2/12/2018all dayTop end of Johnstone Strait?Helena+Jared FB report re first images of Yukusam. "Lisa had been listening to and recording this whale from Orcalab for several days." Comments include: "Linda Nichol fantastic. So how deep might this animal have been diving? Sounds like he went down for ...almost an hour at a time? So must have been very deep and/or some very profitable feeding way down there.
Jared Towers The deepest part of Johnstone strait is just over 500 metres and the dive durations I could document were between 20 and 40 mins."

22
3/24/20189:00ONC SoG hydrophones?Estimated time Yukusam swam over ONC's SoG hydrophones: 365 km / (7 days, 5 hours) 365/173 = 2.17 km/hr mean speed; [Distances from last hearing to: SOG hydrophones = 294 km; S end Lummi = 365 km] => 32 hours before seen by Lummis = 3/24/18 9 a.m.
23
3/25/201817:00Off Carter Pt, So. end of Lummi2.1Randingo Kinley via Nickolaus Dee Lewis; Lummi fisherman sighting; time approximated based on "late afternoon/early evening" (not confirmed with photos)
24
3/26/201818:00ONC SoG hydrophones?Estimated time Yukusam swam over ONC's SoG hydrophones northbound to Nanaimo: 72 km from S end Lummi to SoG Hps / 2.8 km/hr = ~25 hrs after seen by Lummis = 3/26/18 18:00
25
3/27/201811:45ONC SoG hydrophones?Very faint clicks on ONC hydrophone? (11:45 fainter than ~12:00?) => detection range of 50km?! or a boat.

3/31/201812:00?East Point, Saturna Is., BC?107 km Piper's Lagoon to Turn Point via East Point in 96 hours = ~1km/hr => foraging more? Or he went nonlinearly?
38
3/31/201816:00?South Pender Is., BC
Monika Wieland email: "Someone on shore reported seeing him from South Pender in Boundary Pass shortly before he was picked up by the whale watch vessels, so I agree that's the way he came down."
39
3/31/201816:30Offshore of Blunden Islet, BCJeff Friedman email: "I am almost certain he came down Boundary Pass. Our first sighting, which would have been at approximately 4:30 PM, was from 1 - 2 miles away. We saw his blows and then fluke. We were crossing Boundary, between the north side ot Stuart and South Pender. We was at our northeast and we went to get a better look for his next surfacing. At that point he appeared to be well offshore of Blunden Islet, on the southeast side of South Pender, traveling directly toward Turn Point.

We waited for 25 minutes, then left to catch up with J pod along the North Pender bluffs. About an hour later (rough guess) we had visual at Turn Point."
