NH4+-N – ammonium nitrogen; NO3 -N – nitrate nitrogen; P total – Total phosphorus; Ice – the thick of the ice; O2 – oxygen concentrations; Water level – the level of the water; B Cyan.% - the percent Cyanophyta from total biomass; B Flag.% - the percent Euglenophyta and Cryptophyta flagellates from total biomass; Chl – a – chlorophill a concentrations, B total – Total Biomass.
