Passive acoustic monitoring data recorded by recorder SV1012 at mooring AWI248-3 in the Weddell Sea, Southern Ocean, in 2019/2020@en

Passive acoustic monitoring (PAM) data were collected by recorder SV1012 of type Sono.Vault (manufactured by develogic GmbH, Hamburg, Germany) at 65.9688° S, 12.2307° W, mooring AWI248-3, in the Weddell Sea, Atlantic sector of the Southern Ocean. During a deployment period from January 2019 to March 2022, passive acoustic data were collected from January 2019 to April 2020 (recording period) by SV1012 as part of the Hybrid Antarctic Float Observing System (HAFOS) in the Weddell Sea. The recorder was moored at 350 m depth and scheduled to record continuously at a sample rate of 24,000 Hz. Further details about the data acquisition and processing of this data set can be found in the accompanying metadata file (see Additional metadata) as well as the data processing report (see Data Processing Report). Passive acoustic data archived here represent data processing Level 1+, according to the standards defined in the associated Standard Operation Procedure (SOP) Glossary (Thomisch et al. 2023a). Further information on data processing with regard to data preparation and standardization can be found in the associated SOP Part 1: Data preparation and standardization (Thomisch et al. 2023b).被动声学监测（Passive Acoustic Monitoring，PAM）数据由德国汉堡develogic GmbH公司生产的Sono.Vault型SV1012记录仪采集，采集点位位于南大洋大西洋扇区威德尔海的AWI248-3锚系处，坐标为南纬65.9688°、西经12.2307°。该锚系的部署时段为2019年1月至2022年3月，其中SV1012于2019年1月至2020年4月（记录时段）作为威德尔海混合南极浮标观测系统（Hybrid Antarctic Float Observing System，HAFOS）的组成部分，采集被动声学数据。该记录仪布放水深为350米，设定采样率为24000 Hz并持续录制。本数据集的数据采集与处理的更多细节，可参阅配套元数据文件（详见附加元数据）及数据处理报告（详见数据处理报告）。此处归档的被动声学数据为经处理的1+级数据，符合相关标准操作程序（Standard Operation Procedure，SOP）术语表（Thomisch等，2023a）中规定的标准。有关数据准备与标准化环节的数据处理的更多信息，可参阅配套的SOP第一部分：数据准备与标准化（Thomisch等，2023b）。
