Kirje Lake Peipsi 2019 (Phytoplankton samples)(2019) Blank, Kätlin (Leg.); Tuvikene, Arvo (Leg.); Palmik-Das, Kadi (Leg.); Tuvikene, Lea (Leg.); Maileht, Kairi (Det.); Eesti Maaülikool. Loodusteaduslikud kogudMethod: Phytoplankton samples were preserved in Lugol’s (acidified iodine) solution and counted under an inverted microscope (Utermöhl, 1958). 3-10 ml of preserved sample was settled overnight and counted in random fields or transects. Biovolumes of algal cells, colonies and/or filaments were calculated using assigned geometric shapes dimensions, and converted to biomass assuming the specific density of 1 g cm-3 in accordance with Edler (1979). Approved by CEN on 14 July 2006 “Water quality - Guidance standard on the enumeration of phytoplankton using inverted microscopy (Utermöhl technique)” (CEN 15204, 2006) European Standard EN 15204:2006 Utermöhl, H., 1958.
