 note = {We investigated the morphological features, vertical sinking fluxes, and number densities of the resting cells of ice-associated microorganisms in the 20–100 μm fraction of natural marine sediments collected from ice-covered and ice-free areas around Syowa Station, Lützow-Holm Bay, East Antarctica. We identified the resting cells of various taxonomic groups, including the spores of a diatom, cysts of three dinoflagellates, cysts of five oligotrich ciliates, and the eggs of a mesozooplankton. This is the first report of oligotrich ciliate cysts from Antarctic waters. The resting spores of Thalassiosira australis (diatom), cysts of Polarella glacialis (dinoflagellate), and egg type 1 sink to the bottom sediment during summer. Our results suggest that some planktonic and ice-associated microorganisms in Antarctic coastal areas send their resting cells to the bottom sediments as seed populations for the following generation., 東南極リュツォ・ホルム湾の昭和基地周辺の海氷発達域と開水面域において、海洋沈殿物中の微生物の休眠細胞を調べ、多様な分類群を同定しました。珪藻類の一種の休眠胞子、渦鞭毛藻類二種の卵は夏期間、海底へ沈降していました。この結果は、南極沿岸域に生息するこれらの微生物は、次世代を維持するために休眠細胞を海底へ沈降させていることを示唆します。},
