Pilot whales Y-400 and Y-404 Location Update (June 29th, 2011)

June 29th, 2011

The whale appears to have found something of interest at depth off the eastern tip of Cuba.  Recently, he has begun to increase the number of dives he is making to 600m-900m.  Overall, 70% of his dives are less than 50m deep, and about 5% of dives are to 200-400m, with very occasional dives of 1,000m-1,500m.  About a third of his dives are of 5 min-15 min duration, with a few dives to >40 min.

May 22nd, 2011

Y-400 and Y-404 continue to remain together, and are now somewhere off the Blake Plateau (approximately 700 miles east of Charleston South Carolina) which is reasonable habitat for pilot whales. They have been making dives that are mostly less than 50 m deep, but some are to 100-200 m. Most dives are of 5-20 min duration, but occasional dives have been recorded as lasting more than 30 min but less than 40 min.
