12/02/19 00:55:24Possibly detected34.1098-119.7742Lots of faint HF tones here - several look like possible humpback signals (ie panels 14&15)
12/02/19 01:55:24Detected34.1098-119.7742tones here louder & more smooth than previously, some repeating signals (ie 100 Hz upsweeps in panels 9&10)
12/02/19 02:55:24Possibly detected34.1098-119.7742Sounds here less patterned than previous panel but still loud & several smooth enough to be convincingly biological

12/02/19 00:10:2434.1098-119.7742Strange straight tone at 400 Hz in panel 15
12/02/19 00:55:2434.1098-119.7742Lots of faint HF tones here - several look like possible humpback signals (ie panels 14&15)
12/02/19 01:55:2434.1098-119.7742tones here louder & more smooth than previously, some repeating signals (ie 100 Hz upsweeps in panels 9&10)
12/02/19 02:55:2434.1098-119.7742Sounds here less patterned than previous panel but still loud & several smooth enough to be convincingly biological
12/02/19 05:25:2434.1098-119.7742HF tones in panels 11&12 look too ragged to be biological, also very faint
12/02/19 06:25:2434.1098-119.7742Interesting LF tone in panel 4
12/02/19 07:25:2434.1098-119.7742Sporadic HF tones very jagged, likely not biological
12/02/19 07:40:2434.1098-119.7742Panels 15-16 have faint HF signals but very ragged & not convincingly biological
12/02/19 07:55:2434.1098-119.7742Continue faint, sporadic, jagged HF tones
12/02/19 08:10:2434.1098-119.7742Jagged, faint HF tones likely background noise & not biological
12/02/19 08:55:2434.1098-119.7742Strange repetitive 200Hz flat tone here, not sure what it is but not convincingly biological
12/02/19 13:40:2434.1098-119.7742Possible upsweep in panel 11 but kind of faint & jagged, surrounded by background noise tracks so not very convincing
12/02/19 15:25:2434.1098-119.7742Weird flat signal at 200 Hz in panel 9, part of background?
12/02/19 16:10:2434.1098-119.7742Possible faint blue downsweep in panel 16 but kind of short and kind of ragged, so not super convincing
12/02/19 16:25:2434.1098-119.7742lots of sporadic sounds here
12/02/19 16:55:2434.1098-119.7742lots of faint, short, sporadic tones here, nothing structured enough to be convincingly biological
12/02/19 17:10:2434.1098-119.7742continue sporadic tones
12/02/19 17:55:2434.1098-119.7742More faint, sporadic, short tones
12/02/19 18:55:2434.1098-119.7742Lots of sporadic, short, faint tones between 100-200Hz
12/02/19 19:10:2434.1098-119.7742Lots of sporadic, short, faint tones between 100-200Hz
12/02/19 19:55:2434.1098-119.7742Lots of sporadic, short, faint tones between 100-200Hz
12/02/19 20:10:2434.1098-119.7742100-200 Hz starting to seem pretty regular in pattern but all signals very short and pretty faint, not entirely convinced yet it's humpback
12/02/19 20:55:2434.1098-119.7742Continue patterned, short faint tone around 100/200 Hz; later lots of jagged HF tones indicative of background noise
12/02/19 21:55:2434.1098-119.7742Really strange HF signal in panel 15, jagged like surrounding background noise but much stronger
12/02/19 22:10:2434.1098-119.7742Another weird HF signal in panel 2, still looks very ragged but much stronger than typical background noise
12/02/19 22:40:2434.1098-119.7742Downsweep-shaped signal in panel 16 could be humpback, but fairly short & isolated, surrounding background noise also makes it less convincing
