Humpback whale:

Date/time (local)OccurrenceLatitudeLongitudeNotes
07/21/26 00:06:16Possibly detected43.7528-67.68762 HW downsweeps in p2
07/21/26 00:51:16Possibly detected43.7513-67.6828p7, p15 two poss HW downsweeps.the one in p7 might be an artifact
07/21/26 02:06:16Possibly detected43.7493-67.6743at least four poss HW sounds
07/21/26 02:21:16Possibly detected43.7489-67.6725one downsweep in p6, lots of artifacts
07/21/26 18:36:16Possibly detected43.6818-67.5439P4-P6 has possible HW moans, there are some intermittent classified fin pulses however the moans stand out from the fin pulses as they are longer than a pulse and look more similar to HW social sounds so I am marking HW as possibly detected. I could also see marking HW as detected.
07/21/26 21:06:16Possibly detected43.6616-67.5191P8 has convincing HW downsweep and P2, P5 and P11 have other HW evidence, possible moans. Marking humpback as possibly detected. There is some LF noise, but the HW calls are isolated. Also one or two other LF sounds that could be HW, I could also see marking as detected.

07/21/26 21:21:1643.6592-67.5163P11, P12 and P15 have possible downsweeps/moan but with the other noise throughout for P11-p12 I am not convinced for HW. Leaving as not detected.
07/21/26 21:36:1643.6568-67.5134P6-P8 have LF noise that could be HW, but no obvious patterns and I am just not convinced enough to mark this as detected.
07/21/26 23:21:1643.6627-67.4996P10 has long possible HW moans but I am leaning towards LF noise. Marking as not detected.
