Encounter Summary:

I received a report from Spencer Domico at ~1300 that he had come across westbound killer whales 11 miles south of Discovery as he was headed to Port Angeles.
I left Victoria harbour on Mike 1 at 1330 as Spencer left the T085's at 48 16/123 17.8 traveling north. I re-spotted them at 1403 chasing a harbour porpoise (48 17.3/123 18.5). They caught it and consumed it within 2 minutes of me arriving.
They traveled northwest to the southwest corner of Constance Bank and then turned to the west. They were traveling west towards Pedder Bay at a steady 5 knots and doing ~6-minute dives. I watched them pass by a couple of harbour seals and did not observe any more predation. I ended the encounter at 1542 and returned to Victoria harbour.
