Abstract
    The total numbers and biomass of bacterioplankton in two Arctic glacial fjords offwest Spitsbergen were studied. Samples were collected from different water depth layers -from the surface to 80-90 m depth. Total bacterial number (TBN), biomass and morphological structure (shape of bacteria) were determined using the acridine orange direct countmethod. The highest values of TBN and biomass in the water column were found inKongsfjorden in the stations adjacent to Kongsbreen Glacier, and the lowest values in theouter part of the Krossfjorden. The local maxima of bacterioplankton were observed in waterlayers around pycnocline. Themorphological structure was similar in all samples - the bacteria were dominated by rods (over 65%), followed by cocci (16-20%) and vibrios (11-15%).
