March 2013 Bathymetric Survey of the Black Point Dredged Material Disposal Site, Saint John Harbour, NB

Each year in Canada between two and four million tonnes of materials are disposed of at marine disposal sites. The majority of these materials is dredged sediment from estuarine or marine locations. Under the authority provided by the Canadian Environmental Protection Act 1999, Environment Canada regulates the use of marine disposal sites and monitors environmental conditions at representative sites. Monitoring assesses on-site and off-site environmental effects such as changes to seabed morphology, environmental quality, habitat alteration and cumulative effects. In March 2013, as part of its Disposal Site Monitoring Program, Environment Canada contracted Public Works and Government Services Canada to conduct a bathymetric survey of the Black Point Dredged Material Disposal Site. The disposal site is located in the outer waters of Saint John Harbour, NB and over a period of several decades has received dredged materials from various locations in the harbour. The survey covered a trapezoidal area of approximately 2 square kilometers ranging in depth from 5 to 27 meters. Survey equipment used included a 200 kHz multi-beam system, inertial motion sensor, and sound velocity profiler. The multi-beam data was post-processed using hydrographic processing software. Data are available in a number of mapping formats.



Data were collected for environmental monitoring purposes and are not to be used for navigation.
