Very few comparative taxonomic studies on Arctic and circumboreal diatoms have been conducted in recent years. During the period of Aug. 1996 to 1999 (table 1), we visited a number of island within the Arctic Circle (Baf?n Island, Coburg Island, Beechey Island, Devon Island, Cornwallis Island, Spitsbergen, Greenland) and collected specimens of 20 algal taxa (identi?ed by micrograph observations) of Navicula sensu lato (Chamaepinnularia: 6 taxa, Geissleria: 1 taxon, Luticola: 1 taxon, Navicula: 11 taxa, Placoneis: 1 taxon).
