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.
