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.

Abstract. Summer cyanobacterial blooms represent a threat for the Baltic Sea ecosystem, causing deoxygenation of the bottom water and the spread of the so-called dead zones. The time history of the Baltic Sea cyanobacterial blooms is known from in situ and satellite observations since the early 1980s, but still not well understood. By comparing both weekly-resolved trap sediments 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) are robust semi-quantitative biomarkers for diazotrophic cyanobacteria, and likely mainly 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. Decadal to multi-decadal fluctuations are likely rather related to variability in the Baltic Sea surface temperature and, ultimately, to the Atlantic Multidecadal Oscillation. A 7000 years long 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.

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.

The information space of the Baltic region has gradually developed since the free exchange of cross-border messages was made possible by media technology and international law. The international conflict between Russia and some countries of the European Union has become a factor hampering its sustainable development. Moreover, the conflict has adversely affected the functioning of many civil society institutions in the Baltic Sea region. This study focuses on the publications in the scientific media associated with the political technologies that may provoke conflict but must contribute to good-neighbourly relations in the region. We carry out a comprehensive political analysis and a specific examination of the Western scientific media to develop a package of measures that Russia can take to counter the conflictprovoking influences in the region. The current condition of the regional information space and information operations aimed at inciting Russophobia and forcing Russia out of the European political process is indicative of the politicisation of social sciences and the humanities and of the mythologisation of the policies of the regional social structures. The conflict must be urgently resolved, since the political technologies, which cause instability in the information space, damage the reputations of all the states involved. To reconcile the differences that underlie the information conflict in the Baltic region it is necessary to take into account common interests. There is a pressing need to join efforts in solving the challenging social problems that cannot be overcome without either international cooperation among the countries or effective social partnership.

The political changes of 1989 stimulated a new perception and perspective of the Baltic Sea Region. And this gained momentum with the Eastern Enlargement of the EU. The new situation encouraged research as well. In this context the “Baltic Sea” is not an unchangeable physical setting, but also a construction of different actors or protagonists. People and powers continuously reinvent the Baltic Sea Region. That is why; the following paper focuses on the different notions of the Baltic Sea Region from the Middle Ages up to now and also examines the recent EU-Strategy of this region.

A new “Hanseatic League”, “a global hotspot for health”, “one of the most innovative science macro-regions in the world”? In the fields of life science and technology, politicians and managers of current large research projects describe the Baltic Sea region as a hub of cutting-edge research. How did these images emerge?

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.
