Some daily variations may be noticed 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 both ends of the graph. You may notice similar perturbations in some of the other readings as well. In
this example, the sonde was not in the water for a short time at the beginning and end of the study. Not
only can you see exactly when the sonde went in and out of the water, but the bottom graph shows the
depth at which the sonde was deployed.
Notice also 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.
VIEWING DATA
To look at some of the viewing options, click on View (Figure 42). Note that the Toolbar and Status Bar
are turned on (check mark). In addition, the 4-Digit Year expression is checked. Also note that a check
mark is just left of the Graph choice. When a check is next to Graph, all data are expressed graphically in
the opening window.
To show data in both graphical and data table format, highlight the Table menu item, then click or press
Enter. The graphical portion of the window becomes compressed, and the data table becomes visible. If
you then click on View again, both the Graph and Table items have check marks to their left, indicating
that both functions are turned on. You may use your mouse to scroll up/down and left/right to view data.
