| Abstract: | An investigation of ponds, puddles and slow-flowing waters situated in the area of the Polish Antarctic Station distinguished
two groups of diatom communities. The first group characterized waters poor in nutrients and brackish. The number of taxa,
abundance of species and diatom biomass index were all low. Nitzschia homburgiensis, Achnanthes laevis var. quadratarea and A. delicatula prevailed. The second group characterized water richer in nutrients and brackish. The number of species was also low, but
the diatom biomass index was higher. Nitzschia gracilis, Navicula gregaria and Navicula wiesneri formed large populations.
