A Characterization of the Biology and Nutrient Cycling of Two Glacial Lakes in Isfjord Radio, Svalbard
Due to the fact that lakes in the high arctic are only exposed for two to three months out of the year, very little is known about the microbiology and nutrient cycling that occur in this region. Of greatest interest in these high arctic regions are the primary producers that control the majority of...
