POSSIBLE IMPACT
Destruction of Local Aquaculture & Shellfish Industries
Our economy relies heavily on pristine water quality for clam and oyster aquaculture. Industrial-scale hydraulic suction dredging vacuums up seabed sediment, creating massive underwater plumes. These sediment plumes block out sunlight and can drift into nearshore waters. As fine silt settles, it threatens to smother sensitive shellfish beds, clog biological feeding filters, and harm local seafood harvests.
Irreversible Harm to Barrier Island Conservation
The Eastern Shore's string of barrier islands serves as a critical, fragile buffer against intense Atlantic storms and sea-level rise. Seabed mining alters natural seafloor topography, which can shift offshore wave energy and change tidal currents. Even minor disruptions to these offshore dynamics risk accelerating coastal erosion, altering sand distribution patterns, and undermining ongoing barrier island conservation efforts.
Ecological Collapse & Acoustic Threats to Marine Life
Dredging physically obliterates the complex aquatic habitats that support the bottom of the marine food web. Additionally, the continuous low-frequency acoustic noise from heavy mining pumps disrupts critical navigation and communication corridors. This poses a severe acoustic threat to migrating marine mammals, including the critically endangered North Atlantic right whale.
Devastation of Offshore Sportfishing and Essential Fish Habitat
The targeted dredging will obliterate the very structures that define our regional Essential Fish Habitat (EFH). These features are crucial biological hotspots that aggregate forage fish, squid, and benthic organisms. Stripping these layers will cause a multi-year collapse of the local food web, driving prized coastal game fish—including striped bass, cobia, bluefish, and tuna—away from our traditional recreational fishing grounds.
