Right whale:

Date/time (local)OccurrenceLatitudeLongitudeNotes
07/01/23 23:14:52Possibly detected47.6658-63.5616One classified RW upcall in P9, but although it is mid-amplitude (which distinguishes it from nearby background noise), it has an artifact that distorts its shape and makes it difficult to tell whether it is a genuine right whale call. However, there is a second call in the same panel that, although unclassified, is high amplitude and has a tell-tale upcall shape, indicating likely right whale presence.

Date/time (local)LatitudeLongitudeNotes
07/01/23 05:29:5247.6941-63.7210Possible RW upcall (unclassified) in P4; it is mid-amplitude, well isolated, and has a good, upsweeping shape.
07/01/23 05:44:5247.6933-63.7196Two classified RW upcalls in P9 & 11, however, they are both very low amplitude, short-duration, and have small artifacts, so neither has a very convincing shape, which makes it difficult to tell whether they are genuine right whale calls.
07/01/23 14:29:5247.6977-63.6544One classified RW upcall in P3, however, it is very short-duration and does not have a convincing shape, so it is difficult to tell whether it could be a genuine right whale call.
07/01/23 18:14:5247.6788-63.6126One classified RW upcall in P10, however, it is low amplitude, short-duration, lacks a convincing shape, and looks likely to just be attributable to background noise.
07/01/23 22:14:5247.6687-63.5702One classified RW upcall in P15, however, it has a prominent artifact, so it is difficult to tell if its shape is truly indicative of a right whale. There is another possible unclassified call in P14, but it is very low amplitude and short- duration, so could potentially just be attributable to background noise.
