Presence of meiofauna in resuspended sediments was investigated in a tidal creek system employing a specially designed core sampler and quick freezing techniques. Forty core samples were taken during 4 successive ebb tides to determine the distribution of meiofauna in (a) overlying water; (b) resuspended sediment; and (c) undisturbed sediment fractions of each sample. Our experiments demonstrate that 13-44 % of the meiobenthic copepod subcommunity was present in overlying and resuspended sediment fractions, while only a small percentage of nematodes was found simultaneously in these layers. We suggest that selected meiofauna may disperse through tidally coupled mechanisms and that such …
