AbstractThe increased demand for wood to replace oil-based products with renewable products has lifted focus to the Baltic Sea region where the environment is favorable for woody biomass growth. The aim of this study was to estimate broad-sense heritabilities and genotype-by-environment (G×E) interactions in growth and phenology traits in six climatically different regions in Sweden and the Baltics. We tested the hypothesis that both bud burst and bud set have a significant effect on the early growth of selected poplar clones in Northern Europe. Provenance hybrids of Populus trichocarpa adapted to the Northern European climate were compared to reference clones with adaptation to the Central European climate. The volume index of stemwood was under low to medium genetic control with heritabilities from 0.22 to 0.75. Heritabilities for phenology traits varied between 0.31 and 0.91. Locally chosen elite clones were identified. G×E interactions were analyzed using pairwise comparisons of the trials. Three different breeding zones for poplars between the latitudes of 55° N and 60° N in the Baltic Sea Region were outlined. The studied provenance hybrids with origin from North America offer a great possibility to broaden the area with commercial poplar plantations in Northern Europe and further improve the collection of commercial clones to match local climates. We conclude that phenology is an important selection criterion after growth.

<p>Estonia is located in the norther part of the Baltic Sea region characterized by land uplift and prograding coasts. On uplifting sedimentary coasts, a variety of coastal landforms can be found. Sometimes the partly buried or elevated coastal formations appear as extensive stripe-like patterns populating coastal plains up to 5–10 km inland. These ridge systems are mostly called beach ridge plains, strandplains and foredune plains. The ridge systems are offering a unique opportunity to examine the events over at least the last 7,000 years when the Baltic Sea mean water table has been consistently dropping and a steady shoreline advancement has been punctuated by rare extreme events. We have found that the signs of past storms are clearly reflected in the internal structure and size of the ancient ridges. It can be assumed that high ridge systems containing extensive seaward-dipping layers formed 3,500–3,000 years ago are reflecting period of extreme storms and high influence of maritime climate, while the following small, nearly unnoticeable ridges, formed 3,000-2,200 years ago are reflecting calm period, probably with more continental climate. The current study is focusing on this shift in climatic conditions and is trying to find shifts in different ecosystems during the same period.</p><p>In this study, GIS analyses based on LiDAR topography were carried out in the coastal ridge systems. Number of study areas with different exposure to the storms and different rates of land uplift were selected. Ridge system patterns from the age of 3500-2200 BP were analysed. The ages for this study were acquired from published luminescence and radiocarbon dating results. Additionally, land uplift rates were used to determine approximate age of the formations. These results were compared with other studies based on the literature analyses. These analyses included: ground penetrating radar studies; records of aeolian sand influx into the coastal peat bogs in Estonia and in Northern Europe; past climatic records of northern Europe; and number of studies related to other ecosystems.</p><p>We have found that during the period of increased storminess and more maritime climate, 3500-3000 years ago, an increased sand influx was reported into the coastal peatbogs. Moreover, number of ground penetrated radar studies along Estonian coast have detected several extensive erosional layers in the internal structure of coastal landforms. In contrast, during the following period, such markers are completely missing. Additionally, notable change has been found in wetland ecosystems where we can find rapid shift from fen phase to raised bog phase around 3000 years ago. All these results are indicating that, for some reason, the climate in our region changed rapidly from western cyclones dominated maritime climate to much calmer and dryer continental climate.</p><p>What where the reasons behind this climatic shift, how it might have influenced different ecosystems, how likely it might happen again as a result of global warming and how we need to take it into account in coastal management plans will be also discussed in this poster.</p>

AbstractGeological investigations of a part of the crystalline basement in the Baltic Sea have been performed on a drill core collected from the depth of 1092–1093 m beneath the Phanerozoic sedimentary cover offshore the Latvian/Lithuanian border. The sample was analyzed for geochemistry and dated with the SIMS U–Pb zircon method. Inherited zircon cores from this migmatized granodioritic orthogneiss have an age of 1854 ± 15 Ma. Its chemical composition and age are correlated with the oldest generation of granitoids of the Transscandinavian Igneous Belt (TIB), which occur along the southwestern margin of the Svecofennian Domain in the Fennoscandian Shield and beneath the Phanerozoic sedimentary cover on southern Gotland and in northwestern Lithuania. It is suggested that the southwestern border of the Svecofennian Domain is located at a short distance to the SW of the investigated drill site. The majority of the zircon population shows that migmatization occurred at 1812 ± 5 Ma, with possible evidence of disturbance during the Sveconorwegian orogeny.

Abstract In the future, health promotion would require developed strategies that lead to stronger cross-sectoral cooperation. Cross-sectoral cooperation enables the integration of fragmented resources and competencies, which benefit service solutions for urban health. Healthy Boost “Urban Labs for Better Health for All in the Baltic Sea Region”, funded by the EU Interreg Baltic Sea Region -program, aims to develop the Model for cross-sectoral cooperation, which will be tested in the cities of the Baltic Sea Region during 2020-21. The self-assessment tool for cross-sectoral cooperation was developed, and the self-assessment among the nine cities in seven countries from the Baltic Sea Region was conducted in 2019. The results indicated to what extent the staff (n = 329) in the cities have recognized the cross-sectoral cooperation for health and wellbeing as strategically crucial in their policies, communication, and in the design of their organizational functions. The daily practices were evaluated in terms of how systematically cities have implemented cross-sector actions for health and wellbeing. The biggest challenges for cooperating across sectors for the cities were coordination and systematic identification of the community needs for health promotion. The cooperative actions were less systematic than expected in the strategic approach. The variation among respondents' assessments was high within the cities that lead to a conclusion about existing gaps in coordination, communication, and leadership of cross-sectoral work within the cities. The Likert type self-assessment measurement was statistically reliable in both strategic and operational dimensions of cooperation. Key messages Evaluation and measurements are needed to identify cross-sectoral actions to health and well-being. The evidence-based Model developed in the Healthy Boost project will guide partners towards systematic cross-sectoral cooperation processes.

Exhaust Gas Emissions

AbstractTo assess the value of the environmental benefits of the Sulphur Emission regulation (SECA) that came into force in 2015, changes in depositions of SOx and NOx from ship exhaust gas emissions were modelled and monetized for the Baltic Sea region for the years 2014 and 2016. During this period, the total deposition of SOx in the study area decreased by 7.3%. The decrease in ship-originated SOx deposition from 38 kt to 3.4 kt (by over 88%) was translated into a monetary value for the ecosystem impacts of nearly 130 million USD, according to the EcoValue08 model. This is less than the modelled health benefits, but it is not insignificant. For NOx, there was no decreasing trend. The exceedance of the critical loads of SOx and NOx was also estimated. The effect of Baltic shipping on the exceedance of critical loads of acidification after SECA is very small, but Baltic shipping still has a considerable effect on the exceedance of critical loads for eutrophication.

Since prehistoric times, the Baltic Sea has functioned as a northern mare nostrum — a crucial nexus that has shaped the languages, folklore, religions, literature, technology, and identities of the Germanic, Finnic, Sámi, Baltic, and Slavic peoples. This anthology explores the networks among those peoples. The contributions to Contacts and Networks in the Baltic Sea Region: Austmarr as a Northern mare nostrum, ca. 500-1500 ad address different aspects of cultural contacts around and across the Baltic from the perspectives of history, archaeology, linguistics, literary studies, religious studies, and folklore. The introduction offers a general overview of crosscultural contacts in the Baltic Sea region as a framework for contextualizing the volume’s twelve chapters, organized in four sections. The first section concerns geographical conceptions as revealed in Old Norse and in classical texts through place names, terms of direction, and geographical descriptions. The second section discusses the movement of cultural goods and persons in connection with elite mobility, the slave trade, and rune-carving practice. The third section turns to the history of language contacts and influences, using examples of Finnic names in runic inscriptions and Low German loanwords in Finnish. The final section analyzes intercultural connections related to mythology and religion spanning Baltic, Finnic, Germanic, and Sámi cultures. Together these diverse articles present a dynamic picture of this distinctive part of the world.
