The origin of cyanobacteria in Antarctic sea ice: marine or freshwater?
Summary Cyanobacteria play an important role in the primary productivity of many ecosystems and are dominant in non‐marine polar environments. Apart from detecting low levels of cyanobacteria‐like pigments in the Southern Ocean, little effort has been spent in trying to elucidate Cyanobacteria in An...
