Abstract

The Laje de Santos Marine State Park (LSMSP) and Xixová-Japuí State Park (XJSP) are two protected areas (PA), close to the Santos Bay in the south Brazilian coast. The region encompasses both important biodiversity and anthropogenic activities. This study aims to serve as a first reference survey of the underwater soundscape of these PAs. Additionally it evaluates the presence of the anthropogenic and biological sound in these areas. One month of continuous recorded underwater sound, at selected locations in XJSP and LSMSP, is used in this study. The data were characterized by its spectral content and by the temporal evolution of Sound Pressure Levels (SPL). Both locations showed sound events with daily periodicities, mainly related with boats and fish chorus.

摘要

拉热德桑托斯海洋州立公园（LSMSP）和西绍瓦-雅普伊州立公园（XJSP）是巴西南部海岸靠近桑托斯湾的两个保护区。该地区既包含重要的生物多样性，也有人为活动。本研究旨在作为对这些保护区水下声景的首次参考调查。此外，它还评估了这些区域中人为声音和生物声音的存在情况。本研究使用了在XJSP和LSMSP选定地点连续记录的一个月水下声音。数据通过其频谱内容和声压级（SPL）的时间演变来表征。两个地点都显示出具有每日周期性的声音事件，主要与船只和鱼群合唱有关。
