A setup for measuring spectral source levels (SSLs) of ships transiting along a seaway, the traffic density and shipping noise, is presented. The results feed shipping-noise modeling that reproduces the actual in situ observations to map shipping-noise variability over space and time for investigating its effects on aquatic organisms. The ship's SSL databank allows sorting the different contributors to total shipping noise for assisting in exploring mitigation approaches (e.g., fleet composition, rerouting). Such an acoustic observatory was deployed since November 2012 for a complete annual cycle of measurements in the deep downstream part of the St. Lawrence Seaway.
本文介绍了一种用于测量沿航道航行船舶的频谱源级(SSL)、交通密度和航运噪声的装置。这些结果为航运噪声建模提供了数据,该模型可再现实际现场观测结果,以绘制航运噪声在空间和时间上的变化情况,从而研究其对水生生物的影响。船舶的SSL数据库能够对造成总航运噪声的不同因素进行分类,有助于探索缓解措施(例如,船队构成、改道)。自2012年11月起,这样一个声学观测站已在圣劳伦斯航道下游深处部署,进行了一整年的完整测量。
