<p>The BSUIN (Baltic Sea Underground Innovation Network) aims to enhance the accessibility of the underground laboratories in the Baltic Sea region for innovation, business and science. One of the BSUIN project activities is characterization of natural background radiation (NBR) in underground facilities. In this talk results from NBR measurements performed in Callio Lab, Pyhäsalmi, Finland, at the depth of 4100 m w.e. will be presented. The in-situ gamma spectra were collected with the use of  HPGe semiconductor spectrometer, whereas the  concentration of radon were measured with RAD7 electronic detector. In addition, the water and rock samples were taken for laboratory analysis in Institute of Physics, University of Silesia, Poland. The concentration radioisotopes in water samples were performed by using a liquid scintillation α/β counter (LSC) and α-particle spectrometry, while the concentration of radioisotopes in rock samples were performed by using laboratory gamma ray spectrometry and also α-particle spectrometry.</p>

<p>The Reiche Zeche mine is one, out of 6 Underground Laboratories (ULs) participating in the BSUIN (Baltic Sea Underground Innovation Network) project. The main goal of BSUIN is to improve the utilisation of Underground laboratories operating in the Baltic Sea Region by creating an umbrella organisation, an association, to represent the underground locations. To improve the utilisation the Uls, the sites have been characterized to understand the possibilities of the sites. Of of the studied characteristics is natural background radiation. The Reiche Zeche mine is located at a depth of 150 m (410 m w.e.) in the eastern part of the Erzgebirge Mountains, Germany. The measurements of natural background radiation (NBR) were performed: (1) in-situ by using portable HPGe semiconductor spectrometer and RAD7 electronic radon detector, and (2) in the laboratory, where the concentration of radioisotopes in water and rock samples was determined. The laboratory measurements were done in the Institute of Physics, University of Silesia (Poland) by using a liquid scintillation α/β counter (LSC), gamma-ray spectrometry and α-particle spectrometry. The obtained results of natural radioactivity in Reiche Zeche (BSUIN UL) will be presented.</p>

Abstract. Summer cyanobacterial blooms represent a threat to the Baltic Sea ecosystem, causing deoxygenation of the bottom water and the spread of the so-called dead zones. The history of the Baltic Sea cyanobacterial blooms is known from in situ and satellite observations since the early 1980s but is still not well understood. By comparing both weekly resolved sediment trap material and a well-dated sediment core from the eastern Gotland Basin with monitoring and satellite cyanobacterial data of the last ca. 35 years, it is shown here that 6- and 7-methylheptadecane lipids (expressed as 6+7Me-C17 : 0) may be potentially considered semiquantitative biomarkers for diazotrophic cyanobacteria, and more specifically for Nodularia spumigena. Using this organic proxy, it was thus possible to reconstruct the history of cyanobacterial blooms beyond the observational period with a resolution of 2–4 years since 1860. Cyanobacteria were constantly present but in relatively low abundance until 1920, when they started to alternate between periods with high and low abundance. Interestingly, there seems to be no significant increase in cyanobacterial abundance in the 1950s, when eutrophication and deoxygenation of the Baltic Sea increased considerably. While the early increase in cyanobacteria may be related to a small increase in phosphorus loading, decadal to multi-decadal fluctuations are likely related to variability in the Baltic Sea surface temperature and, ultimately, to the Atlantic Multi-decadal Oscillation. A 7000-year 6+7Me-C17 : 0 record from the Bothnian Sea also suggests a relationship with the mean summer temperature in the Baltic Sea region but at a multi-centennial to multi-millennial timescale. The intensity of the cyanobacterial blooms in the Baltic Sea is thus likely mainly related to natural processes such as temperature variability, at least at a multi-decadal to multi-millennial timescale.

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.

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.

Health And Well Being

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.
