High-intensity, impulsive sounds are used to locate oil and gas reserves during seismic exploration of the seafloor. The impacts of this noise pollution on the health and mortality of marine invertebrates are not well known, including the silverlip pearl oyster (Pinctada maxima), which comprises one of the world's last remaining significant wildstock pearl oyster fisheries, in northwestern Australia. We exposed ≈11,000 P. maxima to a four-day experimental seismic survey, plus one vessel-control day. After exposure, survival rates were monitored throughout a full two-year production cycle, and the number and quality of pearls produced at harvest were assessed. Oysters from two groups, on one sampling day, exhibited reduced survival and pearl productivity compared to controls, but 14 other groups receiving similar or higher exposure levels did not. We therefore found no conclusive evidence of an impact of the seismic source survey on oyster mortality or pearl production.
高强度、脉冲式的声音被用于海底地震勘探中寻找石油和天然气储备。这种噪声污染对海洋无脊椎动物的健康和死亡率的影响尚不清楚，包括银唇珍珠贝（Pinctada maxima），它是世界上最后剩下的重要野生珍珠贝渔业之一，位于澳大利亚西北部。我们将约 11000 个 P. maxima 暴露在为期四天的实验性地震调查中，外加一天船只对照。暴露后，我们在整个完整的两年生产周期中监测存活率，并在收获时评估所产珍珠的数量和质量。与对照组相比，在一个采样日，有两组珍珠贝的存活率和珍珠产量下降，但其他 14 组接受了类似或更高的暴露水平，并没有下降。因此，我们没有确凿的证据表明震源调查对牡蛎死亡率或珍珠产量有影响。
