Hello all,

This week’s temperature data has continued to show us that the thermocline position is steadily moving downward. Last week, we saw the thermocline starting at slightly above 40 meters where as this week we see it starting at just below 60 meters. The thermocline does not appear to be as strong as it had been in the past weeks. As far as the glider is concerned, these changes in the thermocline will not reflect in a change in the flight pattern. Below is a plot of this weeks temperature data.

Currently, we are constructing a trans-Atlantic contour plot using the data from RU27’s CTD casts throughout her journey. We are trying to find a way to insert this data into Google Earth in a 3d visual model. We recently came across Google Earth 5 and have high hopes that it will be able to support our massive contour plot. We will keep you updated weekly on the changes in the thermocline position and strength as we strive to create our 3d model.
