| 06/09/22 03:40:41 | 41.0613 | -70.8324 | Possible HW vocalizations in P10 and 12 but the pitch tracks are short and could easily be noise. |
| 06/09/22 04:40:41 | 41.0613 | -70.8324 | Possible HW vocalization at the beginning of P13? |
| 06/09/22 10:25:41 | 41.0613 | -70.8324 | Possible HW social sounds in P8? They could be nonbiological. One faint LF downsweep in P16, source
unknown. |
| 06/09/22 15:10:41 | 41.0613 | -70.8324 | Possible HW downsweep in P14? |
| 06/09/22 18:25:41 | 41.0613 | -70.8324 | One LF downsweep in P4, source unknown. |
| 06/09/22 18:40:41 | 41.0613 | -70.8324 | There are a lot of very short LF downsweeps in P12-14, one of which is classified as SW. There’s another
short downsweep just before it but they’re different amplitudes and both very short. Source unknown.
Also a possible HW upsweep in P15 but the pitch track is jagged and could be noise. |
| 06/09/22 18:55:41 | 41.0613 | -70.8324 | Loud short LF downsweeps throughout this period, source unknown. |
| 06/09/22 19:10:41 | 41.0613 | -70.8324 | There are some LF downsweeps and other spurious pitch tracks in P2, difficult to tell what is biological or
not. |
| 06/09/22 19:25:41 | 41.0613 | -70.8324 | One loud, straight LF downsweep in P10, source unknown. |
| 06/09/22 20:10:41 | 41.0613 | -70.8324 | A few loud, straight LF downsweeps throughout this period but especially in P9-10. Source unknown. |
| 06/09/22 20:40:41 | 41.0613 | -70.8324 | Short LF downsweeps throughout this period, source unknown.
Good example of these random downsweeps that have been observed periodically on different platforms. |
