Again, thermometers were placed around the tank to measure the temperature gradient generated. Two sets of four sensors each were placed at similar heights 50 degrees apart, to ideally record both sides of a single eddy. See the schematic below.
As in the Hadley cell experiment, a temperature gradient was observed to have developed much more strongly at the bottom of the tank, due to the denser, colder water sinking downwards.
The 988.7 grams of ice were not replenished over the course of the experiment and took thirty minutes to fully melt. Assuming that the power outputted by the ice was equal to the heat transported by the eddies, the system could be described by the following equation:
