Abstract:

Fluxes of silicoflagellates, the dinoflagellate Actiniscus sp., polycystine and phaeodarian radiolarians, tintinnids, ciliate(?) cysts, and pelagic molluscs were estimated for 13 sediment trap samples from the northeastern tropical Atlantic (20°55.3'N, 19°44.5'W) at 2,195 m between 22 March 1988 and 8 March 1989 (site CB1). Each sample integrated the flux over 27 d, and polycystines were identified to species in all samples. Polycystines had the highest fluxes. For phytoplankters, our estimates are lower than most reported data, and for polycystines and tintinnids the values are among the highest ever recorded. Temporal variations in the fluxes of the heterotrophic organisms counted generally were in good agreement with total mass flux, suggesting fairly tight couplings with primary production at the surface. Fluxes of tintinnids were more variable through time and better associated with variations in total mass flux than those of the slower reproducing radiolarians. We identified 145 polycystine taxa. Species compositions changed little throughout the year and did not vary with changes in total mass flux. Comparison of our data with a similar survey of sediment trap samples retrieved between 1 March 1989 and 16 March 1990 from 853 m at the nearby GBN3 site showed significant differences in the fluxes of the groups and in the percentages of many polycystine species. All groups (except silicoflagellates) had higher output rates at CB1, and proportions of several polycystines associated with colder or more productive environments also were higher at CB1. Conversely, GBN3 yielded higher proportions of various radiolarians characteristic of warmer, more oligotrophic waters. Because temperatures below ~70 m are higher at CB1 than at GBN3, different productivity levels, rather than different surface temperatures, may be important in structuring the specific differences recorded.
