Porosira glacialis (Grunow) Jørgensen ( Figures 2–4 View Figures 2–11 , 107, 108 View Figures 107–112 )
Literature: ( Hendey 1964, p. 88, pl. 1, fig. 12; Scott and Thomas 2005, p. 84, fig. 2.41a–f).
Description: Diameter 54–72 µm.
Remarks: Valve areole very fine, either arranged in fascicules or irregularly scattered, sometimes indistinct. Valve surface with scattered spines. A single labiate process located below valve margin and visible in LM.
Ecology and distribution: This is a marine neritic species widely distributed in both the Arctic and Antarctica (bipolar), normally associated with sea-ice flora. It is also known from temperate waters ( Pike et al. 2009). According to Armand et al. (2005), P. glacialis is found on the sediment only as resting spores. In our material, all specimens were vegetative cells that might have been deposited from the plankton. Frequent in Potter Cove.
