In 2013 a team of marine scientists established the global citizen science Secchi disk programme for seafarers to study the marine phytoplankton.

Water clarity was moderately good throughout the lake, and the secchi disk results indicate the lake is mesotrophic, or moderately enriched.

The average Secchi disk transparency from 2000-2005 ranged from 9.0 11.5 feet ( CLMP data ).

During this period, five years of basic chemical information was collected, in addition to 8 years of Secchi Disk Transparencies ( SDT ).

I think he meant that in the absence of suspended inorganic particulates, the Secchi disk will measure the amount of algae in the water, basically.

The Secchi disk has the advantages of integrating turbidity over depth ( where variable turbidity layers are present ), being quick and easy to use, and inexpensive.
17.
The turbidity tube condenses water in a graded tube which allows determination of turbidity based on a contrast disk in its bottom, being analogous to the Secchi disk.

From this data, the median total phosphorus ( TP ) concentration in 2008 was 7.5 parts per billion ( ppb ) and mean secchi disk transparency was.

From this data, the median total phosphorus ( TP ) concentration in 2008 was 6.5 parts per billion ( ppb ) and mean secchi disk transparency was.

The reflectance percentage can be correlated to attenuation, Secchi disk depth or total suspended solids although the exact relationship will vary regionally and depends on the optical properties of the water.
