AbstractConventional and chemical munitions dumpsites exist in practically every ocean and a significant number of inland waters. Most of these dumpsites result from post‐World War activities when victorious and defeated states had to dispose of their sizable surplus stocks of munitions, including the difficult-to-handle chemical warfare agents such as mustard, phosgene and nerve agents.The Baltic Sea—with maximum water depths of about 150 m at the dumpsites—seemed to be the easiest way to address the problematic munitions. These activities deposited up to about 300,000 tons of chemical munitions in the Baltic Sea and Skagerrak region, with experts assuming at least another 100,000 tons of conventional munitions in the Baltic Sea alone.Today, these dumpsites are a threat to present and future generations. German authorities addressed some sites because of an immediate threat to the public. This required — based on the sensitivity of the resident and threatened harbour porpoise — a paradigm shift detonation of conventional munitions to an intense investigation of innovative alternatives. The common and innovative alternative solutions considered for the German Baltic Sea coast are presented.

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.

Modern technologies, which provide fast and accurate acquisition of high-resolution spatial data, have found widespread application in the monitoring of coastal processes. This paper reports the results of four years’ monitoring of a huge deflation/blowout/wind-scour basin dynamics at the Vistula Spit (southeast coast of the Baltic Sea). Information about the volume and size dynamics together with deflation/accumulation schemes and 3D elevation maps is presented. Basing on the obtained results, forecast of the deflation basin dynamics for 2016 was proposed. This paper implements the Terrestrial Laserscanning (TLS) method to the coastal processes investigation and demonstrates its high potential in this field.

The study gives quantitative estimation of natural landforms sensitivity of accumulative type coasts exposed to human influence. Foredune is an essential element of a morphological structure of thebarrier spits located at the Baltic Sea sand coasts. The study compares contribution of the beach erosion and deflation (soil drifting) to the foredune degradation on the sea shore of the barrier spit with or without the recreational impact. The analysis is performed for three typical polygons located on the Russian part of the Vistula Spit. Chosen polygons present shore segments with various intensity of tourism: visitors from the village, unregulated camp tourism, and nearly natural conditions. Detailed geodesic survey was carried out on these three polygons (length 515 m, 265 m, and 521 m respectively; total area – 125000 m2) in July of 2015. It was done with single-frequency geodesic GPS Trimble 5700L1 (base station) and TrimbleR3 (rover). Two DEMs were developed using the results of laser scanning of 2007 and the survey of 2015. Volume deformation for whole polygons and its particular parts (beach and foredune ridge) was made by comparison of the DEMs. In the case of touristic load the effect of deflation is 5-15 times higher than the marine erosion of foredune edge. If not affected by an anthropogenic factor the foredune erosion is caused mainly by the sea, and its impact is 6 times higher than that of the natural deflation.
