Taking Stewardship Underwater By Tracking Dredging Activity

Stewardship services apply beyond our shorelines into harbors, waterways and oceans. Beneath the surface of harbors, rivers and channels are contaminated sediments and  unexploded ordnance (UXO).   A common and disruptive offshore activity is dredging, which can unknowingly disturb these materials – often to unfortunate ends.
