You may immediately notice some daily variations in parameters such as dissolved oxygen, pH
and temperature in this particular study. This is fairly typical in many natural bodies of water.
Note also that conductivity is low at the beginning and end of the study. Other similar
perturbations at the beginning and end may also be evident. In this particular study, the sonde
was not in water when the data collection started, but you can see when it was put in the water
(left side of graph). In fact, you can see in the bottom graph the approximate depth of water at
which the sonde was deployed. Likewise, the data collection continued beyond the point where
the sonde was removed from water (right side of graph). In between, data were collected at 15
minute intervals.
Notice that you now see a new set of menu items in the top line. Some of these functions are
specifically related to viewing and manipulating data. Next we will examine some of the
viewing options.
