First recording of J pod off Neah Bay

Neah Bay hydrophone dock

Thanks to a call from Jon Scordino, marine mammal biologist for the Makah Tribe, we were able to record J pod vocalizations for the first time using a hydrophone deployed just inside the entrance to Neah Bay. Jon got some photos which should confirm or deny the acoustic inference of the pod identity.

Here are example clips made using the recording software in Neah Bay, as well as the raw recordings from the audio streams:

100 second clip with S1, S2, and S10 calls (and percussives?) —

Longer continuous recordings —

The only other time killer whales have been observed using this hydrophone was on 9/28/2008 at 23:00:00 — the approximate time when a human listener reported hearing calls. In both of these cases, however, the automatic detector was not triggered — although it may have done so during the loudest calls recorded today if I hadn’t over-ridden the system by manually recording through the WhoListener software.

    Awesome! Now I’ll have to put Neah Bay on my listening list!

  2. Awesome! I would love to put mics in a pod of Killers!

  3. Travel time to Lime Kiln might be around 15 hours, so listen to tomorrow (Tuesday) morning.

    @Stephen: Marla Holt did just that (with a suction cup) last year and will report on the results at the ASA meeting in Seattle this month.
