Phytoplankton production and chlorophyll content in different types of estuaries
... chlorophyll concentration in estuaries of different types (the Vistula and Curonian Lagoons, and the Volga delta). A comparison with hydrological and chemical parameters helped identify the main factors determining the level of primary production and eutrophication. The productivity of an ecosystem is determined primarily by river runoff in the Volga delta, while in the Vistula Lagoon and Curonian Lagoon by the intensity of water exchange with the
sea. Today, deeutrophication is being observed in ...
Climate Change Impact on the Curonain Lagoon Eutrophication Level
... temperatures in 1990-2000, presumably, a consequence of the climate change, alongside with other factors (freshness, slow water flow) creates conditions for cyanobacterial «hyperblooms». Probably, the 1990-2000 climate warming is the cause of the eutrophication of the Curonian Lagoon, which continues despite significant reduction in external nutrient load.

The problems of the protection of the Baltic Sea in the regions of the Russian Federation: the example of the Kaliningrad region
This article examines solutions to the environmental problems of the Baltic Sea in the Kaliningrad region. The authors focus on the implementation of the HELCOM recommendation, which stipulates the elimination of all sources of eutrophication (the so-called hot spots) as well as the construction of modern waste water treatment facilities. The study is based on the interviews with local experts and the analysis of regulatory documents

The ecological state of the Vistula lagoon using indicators of water quality and eutrophication
The Vistula Lagoon is a transboundary lagoon of the Baltic Sea that is subject to significant pollution and water eutrophication. An assessment of the ecological condition of the lagoon was conducted based on the calculation of modern Russian and foreign water pollution indices for the period 2007—2022. The long-term variability of these parameters was analyzed ...
Construction works impact on the vegetation in the сoastal zone of the Pregolya river in Kaliningrad
... the structure of plant communities and their species composition has changed. Some species have fell out of communities or reduced their projective coverage; some communities in the city center have disappeared. Inherent to the β-mesosaprobic and eutrophic waters, Lemna minor, Cladophora glomerata have increased their abundance in communities, acting as dominants and codominants. The most significant changes in the river vegetation have been identified for two districts. Since 2013, associations ...
Suspended Particulate Matter Distribution Along the Northern Coast of the Kaliningrad Peninsula
The study of suspended particulate matter in the southeastern Baltic Sea is motivated both by human-induced impact and by the natural features of the Baltic Sea, namely, the high levels of eutrophication and complicated sedimentation conditions. The study area is human-occupied, which contributes to the significance of the findings for sustainable nature, and coastal zone, management. The main aim of this research is to study the spatial ...
