Seismic surveys disrupt cetacean communication: 50% call reduction threatens migratory corridors and marine ecosystems

Indigenous maritime cultures (e.g., Māori, Inuit, Pacific Islanders) possess millennia-old knowledge systems linking whale behavior to ecosystem health, where silence signals disturbance. These traditions often frame noise pollution as a violation of sacred relationships between humans and marine life, offering ethical frameworks to challenge industrial exploitation. However, such perspectives are systematically excluded from policy discussions, which privilege Western scientific metrics over holistic ecological wisdom.

The shift from harpoon-based whaling to sonar and seismic surveys in the 20th century marked a turning point in marine acoustic pollution, with documented declines in whale populations correlating with industrial noise expansion. Historical records from the 1950s show fin whale populations in the North Atlantic halved within decades due to combined pressures of hunting and noise, foreshadowing today’s crises. Yet modern regulatory frameworks fail to acknowledge this cumulative legacy, treating each new survey as an isolated event rather than part of a century-long pattern of exploitation.

Cross-culturally, whales are revered as symbols of wisdom and ecological balance, from the Norse *Jörmungandr* to the Aboriginal Australian *Waa the Crow*. In Japan, *kujira* (whales) are central to Shinto beliefs, where their suffering is seen as a disruption of *kami* (divine harmony). These diverse cultural narratives converge on a shared understanding of whales as sentinels of ocean health, yet industrial interests dismiss such framings as 'unscientific,' erasing the moral dimensions of conservation.

Seismic surveys emit low-frequency pulses (10–300 Hz) that travel vast distances, masking whale communication frequencies (10–20 Hz) and inducing stress responses detectable in cortisol levels. Peer-reviewed studies confirm that chronic noise exposure reduces reproductive success in cetaceans by disrupting mating calls and foraging efficiency. However, industry-funded research often downplays these findings, citing 'adaptation' or 'temporary displacement' to justify continued surveys.

Artistic and spiritual traditions often depict whales as messengers between worlds, with their songs carrying ancestral knowledge (e.g., Aboriginal songlines, Hawaiian *moʻolelo*). Contemporary artists like Susan Point (Coast Salish) use whale imagery to critique industrialization, while composers like John Luther Adams create symphonies (e.g., *Become Ocean*) to evoke the drowning of marine ecosystems. These creative acts challenge the commodification of nature by industrial capitalism, framing silence as a form of ecological grief.

Future scenarios modeling the collapse of whale populations under continued seismic surveying predict cascading effects on marine food webs, including declines in fish stocks and phytoplankton productivity. Alternative models show that transitioning to renewable energy infrastructure (e.g., offshore wind) could reduce ocean noise by 60% while creating jobs in coastal communities. However, these pathways require dismantling fossil fuel subsidies and investing in non-invasive survey technologies like passive acoustics and AI-driven monitoring.

Coastal communities in the Global South, particularly in West Africa and Southeast Asia, bear disproportionate burdens from seismic surveys, facing food insecurity and cultural erosion as fish stocks decline. Women-led fisheries cooperatives in India and the Philippines have documented whale strandings linked to survey noise, yet their testimonies are excluded from policy forums dominated by industry lobbyists. Similarly, small-scale fishers in Galicia (Spain), where the study was conducted, report reduced catches during surveys, but their knowledge is dismissed as 'anecdotal.'
