At a temporal and spatial resolution of 3h and approximately 1km the foraminifer flux varied with a factor of 5. The consecutive deployments within the same area, at distances of [approximately equal to]50km differed significantly in flux and relative species abundances. Flux sequences of the total foraminifer assemblage and individual species were significantly autocorrelated. The significance of autocorrelation analyses was affected by sample size of the flux sequences and limited to flux sequences with large fluxes. Autocorrelation in planktic foraminifer fluxes and standing stocks was restricted to distances 〈2km, and were not attributed to the temporal domain.
