RLS Posted May 10, 2007 Report Share Posted May 10, 2007 Is there a secchi disk or clarity reading for Red Lake Ontario? Link to comment Share on other sites More sharing options...
tonyb Posted May 10, 2007 Report Share Posted May 10, 2007 Here you go! Kdx SD = 2.5 (Product of the vertical attenuation coefficient and the depth at which the Secchi disk disappears) EZD : SD = 1.48 (Ratio between depth of 1% light and depth that the Secchi disk disappears) Isu : I = 2.8 (Amount of incident PAR remaining at the Secchi Disk depth, %) Cheers, Tony Link to comment Share on other sites More sharing options...

The above data is confusing to me. :-( The disk readings I am used to are a measurement, usually in feet. Link to comment Share on other sites More sharing options...
Kirk Posted May 11, 2007 Report Share Posted May 11, 2007 ahh memories of limnology 400...I feel like I'm 23 again. I think you'd also need a date as the SD depth would be changing as the water gets warmer Link to comment Share on other sites More sharing options...
