Answer:
To collect data about a single body of water over time in a table format, you can create a table with the following headings: Date, Time, pH, Temperature, Turbidity, and Dissolved Oxygen.
Under the pH, Temperature, and Turbidity columns, you can cite the means for each of these measures over time. For example, you can calculate the mean pH, temperature, and turbidity for each month or year, depending on how often you are collecting data.
For dissolved oxygen data, you can cite the area of the "dead zone" where dissolved oxygen levels are below 2 mg/L. You can indicate the size of the dead zone and the location where it was observed.
By creating a table with these headings and including the means for pH, temperature, and turbidity, as well as the area of the "dead zone" for dissolved oxygen data, you can track changes in water quality over time and identify trends that may require further analysis.
Hope this helped :)
