03/23/26 01:47:24Possibly detected42.9984-70.3745Marking fin as possibly detected based on P11-12
03/23/26 04:17:24Possibly detected42.9991-70.3931Marking fin as possibly detected based on P9-10. INI closer to ~10 and only two classified with a possible third unclassified in P10.
03/23/26 06:32:24Detected43.0025-70.4031Marking fin as possibly detected based on P7-8
03/23/26 09:17:24Possibly detected43.0027-70.4165Marking fin as possibly detected based on P5-6. It is mixed in with a lot of LF background noise so do not feel confident marking as detected, there are other strong pulses with harmonics throughout the summary.
03/23/26 10:17:24Possibly detected42.9966-70.4223Marking fin as possibly detected based on P4-5.
03/23/26 10:32:24Possibly detected42.9966-70.4223Marking fin as possibly detected based on P1 and other strong pulses with harmonics throughout summary. It does look like there is LF background noise in P1.
03/23/26 14:17:24Possibly detected42.9713-70.4297Marking fin as possibly detected based on P8-9.
03/23/26 16:02:24Possibly detected42.9615-70.4205Marking fin as possibly detected based on P2-3. Looks like harmonics, but could be background noise.

Humpback whale:

Date/time (local)OccurrenceLatitudeLongitudeNotes
03/23/26 02:47:24Possibly detected42.9997-70.3833Marking humpback as possibly detected based on P2-3. Could also be background noise but looks like repetitive MF downsweeps. Calls are low amplitude but it does look similar to repetitive downsweeps seen this season as part of humpback activity.
03/23/26 03:17:24Detected43.0003-70.3877Detected NARW in P7-8 look like they could be humpback. There is humpback throughout the summary, all classified and unclassified upsweeps seem to have a higher starting frequency. NARW in P7 looks like it's in an upsweep/downsweep pattern and NARW in P8 appear to be in a doublette upsweep pattern. There are higher frequency components to some of the upsweeps which can happen for either species. Marking as not detected for NARW but can see marking as possibly as well.
03/23/26 13:32:24Possibly detected42.9759-70.4337NARW in P13 looks like background noise. Context supports this so marking as not detected. Marking humpback as possibly detected based on P7-9. Patterned downsweeps look like humpback, but there is also a lot of background noise, most of it is LF but there is also some HF noise.
03/23/26 17:17:24Possibly detected42.9577-70.4077Marking humpback as possibly detected based on P13-14. Looks like patterned HF downsweeps, however there is a lot of background noise, most LF but some HF as well.
03/23/26 22:17:24Detected42.9607-70.3625Humpback song present in P1-P5. There is one marked NARW call in P1, similar amplitude than other upcalls below it and doesn't happen outside of song so making not detected.
