HOW SLR CAN HELP
SLR combines extensive experience in acoustics with in-house ecological expertise. Coupled with key academic peer review partnerships, we can deliver a full suite of underwater acoustics services, including baseline studies, numerical modeling, detailed impact assessment, and mitigation design and implementation.
Underwater noise emissions and their
potential impact on the environment and marine fauna are increasingly becoming an issue for environmental regulators and other stakeholders.
UNDERWATER ACOUSTICS
TECHNICAL SERVICE
Underwater Noise Measurement and Baseline StudiesSLR employs custom designed underwater noise data acquisition systems, incorporating state of the art hydrophones and signal processing software, in order to measure and analyze underwater noise sources. SLR has developed an extensive measurement database of underwater noise sources for use as reference source noise levels in noise modeling applications. We have measured and developed a robust set of site laws for higher risk, high noise generating activities, such as marine piling and underwater blasting.
Underwater Noise ModelingAn important initial step in the noise impact assessment process is to determine the level of noise emissions that may result from a particular activity or development. Having an understanding of these levels allows for decisions in relation to the appropriateness of the activity and any need for management measures. Underwater noise levels can be determined directly via measurement of similar activities at representative sites, or predicted from reference data and modeling.
Environmental AssessmentSLR has undertaken extensive research into the potential effects of underwater noise emissions on marine fauna in consultation with our in house ecology team and associated expert academic reviewers. We are therefore able to determine the potential zones of impact for specific species, whether it be for large marine mammals, turtles or fish, and relevant to the proposed construction or operational activities. The combination of detailed empirical or numerical modeling techniques and specific knowledge of species specific impacts allows SLR to develop and implement common sense, practical strategies to manage the potential impacts of underwater noise on marine fauna.
Environmental Management Design and ImplementationMitigation of underwater acoustic risk to marine fauna and marine infrastructure includes the design and implementation of a practical and cost effective management plan. These may include measures such as Passive Acoustic Monitoring, Visual Observation (e.g. Marine Mammal Observers) and long-term statistical monitoring of marine fauna. SLR has also developed and presented training materials for clients in relation to Marine Mammal Observation on a project specific basis.
