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 –

    At 10:35 a.m. I heard J pod calls on the Lime Kiln Hps. J pod came up island, several close to shore echolocating and vocalizing a bit. There was a large group about 1/2 mile off shore in a resting pattern. That group was completely quiet. They had all passed by Lime Kiln lighthouse by 11:30a.m.
    Those first few recordings are J pod. The rest all sound to be L pod calls.

    Hey Scott, I learned that two L pod whales (based on their calls) showed up coming south past the lighthouse, while the rest of those L pod whales were still at Seabird coming in.
