Abstract

As part of the European Union Marine Strategy Framework Directive (MSFD), member states are required to address noise pollution in the marine environment under Descriptor 11. This study aimed to provide a practical desk-based application of Descriptor 11 assessment, focusing on the main contributors of ocean noise pollution in Irish waters, seismic surveying and shipping. To highlight specific geographical areas subject to elevated levels of noise pollution, the proportion of days over a calendar year that seismic air guns were operational was calculated and the vessel density per 50-km(2) grids was determined across Ireland's exclusive economic zone (EEZ). Additionally, cetacean sighting data were used to determine the degree of spatial overlap between areas of elevated noise pollution and areas of cetacean abundance.

摘要

作为欧盟海洋战略框架指令（MSFD）的一部分，成员国需要根据描述符11解决海洋环境中的噪声污染问题。本研究旨在提供一种基于桌面的实用描述符11评估应用，重点关注爱尔兰海域海洋噪声污染的主要来源，即地震勘探和航运。为了突出受高水平噪声污染影响的特定地理区域，计算了一历年中地震气枪作业的天数比例，并确定了爱尔兰专属经济区（EEZ）内每50平方公里网格的船只密度。此外，利用鲸类动物目击数据来确定高噪声污染区域与鲸类动物丰富区域之间的空间重叠程度。
