested.
  • Probably relative low environmental impact.

Closed loop production system reduce/remove sediment plume during extraction for all deposits.
