The article contains materials on the study of landslide deposits in the upper reaches of the Mzymta river basin. The results of14C analysis showed that the youngest landslides are common on the southern slope of the Psekhako Ridge and date back to less than 200 and 390±90, 400±70 years ago BP and more than 770±150 years BP. The most ancient landslide-collapse on the northern slope of the Aibga Ridge and dates back to 1110±90 years BP.

Zoya Ilyinichna Glezer is the largest Russian micropaleontologist, a specialist in siliceous microfossils — Cenozoic diatoms and silicoflagellates. Since the 1960s, she systematically studied Paleogene siliceous microfossils from various regions of the country and therefore was an indispensable participant in the development of unified stratigraphic schemes for Paleogene siliceous plankton of various regions of the USSR. She made a great contribution to the creation of the newest Paleogene schemes in the south of European Russia and Western Siberia, to the correlations of the Paleogene deposits of the Kara Sea.

Excavation at a crop-mark site found close to Annan, Dumfries and Galloway, revealed evidence of a ring-ditch containing a number of intriguing internal structures. Initially this was presumed to be a prehistoric monument, but pottery and radiocarbon dating, unexpectedly, indicated that the main structural phase of the site falls between the 11th-13th centuries AD. This suggests that a degree of caution is required when interpreting crop-mark sites on morphological characteristics alone. Moreover this excavation makes clear that morphological interpretation can have a constraining influence on excavation strategy, so caution is required when designing fieldwork programmes.

We studied in detail a moss-lichen component of Shokalsky Island vegetation for the first time and identified 79 species of mosses and 54 species and 2 subspecies of lichens and lichenicolous fungi. All species of mosses and 23 species and 2 subspecies of lichens and lichenicolous fungi are recorded for the first time for the island. The study is based on collections made in South West part of the island, in arctic tundra. We also explored the participation of the mosses and lichens in the main types of plant communities and the species distribution in 10 ecotopes. The paper describes the noteworthy findings (Abrothallus parmeliarum, Aongstroemia longipes, Arthonia peltigerea, Caloplaca caesiorufella, Catillaria stereocaulorum, Ceratodon heterophyllus, Lecanora leptacinella, Sphagnum concinnum, S. olafii) and features of bryo- and lichenoflora of Shokalsky Island.

International experience of oil spill response in the sea defines the priority of coastal protection and the need to identify as most valuable in ecological terms and the most vulnerable areas. Methodological approaches to the assessing the vulnerability of Arctic coasts to oil spills based on international systems of Environmental Sensitivity Index (ESI) and geomorphological zoning are considered in the article. The comprehensive environmental and geomorphological approach allowed us to form the morphodynamic basis for the classification of seacoasts and try to adapt the international system of indexes to the shores of the Kara Sea taking into account the specific natural conditions. This work has improved the expert assessments of the vulnerability and resilience of the seacoasts.
