Sei whale:

Date/time (local)	Occurrence	Latitude	Longitude	Notes
03/30/21 17:25:11	Detected	42.4869	-70.4124	Doublets and singlets in P6-9.
03/30/21 18:40:11	Detected	42.4915	-70.4088	Doublet in P9 and possible singlet in P7.
03/30/21 19:25:11	Detected	42.4918	-70.4147	Doublets and singlets throughout the period, they are clear but unclassified. There are also classified upcalls throughout the period, I think these are RW but there’s also been a lot of upcalls bouts in the recent HW song and these could also be fragments of that.
