Acoustic presence data on Antarctic blue whales (Balaenoptera musculus intermedia) were obtained from passive acoustic monitoring (PAM) data collected at 63°59.56' S and 00°02.65' W, mooring AWI229-09, recorder SV1000, between December 2010 and June 2011. The passive acoustic recorder was of type Sono.Vault (manufactured by develogic GmbH, Hamburg, Germany) and attached to oceanographic deep-sea mooring AWI229-09 of the Hybrid Antarctic Float Observation System (HAFOS). It was deployed from December 2010 to December 2012, moored at a depth of 969 m and recorded continuously at a sample rate of 5.333 Hz. After recovery, the passive acoustic data were prepared for further analysis following the Standard Operating Procedures (SOP) for PAM data collected by the Ocean Acoustics Group of AWI according to Thomisch et al. (2023a, regarding definitions and terminology) and Thomisch et al. (2023b, with regard to data preparation procedures). Daily acoustic presence of Antarctic blue whales was assessed based on ...
