The physico-chemical characteristics and the planktonic diatom flora were studied in high arctic Loon Lake (Geographical Society Ø, East Greenland). Loon Lake is a cold, monomictic, alkaline, low conductive and likely oligotrophic lake with a maximum water depth of 11.70 m and a low diversity of planktonic diatoms. In summer 2003, the lake-water diatom community consisted of three taxa: frustules belonging to the morphologically highly variable Cyclotella ocellata-polymorpharossii-tripartita-complex were most abundant, and both Discostella pseudostelligera and Fragilaria tenera were of minor importance. The morphological variability of the three diatom taxa is documented by light micrographs.
