In recent years, Latvian, Lithuanian, and the Oblast of Kaliningrad coastal zones have been experiencing a particularly intense and rapid anthropisation of the coastline due to political, social, and economic changes at the end of the Soviet period. These pressures are exerting on a highly sensitive environment, which has remained relatively untouched by any major development due to the militarisation of the coasts. The human stakes increased considerably in the coastal zone of the south-eastern Baltic with tourism, industrial development, and urban expansion. The environmental impacts and issues of the post-soviet anthropisation are analysed in this article through a bibliographic compilation related to the evolution of the coastal management policies reconciling environmental protection and economic development.

A detailed study of wind-induced coastal upwelling (CU) in the south-eastern Baltic Sea is presented based on an analysis of multi-mission satellite data. Analysis of moderate resolution imaging spectroradiometer (MODIS) sea surface temperature (SST) maps acquired between April and September of 2000–2015 allowed for the identification of 69 CU events. The Ekman-based upwelling index (UI) was applied to evaluate the effectiveness of the satellite measurements for upwelling detection. It was found that satellite data enable the identification of 87% of UI-based upwelling events during May–August, hence, serving as an effective tool for CU detection in the Baltic Sea under relatively cloud-free summer conditions. It was also shown that upwelling-induced SST drops, and its spatial properties are larger than previously registered. During extreme upwelling events, an SST drop might reach 14 °C, covering a total area of nearly 16,000 km2. The evolution of an upwelling front during such intensive events is accompanied by the generation of transverse filaments extending up to 70 km offshore. An analysis of the satellite optical data shows a clear decline in the chlorophyll-a concentration in the coastal zone and in the shallow Curonian Lagoon, where it drops down by an order of magnitude. It was also shown that a cold upwelling front alters the stratification in the atmospheric boundary layer, leading to a sudden drop of air temperature and near-surface winds.
