Passive acoustic monitoring (PAM) data were collected by recorder SV1019 of type Sono.Vault (manufactured by develogic GmbH, Hamburg, Germany) at 20.9757 ° S, 5.9845 ° E, mooring AWI247-3, in the eastern Atlantic Ocean off Namibia. During a deployment period from November 2012 to November 2014, passive acoustic data were collected from November 2012 to May 2013 (recording period) by SV1019 off Namibia. The recorder was moored at 736 m depth and scheduled to record continuously at a sample rate of 5,333 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).
