Station #4: Water Clarity and Water Color: Go to the Bow (2 photos required)
Secchi Disk and Forel-ule
1.
The secchi disk allows scientists to measure water clarity. The marks on the rope are at 1 meter
increments. Lower the secchi disk into the water until it disappears from view. Record the depth in
meters that the disk dissappeared.
What is the water clarity (in meters)?_______________
2.
The forel-ule scale assigns a number to the color of the ocean. This reflects productivity (the amount of
photosynthesis) in ocean water. Send the secchi disk down two meters. Hold the colored test tubes
over the disk and match a value to the ocean.
What is Forel-ule scale value?___________
3.
In your own words describe the color of the water as it is reflected off the secchi disk.

5.
What can affect water color? Why is the ocean blue one day, greenish another day, and reddish on
some days during spring and summer?
