with water temperatures varying with ambient air temperature. The major 
events of the experiment and the cumulative time at the end of each run 
are summarized in Table 2. 
Table 3 gives the data collection schedule within each 5-hour run. 
During the first 5 hours when the runs varied in length, the same data 
were collected, with the schedule depending on the length of the run.
