Abstract—The temporary ice algae community in the mixing zone of brackish and fresh waters of the Tagan-
rog Bay of the Azov Sea is described. A high abundance and biomass of planktonic algae and a high chlorophyll
a concentration have been registered in samples of under-ice water taken on February 2013. The mass develop-
ment of the diatom Stephanodiscus hantzschii Grunow blooming on the ice in the eastern part of Taganrog Bay
is described for the first time. The quantitative data on the under-ice microalgae community and the related
hydrochemistry are published. The obtained results could be used in total productivity estimates in the Azov
Sea.
