Atlanta College of Art Limnology Discussion

Answer the questions on the last page of instructions. make sure you have complete answers.

the question below is not complete. Please Find more detail in attached files.

1. Using data on water density as a function of temperature (provided), make a plot of water density for various temperatures. Plot 1) thermally inferred density vs. depth and 2) temperature vs. depth, both at the time of maximum thermal stratification in your dataset.
2. Thermal resistance to mixing is a function of the density difference between the top and bottom of a defined thickness of water. For any column of water with a uniform temperature gradient and dimensions specified, relative units of thermal resistance (‘work’) can be determined from
3. 
   
   Plot
   temperature as a continuous curve vs. depth using your data for the temperate lake under 2
   scenarios: 1) stratified and
   2) post-ice or mixed. Using the curves generated to infer
   temperatures between the actual measurements you made, prepare a table as below
   for each scenario
   

   Depth interval	t2	p2	t1	p1	(p2–p1)
   0-1 cm
   1-3cm
   3-5cm
   Etc.

   In the preceding table, t₁ and t₂ are the temperatures at the top and bottom respectively and p₁ and p₂ are the corresponding densities at temperatures t₁ and t₂. Plot the relative thermal resistance as a function of depth. Note the differences between wind and no wind. What can be inferred about turbulence and vertical currents in the thermocline?
