The waters of the Cres-Lošinj archipelago are subject to intense boat traffic related to the high number of leisure boats frequenting this area during the summer tourist season. Boat noise dominates the acoustic environment of the local bottlenose dolphin (Tursiops truncatus) population. This study investigates the spatial and temporal change in the underwater noise levels due to intense boating, and its effect on the distribution of the bottlenose dolphins. In the period 2007-2009 sea ambient noise (SAN) was sampled across ten acoustic stations. During data collection the presence of leisure boats was recorded if they were within 2 km of the sampling station. Bottlenose dolphin spatial distribution was monitored in the same period. Results showed a strong positive correlation between high SAN levels and boat presence, particularly in the tourist season. Dolphin distribution indicated significant seasonal displacements from noisy areas characterized by the intense leisure boating.
克雷斯-洛希尼群岛的水域受到大量休闲船只的影响,这些船只在夏季旅游旺季频繁经过该地区,导致船只噪音成为当地宽吻海豚(Tursiops truncatus)种群声学环境的主要噪声源。本研究调查了由于船只密集而导致的水下噪声水平的时空变化及其对宽吻海豚分布的影响。在 2007 年至 2009 年期间,在十个声纳站进行了海态噪声(SAN)采样。在数据收集期间,如果休闲船只在采样站 2 公里范围内,会记录船只的存在情况。同时在同一时期监测了宽吻海豚的空间分布。结果表明,高 SAN 水平与船只存在之间存在很强的正相关关系,尤其是在旅游旺季。海豚的分布表明,它们会从以休闲船只为主的嘈杂区域显著季节性转移。
