Salinity Variations

Salinity and temperature data from the Gulf of Riga, a semi-enclosed sub-basin of the Baltic Sea, were analyzed with a focus on interannual and seasonal variability. The data were compiled from measurements taken from 1973 to 1995, a period which includes the stagnation period in the Baltic Sea. Interannual and seasonal variations in the net inflow of saline water from the Baltic Proper were estimated from volume and salt conservation equations for the period 1973-90. The basic decreasing trend, superimposed interannual variations in salinity, and interannual and seasonal temperature variations in the Gulf of Riga coincided with corresponding changes above the halocline in the Baltic Proper. Seasonal salinity variations were notable in the Gulf of Riga as compared to the Baltic Proper, where variations were negligible. Estimated annual mean inflow varied between 2,000 and 5,000 m3/s (average 3,200 m3/s), with a notable increasing trend. A simultaneous increasing trend was extracted from annual mean river flow data. Short-term fluctuations (over 4-6 years) of annual mean inflow ran opposite to the fluctuations of the magnitude of river flow. The average salinity in the Gulf of Riga increased during strong inflow and weak river flow and decreased when inflow was weak and river flow was strong. Variations in the inflow of water salinity had a minor effect on salinity variations in the Gulf of Riga. Seasonal inflow was strongest in spring and autumn and weak in winter.

Statistical data on reserves, production and exports of Russian oil are provided in the article. The author pays special attention to the expansion of opportunities of sea oil transportation by construction of new oil terminals in the North-West of the country and first of all the largest terminal in Murmansk. In his opinion, one of the main problems in this sphere is prevention of ecological accidents in the process of oil transportation through the Baltic sea ports.

The study of paleogeography of lakes is an actual and important direction in modern science. As part of the study of lakes in the North-West of the Karelian Isthmus, this analysis will establish the dynamics of salinity of objects, which will allow to reconstruct changes in the level of the Baltic Sea in the Holocene.

Palaeoenvironmental Changes

Holocene diatom biostratigraphy of the SW Gulf of Gdańsk, Southern Baltic Sea (part III)The palaeoenvironmental changes of the south-western part of the Gulf of Gdańsk during the last 8,000 years, with reference to the stages of the Baltic Sea, were reconstructed. Diatom analyses of two cores taken from the shallower and deeper parts of the basin enabled the conclusion to be drawn that the microflora studied developed in the three Baltic phases: Mastogloia, Littorina and Post-Littorina. Moreover, the so-called anthropogenic assemblage was observed in subbottom sediments of the study area.

New Syntaxa

The paper characterizes the 3 associations comprising plant communities with Sphagnum rubellum in the south-eastern part of the Baltic region. The new syntaxa differ from each other both in their floristic characters and the pronounced affinity to definite regional mire types and particular habitats. The ass. Drosero-Sphagnetum rubelli is typical of the relatively most thorough ranges. It is observed from the Kaliningrad region to the Karelian Isthmus and, according to the published reference, occurs even throughout the whole area around the Baltic Sea. Its most typical habitat is that of margins of mire lakes and pools. The ass. Eriophoro-Sphagnetum rubelli occurs in central plateaus of convex plateau-like bogs, typical of the areas adjacent to the Baltic Sea coast. It occupies extended flat mire ecotopes with the water level 0.2–0.25 m deep. The ass. Empetro-Sphagnetum rubelli is characteristic of the retrogressive complex in the convex bogs of the East-Baltic Province. It is mostly observed along the coast of the Gulf of Finland. Its stands are rather dynamic and unstable in both space and time. The presence of communities comprised by these 3 associations is an important vegetation character of the series of regional mire types. Assuming an association level of the respective syntaxa seems rational for the purposes of adequate reflection of plant cover diversity.
