摘要：Microfauna (ostracoda and foraminifera) as component of sediments has been used to detect the dynamics of sea floor condition in NE Kalimantan, particularly off Nunukan and Sebatik Islands. In general, the microfaunal components tend to increase (both number of species and specimens) from near shore to the open sea. The microfauna occur rarely at locations surrounding the islands due to high content of plant remains from the land. The marine origin of microfaunas occurs very abundantly in the inner part of the study area between Tinabasan and Nunukan Islands. This finding is interested due to their occurrence as unusual forms: brownish shells, broken and articulated ostracod carapaces. Additional interested findings are: the incidence of abraded test of Elphidium, the occurrence of dominant species of both ostracoda and foraminifera at some stations; various morphological forms of foraminiferal genus, Asterorotalia that reaches about 1% and distributed in the open sea. The various unusual forms may relate to the dynamics of local environmental changes such as postdepositional accumulation in the sediment, biological activities, and drift currents from open sea to landward.
