The radiated noise that emanates from the movement of ships globally is known to double every decade since 1950, posing a harmful impact on the marine life. The emerging geo-strategic relevance of the in the Indian Ocean Region (IOR) has ensured that this increase in the low-frequency shipping noise may be worse than the global average. The surge in the deaths of marine mammals along the coastline could be attributed to the increase in traffic along the major shipping routes, a study said. \u201cThe low-frequency ambient noise due to shipping in the IOR is attributable to the surge in big whale stranding in the west coast, according to a study by Maritime Research Centre (MRC), Pune. Considering the strategic significance of the IOR on the world map, the geo-economic and geopolitical issues in the region determine the global matters, further aggravating the problem. \u201cThe direct linkage of shipping traffic with the global economic index makes it extremely difficult to motivate the political leadership to contain or regulate the shipping traffic,\u201d the study, Acoustic Habitat Degradation Due to Shipping in the Indian Ocean Region (IOR), stated. \u201cThe low-frequency shipping noise propagates to long distance as it gets least attenuated in the undersea medium. This coupled with the geographically well-distributed shipping traffic makes it a very complex mix to drive any conservation initiative. Further, the direct link of the shipping traffic with the economic growth engines makes it politically unviable to bring regulatory provisions. The opening of the north route for shipping will probably bring disaster in terms of the big whale population management\u201d, Dr Arnab Das, the author of the study told FE Online. All the activities critical to the survival of marine life are being interfered with, studies said, by the increasing levels of noise from ocean-going ship engines, sonar devices, and seismic exploration. Climate change could make the noise problems for marine mammals even worse, several studies have shown. MRC also carried out spatiotemporal mapping of the sound exposure level (SEL) for whales in the low-frequency band of 20 hertz (Hz) to 3 kilohertz (kHz). \u201cThe Acoustic Habitat Degradation is a much serious concern particularly due to the lack of awareness among the policymakers and the practitioners. The conservation efforts somehow ignore the noise aspect of the marine habitat resulting in the sub-optimal response. Globally, there are significant initiatives to address this increasing radiated noise from shipping," said Dr Arnab Das.
