Testing the visibility
(turbidity)
We lowered the disk until we couldn't see it,
counting the stripes on the rope every meter. |
Checking the oxygen
content of the water
We used a digital electronic oxygen probe to
check the oxygen content in milligrams per liter
and percent saturation. |

Pouring a water sample
from 20 meters below surface into the testing

Reading the salinity
of the water in parts per millon using a
refractometer
The
refractometer works on the principle that higher
salinity bends light waves more. |
