Acoustic event log of the 2013 Antarctic Blue Whale Voyage to the Southern Ocean
Progress Code: completed Statement: This dataset only contains acoustic events that were detected and analysed during the voyage. During periods when few sounds were present, all of the sounds were likely to be included in the acoustic event log. During periods when many sounds were detected, not al...

The acoustic tracking software stored all acquired bearings, and cross bearings in text files. During the 2013 Antarctic Blue Whale Voyage Acousticians noted all whale calls and other acoustic events that were detected during real-time monitoring in a Sonobuoy Event Log.
