Pliocene and Pleistocene chronostratigraphy and paleoenvironment of the central Arctic Ocean
Abstract: Deep-water agglutinated foraminifera (DWAF) were studied from Cores PS2177-5, PS2200-5, PS2212-3 and PS2185-6; from the R/V POLARSTERN ARK-VIII/3 Cruise in the central Arctic Ocean. The sediments were non-calcareous containing a sparse assemblage of eleven DWAF species. A chronostratigraph...

| Summary: | Abstract: Deep-water agglutinated foraminifera (DWAF) were studied from Cores PS2177-5, PS2200-5, PS2212-3 and PS2185-6; from the R/V POLARSTERN ARK-VIII/3 Cruise in the central Arctic Ocean. The sediments were non-calcareous containing a sparse assemblage of eleven DWAF species. A chronostratigraphic framework is presented for Cores PS2200-5 and PS2185-6. Paleoenviron-mental data suggests a bathyal environment (2000-4000m) affected by water masses in the Arctic Ocean. The taxonomy of all of the DWAF found is presented and illustrated. A new species of the Family Trochamminidae; Trochammina lomonosovensis n. sp. is de-scribed and illustrated. INTRODUCTION Location Over the past few years, numerous studies have documented Recent benthic foraminifera from the Arctic Ocean, for exam-ple (Lagoe 1977, 1979). The deep water agglutinated foramini-fera (DWAF) from the central Arctic Ocean have so far |
