Underwater Noise Baseline Data Assessment for Doha Causeway

Mawael Environmental Consultancy, as a subcontractor to Wataniya Environmental Services (WES), conducted the baseline assessment and interpretation of underwater acoustic monitoring data collected for the Doha Causeway Project. The assignment involved processing approximately 48-hour underwater recordings captured using RTSYS acoustic recorder systems, including quality assurance, hydrophone sensitivity verification, temporal and spectral analysis, signal screening, and comprehensive post-processing of raw waveform data. Acoustic datasets were organized into dedicated databases and analyzed using ESP3 open-source software and customized MATLAB processing routines to ensure consistent interpretation of underwater sound conditions. The resulting baseline assessment established a robust acoustic reference for future environmental impact assessments and underwater noise modelling associated with the Doha Causeway development.
