Sample of the 5th of June 2014

Hi, I will usually put in the FB page the pictures and on this blog I will describe the sample.
Yesterday I took the first sample in Lake of Lugano, I got samples of water in bottles from the depth of  0m, 5m, 10m, 15m, 20m, 25m and 30m.
When I was on the surface I analyzed all this samples and you can see the results.

Regarding the visibility (Secchi disk) this are the horizontal values

and for the vertical value, from the surface, the visibility was 3.70 mt!
