The sandy coasts of the south–eastern Baltic Sea are the unique landscape along the shores of Poland, Kaliningrad Oblast (Russia), Lithuania and Latvia. Flat sandy beaches, protective dune ridges and near shore sandy spits are very valuable and attractive resources for human recreation and valuable habitat for wildlife. Intensifying shipping, operation of oil terminals and offshore platforms poses a constant threat not only to coastal and socio–economic resources, but also to sensitive underwater landscapes of marine areas and vulnerable marine habitats. Analysis of environmental sensitivity proved to be an effective tool for national and regional oil spill response planning. However, in order to complete the precise evaluation of near shore and coastal zone sensitivity to possible oil spills there is a need to identify vulnerable coastal sectors and complete detailed mapping of underwater landscapes. This is achieved by developing an integrated methodology for analysis of valuable coastal zone sensitivity to potential oil spills.

The state-of-art in oil spill modelling methods is summarized, focusing on development since 2000. Some recommendations for possible application of these methods to the south–eastern part of the Baltic Sea are prepared. Particular attention is paid on the methods of parameterization of volume of oil spill and calculation of advection of the oil spills. Consideration is also given to methods used in oil weathering models.

The Baltic Sea is facing exceptionally intensive marine traffic. Oil products in addition to other cargo types are being transported in this marine area. Therefore, the risk of potential oil pollution is very high. Although, the Baltic Sea has not experienced catastrophic oil spills, there have been spills causing serious environmental damage in the region. Construction of oil terminals and planned growth of Russian oil export through Baltic Sea ports along with the operation of large oil enterprises and oil drilling platforms make maritime safety a priority task for the Baltic Sea region. The publications collected in present Baltica Journal Special Issue set sights on the improvement of oil spill management in the South–Eastern Baltic Sea as well as stimulate the appearance of new transnational response agreements in the region.

The annual average features of the spatial distribution of oil pollution at the sea surface in the south–eastern part of the Baltic Sea were determined for the first time. It was shown that the most polluted areas are the seawaters west of the Sambian Peninsula and Vistula Spit, including the coastal zone that is connected to the Baltiysk, Gdansk, and Gdynia ports. The sea surface near the oilfield Kravtsovskoye D-6 (Russia) and oil terminal Būtingė (Lithuania), as well as the coastal zone near the Curonian Spit, do not suffer from oil pollution. A lower estimation of the annual average amount of oil products at the sea surface was performed. The lack of correlation between the location of the oil slicks and main navigation routes by Automatic Identification System (AIS) was explained by the infrequent but large spillages from ships that occur outside of the main traffic lanes. A significant contribution to the oil pollution of the sea surface from nonconventional ships not equipped with AIS was discovered.

Abstract The applicability of a numerical model following a downscaling methodology was evaluated for the south-eastern Brazilian shelf (regional model) and Paranaguá estuarine system (local model). This approach permits the simulation of different scale processes, such as storm surges and coastal upwelling, and is suitable for operational forecasting purposes. When large areas are covered by regional models, the tidal propagation inside the domain can be significantly affected by the local tidal potential, mainly where the resonance phenomenon is observed. The south-eastern Brazilian shelf is known for the resonance of the third-diurnal principal lunar tidal constituent (M3), the largest amplitudes being found in the Paranaguá estuarine system. Therefore, the significance of the local tidal potential was assessed in this study for the most important tidal constituents inside the estuarine system (including M3). The model validation was performed with tidal gauge data, Argo float profiles and satellite measurements of Sea Surface Temperature. The methodology described in this study can be replicated for other important estuarine systems located on the south-eastern Brazilian shelf. Furthermore, the numerical model was developed within a perspective of operational nowcast/forecast simulations, useful for several activities such as navigation and response to emergencies (e.g., oil spills).

The article focuses on some peculiarities of the Ingrian Finnish dialect spoken in the former Lutheran parish of Liissilä in Central Ingria.Two main pecularities of the Liissilä dialect are the imperative 2Sg -kai and a special group of verb type with the -oi stem ending. Most of the isoglosses, which were previously proposed as typical of the Äyrämöinen dialect, are currently absent in the Liissilä dialect. The dialect of Liissilä partially preserves two old pecularities of the Äyrämöinen dialect, namely nouns ending in - ее and verbs ending in - oi. On the other hand, there are quite a lot of areal isoglosses, which are common in local dialects of both Savakko (Inkere, Venjoki) and Äyrämöinen (Liissilä, Tuutari) parishes. These isoglosses include tarttu ‘potato’, potra ‘beautiful’, hirvitä ‘to be afraid’, the presence of the diphthong in the 3Sg imperfect form, the 1Pl affix -mma , the vowel ö in the verb pölästyy ‘to be scared’, the present stem niäe- of the verb nähhä ‘to see’ and some others. In the Linguistic Atlas of the Baltic-Finnish Languages the dialect zones of the Finnish language, including such units as the “South-Eastern Southern dialect” or the “dialect of Northern Khyame” are classified as “Evremeysky dialect”, “Savaksky dialect” and “dialect of Narvusi” in the territory of Ingria.

The present study area is located within the south–eastern segment of the Baltic Sea framed by 55o30’–56o30’ N and 19o00’–21o15’E. The area is re-visited with the aim to describe in more detail the geologic prerequisite and development of the palaeo–incisions as well as the timing of their subsequent infillings. The channels form distinctive features in the sedimentary bedrock along the outer limits of pre–Weichselian ice sheets, on average reaching depths into the bedrock of 50 m in the nearshore zone of Lithuania to 100 m along the slope to the Gotland depression in the west. The development of palaeo–incisions systems is governed by the easily eroded late Palaeozoic to Mesozoic bedrock of the present area. Only rare ocurrences of channels have been reported from the middle and lower parts of the Palaeozoic further west in the Baltic Sea. The present investigation supports a mechanism that the channels formed below the ice near the ice sheet margin by melt water erosion under high pressure. The channels start at random where a fracture in the ice develops forming outlet of water contained below the central part of the ice sheet. The channels often merge together in the direction of the ice margin, possibly gradually adapting to previous fracture systems in the bedrock. The investigated incisions were infilled prior to the advance of the Weichselian ice sheet and some have been reopened and repeatedly infilled.

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.
