All times are Alaska local time

Pitch tracks shown for calls 11 dB above background or higher

Pitch tracks colored according to amplitude: cooler colors are quieter, warmer colors are louder

If a pitch track has been successfully classified, the call type and Mahalanobis distance will be reported below the call. Call types are as follows:

• Bowhead whale (various calls): call types 80-85
• Fin whale 20-Hz pulse: call type 1
• Humpback whale (various calls): call types 5-12
• Right whale upcall: call types 105-108
• Killer whale (various calls): call types 30-34
• Beluga (various calls): call types 50-55
• Walrus bell: call types 20-21
• Bearded seal short downsweep: call type 70

Dashed vertical lines indicate the following DMON events:

• MUTEON: the hydrophone is muted to assess system noise and to provide a time mark in the audio recording
• MUTEOFF: the hydrophone is unmuted and normal recording has resumed
• ADDET_OFF: a maximum of 8 KB of pitch track data per hour is transmitted by the glider. The ADDET_OFF message indicates that this limit has been reached.
• ADDET_ON: transmission of pitch track data has resumed
• $ADRUN, 0: the glider has reached the surface and will begin data transmission home, so pitch tracking is terminated
• $ADRUN, 3: the glider has finished data transmission at the surface and is initiating a dive, so pitch tracking has resumed
