Research on cryosestic communities in Svalbard: the snow algae of temporary snowfields in Petuniabukta, Central Svalbard
Although the observations of the colored snow in Svalbard are dated from 17th century, the research in cryosestic algae during last 50 years was focused to NW part of Svalbard, Hornsund and Sveagruva areas. No observations have been reported for the Central or East Svalbard yet, with exception of Lo...
