Vertical distribution of bacteria in arctic sea ice
Heterotrophic bacteria were enumerated in north polar sea ice cores obtained near Point Barrow, Alaska. Highest concentrations of total and viable bacteria were found in the layer containing the sea ice microbial community identified by the maximum chlorophyll a content. Gas vacuolate bacteria were...

Heterotrophic bacteria were enumerated in north polar sea ice cores obtained near Point Barrow, Alaska.
