Passive acoustic monitoring data recorded by recorder SV1012 at mooring AWI245-3 in the Weddell Sea, Southern Ocean, in 2013

Passive acoustic monitoring (PAM) data were collected by recorder SV1012 of type Sono.Vault (manufactured by develogic GmbH, Hamburg, Germany) at 69.058° S, 17.3887° W, mooring AWI245-3, in the Weddell Sea, Atlantic sector of the Southern Ocean. During a deployment period from December 2012 to January 2017, passive acoustic data were collected from December 2012 to November 2013 (recording period) by SV1012 as part of the Hybrid Antarctic Float Observing System (HAFOS) in the Weddell Sea. The recorder was moored at 1065 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 2+ (see Data Processing Report), deviating from 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).
