Dawn calls & clicks at Lime Kiln

2011/07/03 in Acoustic analysis, Lime Kiln State Park, Network news, Orcasound lab, southern resident

Lots of great SRKW calls (S3s, S4s) and clicks were automatically detected and recorded this morning, primarily on the Lime Kiln hydrophones. A few very loud calls are hard for me to categorize, but sound like variations on S42. Any other interpretations? An example:

http://www.orcasound.net/wholistener/lk/detections/raw/2011/07/03/PKTAveDb_97_07_03_2011_06_43_54.mp3

The only auto-detection at Orcasound (5km north of Lime Kiln) was a series of echolocation clicks 6:52, so it’s not clear what direction they were headed. However, John Boyd just noted on Facebook that there were whales at Open Bay (south end of Henry Island) at 11:00.

Computers beat human listeners at dawn

2011/06/22 in Acoustic analysis, Lime Kiln State Park, Network news, Orcasound lab, southern resident

Lots of whistles and calls (S1, S16) were detected by the WhoListener program this morning, first at Lime Kiln from 6:08-6:19, then at Orcasound (5 km north) from 7:47-7:52. Seems like some of the southern residents (J and K pod) are working the west side of San Juan Island, as members of both pods were observed and/or heard heading north towards and/or up through Haro Strait last night.

Did they double back and then go north again this morning or were they really (~9 hours?) spread out?

Here are all the auto-detections:

L pod returns calling on hydrophones

2011/06/10 in Acoustic analysis, Lime Kiln State Park, Orcasound lab, southern resident

The most common call used by L pod was automatically detected and heard by humans today on the Orcasound and Lime Kiln hydrophones. An S4 and some S7 calls were first detected at Lime Kiln around 11:20. (Could there be some J pod members in the neighborhood?) Then many S19 calls were recorded first at Orcasound and later at Lime Kiln. Perhaps L pod is traveling south along the west side of San Juan Island, after a long absence (last sighted in the Salish Sea on May 30)?

Detections as of 13:30 on 6/10/11 –

J pod whistles past Port Townsend

2011/05/13 in Acoustic analysis, Network news, Port Townsend Marine Science Center, southern resident

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.

Echoes of oldest J pod male Ruffles J1

As J pod re-entered the Salish Sea yesterday and their favorite S1 call was heard for the first time on the live hydrophones in Neah Bay, I found myself hoping that J1 or Ruffles was with them. Is there still a chance that the old man will return this year? Has he been alone or lost in some outer bay of Vancouver Island, like Luna’s uncle Orcan may have been, all winter long?

Almost 1.5 years ago, in the 24 hours prior to noon 01/27/10, the oldest male southern resident whale known as J1 or Ruffles was twice heard calling out as he swam along the west side of San Juan Island. Through the live underwater microphones of http://orcasound.net J1 was recorded making long, repetitive sequences of relatively rare calls.

There is little evidence that other members his family, J pod, were nearby.  The recordings only include consecutive calls with similar amplitudes, suggesting that only J1 was signaling (there was no response from an obviously distinct distance).  Calls are commonly heard on the live hydrophones when orcas are within a range of 5-10 kilometers.  Visual scans by Jeanne Hyde and other observers in the Islands also suggested that J1 was separated from the rest of his pod by more than a few kilometers.

Was this degree of separation atypical, or is this a common occurrence that we have not observed? Last February Candice Calloway of the Center for Whale Research wrote “He often swims alone, and can be miles away from the rest of his family…”

These acoustic events were also unusual because the repeated calls (S42 and S10) are rarely heard.  It’s also highly unusual to hear the same call repeated over and over again.  It’s noteworthy that the most common J pod calls S1 and S4 were not interspersed with the S42 and S10 calls.

Further analysis of these sound files is warranted, along with consideration of the sequence of events preceding the 2010-2011 winter disappearance of J1. You can lend a hand by contributing to this public Google spreadsheet of the J1 location and call chronologies.

We’ll keep our fingers crossed that he’ll make a surprise return this spring, but odds are that we should all work on our tributes to J1.  He still has much to teach us.

First recording of J pod off Neah Bay

2011/05/09 in Acoustic analysis, Neah Bay, Network news, southern resident

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 orcasound.net audio streams:

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.

J pod and L87 call on Lime Kiln hydrophones

2011/03/06 in Acoustic analysis, Lime Kiln State Park, southern resident

Today J pod (and L87) came in through Baynes Channel and traveled north up Haro Strait (based on Ron Bates report to Center for Whale Research mentioned on Orca Network Facebook page. The whales made some clear calls and clicks on the Lime Kiln hydrophones. Here is a sample recording of the calls which mainly were repeated S2s. Jeanne Hyde first heard a few calls at 10:50, but the following auto-detections only began at 11:28.

Orca acoustics featured at Port Townsend Marine Science Center

2011/02/04 in Network news, Port Townsend Marine Science Center

Chrissy McLean, Libby Palmer, and other innovators at the Port Townsend Marine Science Center have put together a very nice web page regarding killer whale communication. It features the live hydrophones, but also has an embedded recording and discussion of both their exhibits and boat-based studies in which they’ve participated.

Check it out: http://www.ptmsc.org/orca_communication.html

And here’s a current snap shot for the record.
