Calls were at the rubbing beach (Voice Note by Robyn, identified the I15s). The N23 call could have been the A12s imitating this I15 call (N23), check notes for whales identified that day. There were a total of 10 calls identified; N4 (30%) and N23 (70%). Lots of rubbing behaviour heard throughout the recording.

There was one discrete call emitted by the northern residents while beach rubbing at 16:29 (N8), the rest were at Cracroft Point. Majority of calls were N4 (25%), N1 (23%), N2 (23%), N16 (15%), N10 (8%), and N9 (6%) with a total of 48 calls.

Quiet Recordings (2004)

Tapes 230A to 250B recorded by Orcalab in 2004 were analyzed for relatively quiet and loud ambient sound levels for computation by UVIC's Orchive program. This will allow researchers to organize and sample the large database of information for future studies.
