2.2 Conventional Deep-Sea Mining Models Conventional deep sea mining systems rely on bulk collection methods in which machines travel along the seabed and use suction or scraping mechanisms to collect polymetallic nodules along with surrounding sediment. Because nodules sit on or partially within soft seabed sediments, these systems inherently disturb large areas of the seafloor during collection. This disturbance resuspends sediment, creating plumes and affecting life living on and near the seabed. These approaches, typically combined with riser-pump systems to transport material to the surface, have raised concerns about the scale of seafloor disturbance, sediment redeposition, and the introduction of light, noise, and discharge effects across large areas of the deep ocean. As a result, public confidence in early deep sea mining concepts has remained limited, and regulatory scrutiny has increased. The central issue is not the existence of deep sea mineral resources, but whether they are accessible in a way that limits environmental disturbance, supports regulatory confidence, and is scalable responsibly within the timeframes required to meet future mineral demand. 3. MINING 2.0: A NEW FRAMEWORK Mining 2.0 focuses on using precision-based, carefully designed systems to limit environmental disturbance while still supplying usable mineral resources. Four core principles form the foundation of the framework: 3.1 Selectivity Over Scale Rather than removing continuous swaths of seabed material, Mining 2.0 focuses on identifying and collecting individual polymetallic nodules, reducing the amount of sediment and visible life disturbed during collection, and limiting the physical footprint of operations. 3.2 System Integration Collection, transport, monitoring, and environmental considerations are addressed together rather than as separate challenges. Decisions made at the point of collection directly influence operational control and environmental outcomes. 3.3 Environmental Performance By Design The system limits environmental harm through its design, rather than trying to fix problems after the fact. It reduces disturbance by using precise collection methods that avoid unnecessary disruption in the first place. 3.4 Governance Alignment The approach works within regulatory systems that prioritize transparency, accountability, and clear oversight. Together, these principles shift mining away from force-based, high-throughput approaches toward more deliberate, controlled interactions with the deep sea environment.
