Hydroacoustic Studies of Eulachon Fish Distribution Related to Roberts Bank Terminal 2 Project
ASL Environmental Sciences (ASL) was chosen by Hemmera Envirochem Inc. and the Vancouver Fraser Port Authority (port authority) to perform a hydroacoustic study of eulachon fish (Thaleichthys pacificus) distribution in the vicinity of Deltaport Terminals off the mouth of the Fraser River, BC. To support the development of the Dredging and Sediment Discharge Plan that will form part of the Construction Environmental Management Plan of the Roberts Bank Terminal 2 Project (project), the port authority has committed to developing eulachon-specific mitigation that will be used during dredging activitie
Seiche Unveils Acoustic Monitoring Technology
many cases, a direct measurement of hydrophone depth enhances 3D position fixing, as acoustic determination of depth depends on reflections from a variable or ‘unreliable’ surface. Mark Burnett, CEO at Seiche Water Technology Group, commented: “With ports such as the Vancouver Fraser Port Authority leading the way in underwater noise mitigation management plans, we see an increasing appetite for technology that can monitor multiple aspects of underwater noise enabling mitigation measures to be put in to place that reduce impact on marine mammals. Added to applications that
