01/10/20 00:25:2434.1098-119.7742LF pulses classified as fin too sporadic
01/10/20 00:40:2434.1098-119.7742Pulse interval of LF signals classified as fin pretty sporadic, those that are consistent aren't right for typical fin (~45s)
01/10/20 00:55:2434.1098-119.7742Many faint & sporadic HF pulses
01/10/20 02:55:2434.1098-119.7742Fairly strong HF pulses in panel 15 but not patterned or long enough to suggest humpback
01/10/20 04:25:2434.1098-119.7742HF pulse in panel 15
01/10/20 04:55:2434.1098-119.7742Impulsive HF sweeps in panels 6, 10-11, 16 but not strong enough or patterned enough to be convincing for biological sound
01/10/20 05:25:2434.1098-119.7742Many faint chaotic HF tones, likely background noise
01/10/20 06:10:2434.1098-119.7742Continue faint HF chaotic signals indicative of background noise
01/10/20 07:25:2434.1098-119.7742Several flat LF tones around 25Hz but much too short to be very convincing for blue whale calls
01/10/20 07:40:2434.1098-119.7742Several flat LF tones around 25Hz but much too short to be very convincing for blue whale calls
01/10/20 07:55:2434.1098-119.7742Continue short flat & faint 25Hz tones
01/10/20 08:10:2434.1098-119.7742Panel 5 has strong LF downswept signal but seems too low to be very convincing for blue whale downsweep
01/10/20 09:55:2434.1098-119.7742Long strong flat 150Hz tone in panel 4
01/10/20 10:40:2434.1098-119.7742Several faint flat tones around 300Hz in panel 9
01/10/20 10:55:2434.1098-119.7742Panel 4 has strong flat tone around 200Hz
01/10/20 11:25:2434.1098-119.7742Slightly upswept signal at 55s in panel 11, could be humpback but isolated & surrounded by background noise, not strong enough to be convincing
01/10/20 12:25:2434.1098-119.7742Ragged fast downsweep around 300Hz in panel 12, could be biological but not strong or smooth enough to be very convincing
01/10/20 12:55:2434.1098-119.7742Mid frequency downsweep in panel 13, Hf downsweep in panel 14 both pretty short and faint
01/10/20 13:25:2434.1098-119.7742Hf signal in panel 13 looks too ragged to be convincing for biological sound
01/10/20 13:40:2434.1098-119.7742Interesting 1 kHz signals in panels 9&15
01/10/20 13:55:2434.1098-119.7742Several very short faint 1 kHz signals, not patterned
01/10/20 14:25:2434.1098-119.7742Background noise/vessel? Flat tones in panels 416, faint chaotic Hf signals in panel 13
01/10/20 23:25:2434.1098-119.7742Long 600hz upsweep in panel 13
01/10/20 23:55:2434.1098-119.7742Many faint 800hz pulses
