“…It should be note that, according to data available from the Murmansk coast (Corner et al, 2001; Marthinussen, 1974; Tolstobrov and Kolka, 2019), the uplift isobases are drawn parallel to the coast. Since the studied lakes are located along the coastline (Figure 1), we can assume that any change in shoreline gradient resulting from possible tilt over time, is negligible and does not require a correction in the reconstructions.…”

Isolation basin stratigraphy and Holocene relative sea-level change on the Barents Sea coast at Teriberka, Kola Peninsula, northwestern Russia

The paper presents isolation basin stratigraphy in bottom sediments from nine lakes in the Teriberka area on the Kola Peninsula, northwestern Russia. Isolation contacts in these basins, identified from lithological and diatom analysis, were used together with 25 radiocarbon dates, to construct a relative sea-level (RSL) curve for the Holocene. Records of marine water re-influx were found in the sediment sequence from one lake, located at c. 17 m a.s.l. The re-influx of marine water seems to be caused by the mid-Holocene (Tapes) transgression and tsunami event. The RSL curve indicates several phases in the postglacial evolution of the Kola coast. An early phase of rapid sea-level fall of c. 32 m around 11,500 cal yr BP, at a rate of c. 40 mm per year, corresponds to glacio-isostatically induced emergence following deglaciation at the Younger Dryas and beginning of the Holocene. In the time interval between c. 11,000 and 7600 cal yr BP, either a stillstand or a slight rise in relative sea level, cresting at about 21 m a.s.l., is suggested in the Teriberka area. This is followed, after c. 7300 cal yr BP to the present day, by a slow glacioisostatic emergence with an average rate of about 2–3 mm per year.
