Marlon, Scott McL., John C., and other friends in Halifax ------

We have a class of undergrads here at Rutgers that is just having a great time with this. They are scouring the web for datasets, satellite images, model forecasts, altimeter maps, ice maps, wave forecasts, etc, etc. Some are working on the path planning. Others on the conditions in the landing zone. Just like the Stommel race, but this time the race is against the clock. Dave Aragon, our glider electronics tech, has given us 35 more days of flight time (starting today) before we have to hang it up. We think he's built in a safety factor, but he's certainly too smart to tell us what it is.

So RU15 has to stop surfing the Gulf Stream and looping around in the warm core rings and head for a home port. Do you have a similar group of students that we could set up a skype or other video conference with?
Our students would like to talk to yours about the sea conditions, ice conditions, currents, weather, and everything else that comes up when you are searching for a home port. I-COOL edu at its best.

We keep seeing the wave forecasts calling for 7 to 13 foot seas offshore of Halifax. You know from the HyCODE days that waves like that are not something we are used to. Maybe with your help we can bring this glider home and snag a Dalhousie sticker for the hull in the process.

Hope to see you all in a few weeks!

Path Home

Here is the satellite image from today. The red dots are where we are going to send the glider.

This is the path on google earth

Marlon, we are on our way!!!

Marlon - Good news. RU15 just flew out of the warm core ring. Currents are down to below 20 cm/sec, and direction has switched. We can fly where we want to for the first time in a week! We are heading northwest into the next eddy to the north.

We'll try to follow a path like this. You can click on the image to see it bigger. We'll head north into this smaller eddy, shoot around the top to the east, stay in the cold water till we get the small eddy by 63W that will get us up to the shelf break. From there, we cross the shelf towards Halifax, a standard coastal endurance line with the altimeter turned back on.

Hope to see you up there in about 3-4 weeks.
Dave wants lots of extra power in the batteries when this one comes home.

Almost out

Spinning around and out. Almost there. Flying perpendicular to the current.

Current speeds are down to 50 cm/sec

Temperatures also decreasing to 13C
