Anthropogenic impulsive sound dataset in support of the Marine Strategy Framework Directive (MSFD) Descriptor 11 (D11C01, 2018 Reporting)

This dataset is part of the 2018 Belgian submission for the Marine Strategy Framework Directive (MSFD) linked to descriptor 11, criterion 1. This dataset describes the impulsive noise generated during percussion pile emplacement for offshore wind farm construction and unexploded ordnance (UxO) explosions. Impulsive underwater sound (pressure) was measured during pile driving operations in Belgian waters, for different types of foundations (monopiles of different diameters, foundations of ducts with a smaller diameter) and hydraulic hammers with different energy powers. The results of measurements at Bligh Bank and Thornton Bank, with a resulting extrapolation of zero to peak noise level (Lz-p) at 750m and Sound Exposure Level (SEL) (no mitigation measures deployed), are presented (Norro et al., 2013).本数据集隶属于2018年比利时针对《海洋战略框架指令》（Marine Strategy Framework Directive, MSFD）提交的申报材料，对应其中第11项描述项及第1项标准。本数据集涵盖海上风电场建设期间冲击打桩作业产生的脉冲噪声，以及未爆炸弹药（Unexploded Ordnance, UxO）爆炸所引发的噪声。研究团队针对比利时海域内的打桩作业开展了脉冲水下声（声压）测量，测试对象涵盖多种桩基基础（不同直径的单桩基础、小直径导管基础）以及不同功率等级的液压打桩锤。本研究呈现了在布莱浅滩（Bligh Bank）与桑顿浅滩（Thornton Bank）获取的测量结果，其中包含未部署任何降噪措施时，750米处的零到峰值噪声级（Lz-p）与声暴露级（Sound Exposure Level, SEL）的外推数值（Norro等，2013）。
