Here is the August 31 update from Jim at Driftbusters for 73 days a drift.  Some interesting results as the arrows from 30 and 35 N reverse thier drift and the arrows from 48N seem to be out pacing the others. 

Jim ran his computer model for July 31.  The arrows north of the Aluetians may have made it to shore already?  the others still have a long way to go but some are moving faster than others.   Thanks Jim.

Check back in a month for the next prediction.

So here is the prediction from Jim at Drift Busters that shows the arrows drift track after 12 days of being loosed from Healy.  We should be getting another update at the end of July, so check back to follow thier drift.

Well we made it.  The end of the line.  Healy did alot of pushing, leaving 2,000 miles of Pacific Ocean in its wake.... and 100 drift arrows.  Now we wait and see if and where the drifters will wash up and be reported.  Tomorrow we dock in Dutch Harbor (a day early) and the next day I get to fly home to my family.  The crew of Healy though has only begun their journey which will take them away from home for six months.

As we steam away the miles heading North, the temperature of the water and air are steadily dropping. Water temperature has averaged more than a degree of Celcius  for each degree of latitude.   No more chances for a swim call now.  Today another 10 drift arrows were loosed at  41N. 

Currently we are conducting some multibeam testing at 28.79N 159.89W on a deep sea feature that will allow for good testing. The next set of drift arrows will be loosed at around 30 N and then 36 N and then 3 degrees of latitude spacing thereafter with more concentrated around 45N.  The model run by Jim Ingraham predicts that arrows released around 45N may drift back to Seattle so I plan to "aim" more arrows toward Puget Sound.
