Assessing the impact of the pile-driven signal on the selected marine species from Indian waters

Rising anthropogenic activities in the ocean have caused underwater noise pollution, which affects marine habitats in many ways.The present study assessed the impact of impulsive signals generated by a piling station on a few selected marine fishes in the Arabian Sea.A modelling approach has been employed to simulate the propagation of pile-driven signals in the low-frequency band.The present study found that pile driving had a significant impact on the hearing thresholds of selected marine fishes.The impact area of pile driving, estimated through the acoustic transmission loss model, was found to vary with environmental conditions and frequency.The study emphasises the need to establish mitigation techniques to lessen the impact of noise pollution on the maritime ecosystem.
