Sei whale:

Date/time (local)	Occurrence	Latitude	Longitude	Notes
04/12/23 06:52:26	Possibly detected	40.8820	-71.1196	One faint classified singlet.
04/12/23 09:41:17	Possibly detected	40.8565	-71.1284	One possible faint classified singlet.
04/12/23 12:41:17	Possibly detected	40.8408	-71.1487	Possible classified singlet in P3 and other possible faint unclassified singlets in P11, 12, and 15 but they all look a bit steep for SW.
04/12/23 12:56:17	Possibly detected	40.8397	-71.1504	LF downsweeps in P11, 12, and 14 with two call type 17 classifications but they all look steep for SW.
04/12/23 17:41:17	Possibly detected	40.8185	-71.1671	Possible classified SW doublet in P4 but the pitch tracks are very short and faint.
04/12/23 21:11:17	Detected	40.7975	-71.1875	One classified doublet and three classified and unclassified singlets.
04/12/23 21:26:17	Possibly detected	40.7961	-71.1899	Two possible SW singlets with one classification in P2 and 5. A few possible RW upcalls with one classification in P9-11 but the classified upcall is a bit jagged and there’s also what looks like possible faint HW in P6 which makes me skeptical.
04/12/23 22:11:17	Detected	40.7918	-71.1970	One classified doublet and multiple classified and unclassified singlets.
04/12/23 22:26:17	Detected	40.7904	-71.1994	The same classified doublet from the previous period but also a few more classified and unclassified singlets. One classified RW upcall in P14 but it could be part of some faint HW song.
04/12/23 22:56:17	Possibly detected	40.7876	-71.2040	One possible SW singlet with call type 17.
