A monitoring survey was conducted in 2012 at the Eastern Passage Disposal Site (EPDS) as part of the Disposal Area Monitoring System (DAMOS) Program. The 2012 monitoring effort involved a high-resolution acoustic survey to characterize seafloor topography and dredged material distribution, as well as sediment-profile imaging (SPI) and plan-view imaging (PV) surveys to provide additional physical characterization and to assess benthic recolonization. The results of the 2012 surveys were used to document changes at EPDS since placement of approximately 52,000 m^3 of dredged material at the site.
