CRYOPELAGIC FLORA O F THE CHUKCHI, EAST SIBERIAN AND LAPTEV SEAS
Abstract: In the lower layer of young and first-year drifting and fast ice at 125 stations were found more than 120 algal species, the pennate diatoms primarily from the genera Navicula (24 species) and Nitzschia (20) predominating. The list of species is given. At many stations the ice bloom was ob...

| Summary: | Abstract: In the lower layer of young and first-year drifting and fast ice at 125 stations were found more than 120 algal species, the pennate diatoms primarily from the genera Navicula (24 species) and Nitzschia (20) predominating. The list of species is given. At many stations the ice bloom was observed in 0.2-0.5 cm of the lower layer. Freshwater diatoms and the majority of marine planktonic Chaetoceros and Thalassiosira species represent the allochthonous element of ice flora. Twenty-five dominant species were revealed, the following being frequent: Nitzschia frigida, N. cylindrus, N. sp. cf. prornare, N. grunowii, N. delicatissima, N. polaris, Navicula pelagica and N. septentrionalis. |
