Notes:

Date/time (local)LatitudeLongitudeNotes
08/16/19 01:19:4434.1111-119.7746More repetitive noise - short ~100-125 Hz pulses.
08/16/19 03:04:4434.1111-119.7746Repetitive ~100 Hz very short pulses - what are these?
08/16/19 03:19:4434.1111-119.7746More repetitive pulses at around 100 Hz
08/16/19 03:34:4434.1111-119.7746100 Hz pulse continues at fairly regular intervals
08/16/19 03:49:4434.1111-119.7746More 100 Hz pulses
08/16/19 04:19:4434.1111-119.7746Single LF tone in panel 4, but very short for B call. Single short upsweep 800-1000 Hz in panel 6.
08/16/19 04:34:4434.1111-119.7746Return of 100 Hz pulses. 4 pulses around 50 Hz in panel 4, possibly 40 Hz fin call but interval between calls is very short - way too rapid for 40 Hz
08/16/19 04:49:4434.1111-119.7746High frequency track in panel 13 doesnít look biological - ship noise?
08/16/19 05:04:4434.1111-119.7746Possible faint D call in panel 9 - too short. Higher calls all fairly faint and no pattern, so not convincing for humpback.
08/16/19 05:19:4434.1111-119.7746Higher frequency sounds faint and not patterned; likely anthropogenic. LF tone in panel 3 could be a B call but not very convincing. Also frequency doesn't seem right.
08/16/19 05:34:4434.1111-119.7746Noises all faint and not patterned, likely ship/background noise
08/16/19 05:49:4434.1111-119.7746Interesting down sweep in panel 6 but fairly faint and given surrounding background noise, not convinced of humpback presence. Contour too ragged.
08/16/19 06:19:4434.1111-119.7746Fairly loud pitch tracks in panels 4 & 14 but not sure itís biological - doesn't seem biological
08/16/19 06:34:4434.1111-119.7746Likely ship noise here
08/16/19 07:19:4434.1111-119.7746A few isolated rapid upsweeps
08/16/19 07:49:4434.1111-119.7746Panels 2, 9, & 10 have some clean, loud pitch tracks that might be humpback
08/16/19 08:19:4434.1111-119.7746Faint tracks in panel 7 donít seem biological
08/16/19 08:34:4434.1111-119.7746Rapid high-frequency sweeps in panels 6&7, likely not humpback given pattern of noise in panels 9&10.
08/16/19 08:49:4434.1111-119.7746Ship noise?
08/16/19 09:19:4434.1111-119.7746Sounds here are faint and not likely biological
08/16/19 09:34:4434.1111-119.7746Ship noise
08/16/19 09:49:4434.1111-119.7746Ship?
08/16/19 10:34:4434.1111-119.7746Interesting upswept sound in panel 5 between 50-100 Hz. Don't know anything biological in this area that would do that
08/16/19 10:49:4434.1111-119.7746Downsweep in panel 12 is a little high & short for blue whales, another in panel 15 very faint
08/16/19 11:04:4434.1111-119.7746Possible D call in panel 4 Not a great contour line though.
08/16/19 11:19:4434.1111-119.7746Long LF tone in panel 5 - not biological
08/16/19 11:34:4434.1111-119.7746Very short down sweeps in panels 10,14, & 16 - not convincing enough for blue whales
08/16/19 12:34:4434.1111-119.7746Singular loud, rapid sweep in panel 14? - too high for blue or fin.
08/16/19 13:04:4434.1111-119.7746Ship?
08/16/19 13:34:4434.1111-119.7746Ship?
08/16/19 13:49:4434.1111-119.7746Ship
08/16/19 14:04:4434.1111-119.7746What are the long tones in panel 6? Weird contours, but faint start: maybe not biological?
08/16/19 14:19:4434.1111-119.7746Ship - ? noise.
08/16/19 14:49:4434.1111-119.7746Ragged LF tone in panel 9 just below 50 Hz - too low/ragged for blue whale
08/16/19 15:19:4434.1111-119.7746Tones appear very mechanical
08/16/19 15:49:4434.1111-119.7746Long 150 Hz tone in panel 7 - non biological?
08/16/19 16:04:4434.1111-119.7746A few rapid sweeps but all very faint, could be background noise
08/16/19 17:04:4434.1111-119.7746Short D call in panel 3? - Too shore, if anything fin 40 Hz.
08/16/19 17:19:4434.1111-119.7746Long 150 Hz tone in panel 7 - not biological
08/16/19 18:04:4434.1111-119.7746Many rapid sweeps here - humpback?
08/16/19 18:19:4434.1111-119.7746More rapid sweeps but faint
08/16/19 18:49:4434.1111-119.7746Possible faint, short D call in panel 15? - Too faint and too short
08/16/19 19:04:4434.1111-119.7746Rapid upsweeps in panel 10?
08/16/19 20:34:4434.1111-119.7746Possible humpback upsweeps in panels 3&6 but fairly faint - too isolated.
08/16/19 20:49:4434.1111-119.7746100 Hz pulses & ragged upsweep in panel 16
08/16/19 21:04:4434.1111-119.7746100 Hz pulses, very faint LF tones in panels 10&11 - don't look very blue-like
08/16/19 21:34:4434.1111-119.7746Many tones around 125 Hz - non-biological
08/16/19 22:19:4434.1111-119.7746Is this humpback? No clear pattern but many varied sounds Seems a bit low frequency; more consistent with earlier LF pulses?
08/16/19 23:19:4434.1111-119.7746Is this humpbacks? - Seems too low for it. Anthropogenic?
