Archipelago was contracted by the Fraser River Pile and Dredge on behalf of Public Services and Procurement Canada to provide environmental monitoring services during the South Jetty Reconstruction project at the Esquimalt Graving Dock in the Greater Victoria area. Archipelago monitored the marine environment during in-water construction to identify possible risks or impacts to the environment, and to ensure the work was being carried out in accordance with regulatory and contractual obligations. To meet these criteria, Archipelago staff monitored and documented: water quality; acoustic levels; marine fish and wildlife presence; environmental incidents and mitigation; best management practices; and site cleanliness. Daily and weekly reports were prepared throughout the duration of the project for in-water construction activities. Archipelago employed and reported on data collected using multiple survey methods during environmental monitoring. In-situ water quality measurements were recorded and assessed using a CTD instrument. Water samples were collected and submitted for lab analysis using niskin bottles. Construction sound levels were measured and assessed using a hydrophone. Marine fish and wildlife within the work area were documented from the research vessel. Upon the project’s completion in 2020, Archipelago prepared a final report summarizing monitoring data collected, construction activities, environmental management mitigation measures, additive measures, and recommendations.
