Stable isotopes 18O and 13C record of the Kapp Starostin Formation (Late Permian) is presented. The interdependence of δ18O nad δ13C isotope time series is applied for calculating paleotemperatures in the depositional basin of the Kapp Starostin Formation. The obtained results indicate overall cooling from c. 25°—10°C, and confirm some paleogeographical and paleoclimatical inferrences.
The paper describes the communities of laminarians and their macrofauna at the western coasts of Spitsbergen. The following aspects are considered: specific composition of fauna, spatial distribution of animals within the algae, trophic structure of fauna associated with the laminarians. Some zoogeographic remarks are included.
The infauna of the soft bottom of Nottinghambukta was studied quantitatively. The distribution of 5 most abundant species: Liocyma fluctuosa (Bivalvia), Dendrodoa grossularia (Ascidiacea), Priapulus caudatus and Halicryptus spinulosus (Priapulida) and Chone duneri (Polychaeta), in this Arctic estuary has been presented.
