| Date/time (local) | Latitude | Longitude | Notes |
|---|
| 12/02/19 01:10:24 | 34.1098 | -119.7742 | Strange straight tone at 400 Hz in panel 15 |
| 12/02/19 01:55:24 | 34.1098 | -119.7742 | Lots of faint HF tones here - several look like possible humpback signals (ie
panels 14&15) |
| 12/02/19 02:55:24 | 34.1098 | -119.7742 | tones here louder & more smooth than previously, some repeating signals (ie
100 Hz upsweeps in panels 9&10) |
| 12/02/19 03:55:24 | 34.1098 | -119.7742 | Sounds here less patterned than previous panel but still loud & several smooth
enough to be convincingly biological |
| 12/02/19 06:25:24 | 34.1098 | -119.7742 | HF tones in panels 11&12 look too ragged to be biological, also very faint |
| 12/02/19 07:25:24 | 34.1098 | -119.7742 | Interesting LF tone in panel 4 |
| 12/02/19 08:25:24 | 34.1098 | -119.7742 | Sporadic HF tones very jagged, likely not biological |
| 12/02/19 08:40:24 | 34.1098 | -119.7742 | Panels 15-16 have faint HF signals but very ragged & not convincingly
biological |
| 12/02/19 08:55:24 | 34.1098 | -119.7742 | Continue faint, sporadic, jagged HF tones |
| 12/02/19 09:10:24 | 34.1098 | -119.7742 | Jagged, faint HF tones likely background noise & not biological |
| 12/02/19 09:55:24 | 34.1098 | -119.7742 | Strange repetitive 200Hz flat tone here, not sure what it is but not
convincingly biological |
| 12/02/19 14:40:24 | 34.1098 | -119.7742 | Possible upsweep in panel 11 but kind of faint & jagged, surrounded by
background noise tracks so not very convincing |
| 12/02/19 16:25:24 | 34.1098 | -119.7742 | Weird flat signal at 200 Hz in panel 9, part of background? |
| 12/02/19 17:10:24 | 34.1098 | -119.7742 | Possible faint blue downsweep in panel 16 but kind of short and kind of
ragged, so not super convincing |
| 12/02/19 17:25:24 | 34.1098 | -119.7742 | lots of sporadic sounds here |
| 12/02/19 17:55:24 | 34.1098 | -119.7742 | lots of faint, short, sporadic tones here, nothing structured enough to be
convincingly biological |
| 12/02/19 18:10:24 | 34.1098 | -119.7742 | continue sporadic tones |
| 12/02/19 18:55:24 | 34.1098 | -119.7742 | More faint, sporadic, short tones |
| 12/02/19 19:55:24 | 34.1098 | -119.7742 | Lots of sporadic, short, faint tones between 100-200Hz |
| 12/02/19 20:10:24 | 34.1098 | -119.7742 | Lots of sporadic, short, faint tones between 100-200Hz |
| 12/02/19 20:55:24 | 34.1098 | -119.7742 | Lots of sporadic, short, faint tones between 100-200Hz |
| 12/02/19 21:10:24 | 34.1098 | -119.7742 | 100-200 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 21:55:24 | 34.1098 | -119.7742 | Continue patterned, short faint tone around 100/200 Hz; later lots of jagged
HF tones indicative of background noise |
| 12/02/19 22:55:24 | 34.1098 | -119.7742 | Really strange HF signal in panel 15, jagged like surrounding background noise
but much stronger |
| 12/02/19 23:10:24 | 34.1098 | -119.7742 | Another weird HF signal in panel 2, still looks very ragged but much stronger
than typical background noise |
| 12/02/19 23:40:24 | 34.1098 | -119.7742 | Downsweep-shaped signal in panel 16 could be humpback, but fairly short &
isolated, surrounding background noise also makes it less convincing |
