07:01 PDT Superb sounds!!
Good morning everyone! After as busy night, during which the I15s, A30s & A36s came back into Johnstone Strait on the flooding tide, we're hearing echolocation and I15 calls close to the Critical Point hydrophone. "A" calls are there too, so we think all 3 groups are probably still together, now in Robson Bight. There is no boat noise, so we're sent an alert.

12:13 PDT Orcas (may be) approaching cameras.
the a36s are approaching CP. Will be on CH. B

13:28 PDT Distant calls audible.
The A36s are travelling north through Blackney Pass while the i15s and the A30s are moving west along Vancouver Island.

15:48 PDT Superb sounds!!
The lovely chorus we've been listening to for the last while is coming from the A30s & I15s via the Critical Point hydrophone... they are in Robson Bight. We're also hearing the A36s, occasionally, in Blackfish Sound.
