Whistle

J pod calls and whistles were heard by listening humans and computers tonight on the hydrophones at the Port Townsend Marine Science Center. Jeanne Hyde first reported them at 19:37, beating the automated detector by a full 20 minutes. Meg McDonald reported them at 20:39 and the final automated detections were at 20:58. Jeanne said the last faint calls she heard were at 20:59. So the vocal session lasted about 1 hour 22 minutes.

The automated recordings (below) contained predominantly S2 calls, some great whistles, and some high frequency buzzes. It was also noteworthy that calls were heard over clattering ship noise at 20:11, possibly the 20:00 departure of the Chetzemoka ferry from Port Townsend.
