Melosira sol (Ehrenberg) Kützing ( Figures 9, 10 )

Literature: ( Hustedt 1930, p. 270, fig. 115 a–d; Scott and Thomas 2005, p. 66, fig. 2.32a–f).

Description: Diameter 62–158 µm.

Remarks: Large specimens of unusual valve size were observed with valve diameter not previously reported. Chains of 3–8 frustules were observed, frustules were connected with narrow bands attached to valves by teethlike projections ( Figure 10 ).

Ecology and distribution: A marine species widely distributed in Antarctica (Scott and Thomas 2005) but does not seem to be of worldwide distribution. Frequent in Potter Cove.
