Description
Summary:Calcareous foraminifers and hydrographic parameters in 113 bottom samples from the southern Kara Sea were examined to improve the usage of foraminifers as paleoenvironmental proxies for river-dominated high-latitude continental shelves. Foraminif-eral taxa form a succession from near-estuarine to distal open-sea locations, characterized by a gradual increase in salinities. Fora-miniferal assemblages are discriminated into three groups: river-proximal,-intermediate, and-distal. This succession appears to be controlled by a combination of feeding conditions and bottom sa-linities, and are related to riverine fluxes of freshwater, organic matter, and sediments. Morphological and behavioral adaptations of foraminifers to specific environments are discussed.
