Abstract. The paper presents information about the seismic experiment AniMaLS which aims to provide a new insight into the crustal and upper mantle structure beneath the Polish Sudetes (NE margin of the Variscan orogen). The seismic array composed of 23 temporary broadband stations was operating continuously for ~2 years (October 2017 and October 2019). The dataset was complemented by records from 8 permanent stations located in the study area and in the vicinity. The stations were deployed with inter-station spacing of approximately 25–30 km. As a result, good quality recordings of local, regional and teleseismic events were obtained. We describe the aims and motivation of the project, the stations deployment procedure, as well as the characteristics of the temporary seismic array and of the permanent stations. Furthermore, this paper includes a description of important issues like: data transmission set-up, status monitoring systems, data quality control, near-surface geological structure beneath stations and related site effects etc. Special attention was paid to verification of correct orientation of the sensors. The obtained data set will be modelled using several seismic interpretation methods, including analysis of seismic anisotropy parameters, with the objective of extending knowledge about the lithospheric and sub-lithospheric structure and the tectonic evolution of the study area.

波兰Sudetes（NE Variscides）的被动地震实验“ AniMaLS”

摘要。本文介绍了有关地震实验AniMaLS的信息，该实验旨在为波兰Sudetes（Variscan造山带的NE边缘）下方的地壳和上地幔结构提供新的见解。由23个临时宽带站组成的地震阵列连续运行了大约2年（2017年10月和2019年10月）。该数据集得到了位于研究区域及附近地区的8个永久性站点的记录的补充。站之间的间距大约为25-30 km。结果，获得了高质量的本地，区域和远程地震事件的记录。我们描述了该项目的目的和动机，台站的部署程序，以及临时地震台阵和永久台站的特征。此外，本文包括对重要问题的描述，例如：数据传输设置，状态监视系统，数据质量控制，站下方的近地表地质结构以及相关的现场影响等。特别注意了传感器的正确方向验证。将使用几种地震解释方法对获得的数据集进行建模，包括分析地震各向异性参数，目的是扩展有关岩石圈和亚岩石圈以下结构以及研究区域的构造演化的知识。
