Marine mammal baseline, Johan Castberg ...
Acoustic data were recorded at the Johan Castberg field in the southern Barents Sea at three locations from October 2018 until June 2019 to assess the presence of marine mammals and characterise the underwater soundscape. The marine mammal analysis was focused on two stations (PAMEast and PAMNorth)...
