| Abstract: | The first recorded information about living fresh water diatoms on an ice-wedge furrow is presented. One sample has been analysed and two species, Cymbella aequatis and Tabellaria flocculosa , formed almost half of the diatom population. Some rather rare species for the Canadian Eastern Arctic were identified: Fragilaria constricta, Eunotia lunaris, Eunotia microcephala, Pinnularia gibba, Anomoeoneis zellensis , and Cymbella aspea . Of the 37 species identified, most are common elsewhere in the Arctic. |
