Revisiting Potter Cove, King George Island, Antarctica, 12 years later: new observations of marine benthic diatoms Author Al-Handal, Adil Y. Author Torstensson, Anders Author Wulff, Angela text Botanica Marina 2022 Warsaw, Poland 2022-02-23 65 2 81 103 http://dx.doi.org/10.1515/bot-2021-0066 journal article 297141 10.1515/bot-2021-0066 163e2ba5-fdc5-4fbf-916e-311eb7062dd4 1437-4323 11000147 Pseudogomphonema kamtchaticum (Grunow) Medlin ( Figures 72, 73 ) Literature: (Al-Handal and Wulff 2008b, p. 430, figs. 95– 100; Medlin and Round 1986 , p. 216, figs. 64–70; Witkowski et al. 2000, p. 343, pl. 60, figs. 13–16). Description: Length 40–65 µm, width 5.5–10 µm, striae 12– 14 in 10 µm. Remarks: Specimens observed in Potter Cove possess less dense striae than reported for this species which normally range between 16 and 23 in 10 µm ( Medlin and Round 1986 ; Scott and Thomas 2005). Specimens smaller than 40 µm were not observed although it might be as small as 18 µm. Ecology and distribution: This is a marine species mostly found as epiphytic and rarely on the sediment, also reported from the Arctic ( Klochkova et al. 2014 ). Frequent in Potter Cove.
