,WONIAK'S CLASSIFICATION OF NATURAL WATERS
Sources:The only parameter describing light attenuation coefficients Kd (total), and Kpl (by phytoplankton pigments) is chlorophyll a concentration Ca. The equations of classification are as follow:
,
where:
for Southern Baltic waters,
D
K(l)=0
for case 1 waters.
The parameters are given in table below.
lambda - [nm]; a1, a2 - [m3*mg-1]; A1, A2, Kd,j, Kc,j - [m-1*(mg*m-3)-1]; Kw - [m-1]
