This record represents the Atlantic cod sound production detected from raw passive acoustic data. All acoustic data were processed using the automatic grunt detector and recogniser for Atlantic cod. This method uses a two-stage hypothesis testing algorithm that includes detecting and recognizing all grunt-like sounds. Detector output was manually verified, and false positives are removed. These data were recorded at SanctSound Site SB01_01 between November 12, 2018 and January 28, 2019.
