Abstract	Data on Antarctic coastal sites remain scarce and are generally limited to microscopy; the diversity of coastal Antarctic ecosystems has long been underestimated. The diatom-dominant community in the coastal sea waters of the Fildes Peninsula has been described according to traditional protocols. Molecular diversity of microbial eukaryotes (≤20 µm) from Great Wall Cove and Ardley Cove, Fildes Peninsula, has been determined by Illumina MiSeq2000 sequencing. Inferred metabolisms of summer phytoplankton in the two coves are characterised by autotrophy and heterotrophy. The frequent occurrence of such nanoflagellates as dinoflagellates, Cryptophyta, Stramenopiles, Pyramimonas, Telonema, and Cryothecomonas is predicted to be important in these Antarctic coastal communities. Sea water exchange exists between the two coves when high tide occurs, indicating that there appears to be mixing between the microbial communities in the two coves. Cluster analysis of the microbial eukaryote composition at the phylum and genus levels reveals a conservation of the community composition between the two coves. The inner stations of Great Wall Cove represented by three shoal samples (G1, G2, and G3) are clustered closely together, surrounded by islands and formed into a semi-closed body of water. The samples from the outer stations G4 and G5 of Great Wall Cove, which are separated from the other three Great Wall stations, are more similar to the Ardley Cove samples. Sea water exchange between the outer basins might be the effect of their community compositions. The nanoplankton diversity in Great Wall Cove is richer than in Ardley Cove, according to the α-diversity index.
