Proactive Limits on Seabed Mining Would Safeguard West Coast Fisheries, Wildlife, and Communities
Last Updated April 14, 2021

Mining the nearshore seafloor along the U.S. West Coast could cause significant damage to commercial and recreational fisheries, marine wildlife, and the communities and tribal nations that depend on them. Industrial-scale prospecting for gold, platinum, titanium, phosphorus, and other minerals along the ocean floor is increasing worldwide. By preventing this harmful activity before it starts, the West Coast can be a model for other regions that are hoping to avoid the possible consequences of seabed mining.

Seabed Mining Could Threaten West Coast Fisheries

Thirty years ago, scientists tested the potential effects of seabed mining by dragging a plow over a swath of ocean floor in the eastern Pacific Ocean, resulting in a sediment plume that buried the study area. The plow tracks from that 1989 experiment remain visible to this day, a testament to the lasting damage seabed mining could inflict.

Data-driven policymaking is not just a tool for finding new solutions for emerging challenges, it makes government more effective and better able to serve the public interest. In the coming months, President Joe Biden and the 117th Congress will tackle a number of environmental, health, public safety, and fiscal and economic issues—nearly all of them complicated by the COVID-19 pandemic. To help solve specific, systemic problems in a nonpartisan fashion, Pew has compiled a series of briefings and recommendations based on our research, technical assistance, and advocacy work across America.

Data-driven policymaking is not just a tool for finding new solutions for difficult challenges. When states serve their traditional role as laboratories of innovation, they increase the American people’s confidence that the government they choose—no matter the size—can be effective, responsive, and in the public interest.

The cold, dark waters of the deep sea once were thought to be largely void of life, but scientists now know that the opposite is true. Underwater mountain chains teem with fish, corals, and other fauna and flora. Hydrothermal vents gush mineral-rich waters that support communities of deep-sea organisms. Unusual animals, many of which have yet to be identified, roam these surreal landscapes.
