Distant calls audible. We did not mention earlier, but the I15s and at least some of the I31s met with the A30s in Blackfish Sound around 1:12pm. The orcas entered Johnstone Strait around 3:45pm. The A30s and at least some of the I15s milled at Cracroft Point, while some of the I15s and I31s continued east. We were able to watch the A30s and I15s for several hours as they foraged on our Cracroft Point camera. We also had some I11 "ish" calls at Cracroft Point, but we are unable to confirm if they were present. Megan at Cracroft Point reported at 4:23pm that there was a group of orcas mid-strait around Kaikash Creek, we believe these were some of the I15s and I31s as we could hear them independently on the Critical Point hydrophone. Near the slack tide, The A30s and some of the I15s grouped up and began to point north towards Blackney Pass. We started to hear louder calls on our Parson Island hydrophone, and at 6:43pm we spotted black fins. Most of the orcas travelled on the far side of Blackney Pass. There was some mixing of groups but the A30's generally lead the way, with the I15s and the I31s following shortly behind them. The current turned to ebb at 7:06pm and aided the orcas travels through Blackney Pass. They quickly cleared our view to the north at 7:20pm. We listened to their calls become more distant in Blackfish Sound; but they never completely disappeared. We noticed the calls start to get louder again at 8:46pm as they aimed towards Blackney Pass once again. The orcas entered the pass near Flower Island at 9:04pm. The I31s were first, followed by the I15s and then the A30s. It was very dark, but we could hear blows spread from the middle of the pass all the way to the opposite shore. They fought the ebbing current until 9:36pm. They made it to Harbledown Island before turning back to the north, and made quick progress back to Blackfish Sound. We heard the last blows in Blackney Pass at 9:40pm and we are still hearing their calls in Blackfish Sound. Whew. Maybe they will try again?  Dylan and Suzie 24 Aug 2017 22:41:51 PDT Superb sounds!! The orcas came just through Blackney Pass and are now heading into Johnstone Strait. You can rewatch it on orcalab base camera answer sea Ion camera or follow live on the Cracroft Point camera! http://explore.org/live-cams/player/orcalab-cracroft-point-surface Lab  24 Aug 2017 15:43:29 PDT Distant calls audible. A30 calls in Blackfish Sound! OrcaLab 24 Aug 2017 15:09:16 PDT No calls but orcas nearby A30s slowly heading through Blackney Pass south. Check out explore to watch them live! Orca Lab 24 Aug 2017 12:38:18 PDT No calls but orcas nearby There are no calls at the moment, but we've received reports that the A30's are headed into Blackney from the North. Orca Lab 24 Aug 2017 12:14:02 PDT No calls but orcas nearby The A30s are currently in Blackfish Sound, looking sleepy, and are slowly moving back towards Blackney Pass. Meanwhile, orcas have been sighted heading east from Malcom Point, so the afternoon could get busy again! Lab  24 Aug 2017 11:12:49 PDT Orcas near mics. After slowly travelling through Johnstone Strait from the east, the A30s have just passed Cracroft Point and are currently very vocal: heading into Blackney Pass from the east!  Suzie 24 Aug 2017 07:55:54 PDT Orcas near mics. A1 calls on Critical Point hydrophone! It sounds like it was indeed the A30s who snuck past us in the night. OL 24 Aug 2017 05:40:10 PDT No orcas present. Late yesterday evening at 9:20pm, the A30s tried to work against the ebbing tide and travel south through Blackney Pass. As updated earlier, we could hear their blows in the pass, but they did not make it far before turning back to the north. We continued to hear their vocalizations become more distant on the Flower Island hydrophone until the last call was heard at 10:21pm. We heard nothing further until 12:30am when we heard a single A1 call, on what we think was the Flower Island hydrophone. Shortly after, at 12:56am, we could hear blows outside of the lab heading to the south with the flooding tide. The orcas were completely silent the whole way through and cleared towards the Strait at 1:15am. We cannot say for sure that they were the A30s, but it is currently our best guess! We will see what clues the morning brings. Dylan and Max 24 Aug 2017 04:45:40 PDT
