Mallows Bay-Potomac River National Marine Sanctuary conducts research and monitoring activities in an effort to better understand, manage, and interpret maritime heritage resources and the surrounding ecosystem. A variety of activities, such as site mapping, water quality monitoring, submerged aquatic vegetation surveys, and acoustic telemetry help characterize the shipwrecks, key habitats, and species in the sanctuary, while community science projects connect volunteers to meaningful research efforts. Information gathered by the sanctuary, partners, and volunteers helps provide important insights to sanctuary co-managers.

Information about the science needs in Mallows Bay-Potomac River National Marine Sanctuary is available on the NOAA Office of National Marine Sanctuaries website.
