These putative flagellate parasites of sea ice diatoms were observed in samples collected in the Bering Sea during March-May 2008, heavy sea ice conditions

Two pennate sea ice diatoms collected at 62.0^oN 171.2^oW; the upper cell is intact, the lower cell is an empty frustule with a dark stained object inside - a dinoflagellate parasite or the cell nucleus?

Unknown protist, possibly a testate amoeba, observed sucking out the contents of centric diatoms in sea ice algae, collected at 57.9^oN 169.2^oW. These protists were farily common in this sample.
