...Mary R. Carman; Lloyd D. Keigwin Abstract Abundant Nuttallides umbonifera (Cushman) in Holocene deep sea sediments of the western North Atlantic make them of great value for reconstructing deep sea paleo-environments. This species is particularly abundant in the high-deposition-rate sediments...

... with an outer neritic Midway-type fauna. The fauna indicates meso- to eutrophic conditions in a middle- to outer-neritic setting. The more distal site (OS–28) is characterized by outer-neritic to upper-bathyal taxa (e.g., Cibicides pseudoacutus , Gavelinella beccariiformis , Nuttallides truempyi ) suggesting...

Despite the preservation, the isotopic analysis showed that the low-trochospiral forms were undoubtedly...

... in the deepest-bathyal and abyssal group, because some epibenthic species (e.g., Nuttallides decorata ) are present among the dominants. In the shallower areas, the diversity (species richness) of both calcareous and agglutinated Foraminifera is higher in non-seep than in seep substrates. This distinction too...

In the >150 μm size fraction, Uvigerina mediterranea and Uvigerina peregrina preferentially reproduced and thrived in shallow infaunal microhabitats that are seasonally enriched in phytodetritus. Although the seasonal changes in the 63–150 μm size fraction are less straightforward, Nuttallides...
