| Summary: | Passive acoustic monitoring (PAM) data were collected by recorder AU0086 of type AURAL (Autonomous Underwater Recorder for Acoustic Listening (AURAL; Model 2, Multi-Électronique) at 68.9957° S, 0.0028° E, mooring AWI232-9, in the Weddell Sea, Atlantic sector of the Southern Ocean. Passive acoustic data were collected from March 2008 to December 2010 by AU0086 as part of the Hybrid Antarctic Float Observing System (HAFOS) in the Weddell Sea. The recorder was moored at 206 m depth and scheduled to record at a duty cycle of 5 min per 4 h at a sample rate of 32,768 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).
