Cook course set for the weekend

Friday, April 16th, 2010

Its a slower pace of life with the deep thermal glider. Last year Scarlet called every 8 hours, and since she was a surface glider, we were always responding to the combination of weather-forced and internal changes in the surface ocean. This deep glider slows the pace down even more than a surface glider. We are alternating between 7-8 hour single-yo (one downcast & one upcast) missions and 14-15 hour double-yo missions as Tod at Teledyne Webb continues his tuning of the flight characteristics. Once Tod has the flight parameters squared away, we'll spend some time on the sensor data. Once we settle in on a vertical speed profile, we want to compare a couple of CTD upcasts and downcasts on a double yo mission. All this can be accomplished while sitting off the CaRA testbed in Puerto Rico and St. Thomas, just like RU26. But RU26 is being recovered by our CaRA partners at the University of Puerto Rico Mayaguez. We want Cook in position on the western side of the 26.5 N transect at the beginning of summer. That means tuning as we go. Amelia & Kyle already started the path planning process, switching from last week's blue route to this week's green route based on the U. Colorado satellite Sea Surface Height (SSH) data seen below. John is setting up the NASA global Sea Surface Temperature (SST) maps, and the Navy HYCOM forecast model, for the google earth glider navigation interface. We'll soon post instructions on how you can download the google earth kmz files to follow along.
