Fragilariopsis cylindrus (Grunow ex Cleve) Helmcke et Krieger ( Figures 91, 92 View Figures 79–92 , 115, 116 View Figures 113–118 )

Literature: ( Hasle 1965, p. 34, fig. 12:6–12; Snoeijs and Vilbaste 1994, p. 50, fig. 138; Witkowski et al. 2000, p. 360, pl. 213, figs. 8–14).

Description: Length 5–11 µm, width 2–3 µm, striae 15–20 in 10 µm, fibulae 15–20 in 10 µm.

Ecology and distribution: A common bipolar sea-ice diatom, particularly in summer and autumn ( Kang and Fryxell 1992) but also found in brackish-water of the Baltic Sea, forming ribbon-like colonies (Snoeijs and Vilbaste 1994). Fragilariopsis cylindrus has been used as an indicator species for sea-ice movement in both polar regions (von Quillfeldt 2004). It was not observed in Potter Cove during the previous collection. Rare in the material examined.
