Preface & acknowledgements The Baltic Sea in the Northeast of Europe is a semi-enclosed body of water with unique marine, littoral and terrestrial ecosystems. Unlike other coastal regions in Europe, such as the North Sea and the Mediterranean, the coasts of the Baltic Sea are less strongly modified by man and its multiple uses of the coastal zone. This is partly due to the fact that the Baltic Sea hinterland is less densely populated than other European regions. Another kind of “coastal conservation” came by a “whim of history” to the Southern and Eastern parts of the Baltic. Political ideologies and decisions were responsible that the Baltic coast from Lübeck in Germany to St. Petersburg in Russia served as “iron curtain” border between the eastern European countries under Soviet influence and the remainder of Europe for 45 years. Irrespective of the fact that this border situation was unfortunate and sad from a human perspective, the coastal environment and landscape received noticeable benefits from this situation. Sealing off most of the coastal strip from intensive residential, industrial and recreational uses gave room to nature and wildlife. Thus, valuable coastal ecosystems and habitats could develop here over decades. After the regime changes in the early 1990s the line of the Iron Curtain was transformed into a Green Belt, a nature conservation zone, through Europe from the Barents to the Black Sea. Until recently this European Green Belt had a significant gap – the stretch along the Baltic Coast. Thus, it seemed obvious that this gap ought to be closed and a Baltic Green Belt needed to be established and linked to the neighbouring Belts so as to create a Pan-European Green Belt system. The idea for a Baltic Green Belt project was proposed in 2008 and was welcomed by the EU INTERREG community for the Baltic Sea Region. As more than 15 years had passed after the political turnover, the changes along this coastal zone were in full progress and the human pressures on the coastal landscape and seascape were building up. At an increasing speed tourism and recreational activities are conquering the coast with its wonderful natural features such as pristine forest, impressive dune systems, soft and hard rock cliffs and many others. Moreover, agriculture, urbanization, harbour and marina developments are spreading out towards and along the waterfront. Therefore, it seemed wise to initiate a dialogue and concerted actions among and between the key stakeholders in all iron curtain countries, i.e. Germany, Poland, Lithuania, Latvia and Estonia. The stakeholders defined the following goals as primary objectives of the Baltic Green Belt project: development of an ecological network under the umbrella of the European Green Belt following the Green Belt vision collaboration of environmental NGOs, universities and authorities for a sustainable development of the coast protection of the environment and natural resources; improvement of the ecological status of the marine and terrestrial Baltic Sea area (eutrophication, waste water, agriculture, tourism) supporting the implementation of the HELCOM Baltic Sea action plan for the protection of the Baltic evaluation of the implementation of international agreements for coastal nature protection along the Baltic Green Belt identification of barriers and success factors/indicators of sustainable coastal development contribution to the EU Strategy for the Baltic Sea by preserving natural zones and biodiversity. The stakeholder community of the project is comprised of NGOs, scientific institutions, public authorities and economic stakeholders and thus excellently mirrors the Green Belt tradition of successfully integrating a wide set of actors and supporters. Although, for political reasons, Russia could not serve as an official partner in projects funded by EU INTERREG at the starting point of the project, joint efforts of the partner community succeeded in incorporating Russian NGOs and institutions as associated partners who actively participated in the project work. For the purpose of project guidance a Steering Committee was established in order to provide both scientific and practical advice for the project work. At this point, in April 2012, after numerous meetings, conferences and workshops the Baltic Green Belt project has finished its designated work. The results of this work are summarized in this volume. Across many borders, similar problems have been found and problem solutions have been discussed and often identified. As a whole our work has demonstrated (once again) that sustainable coastal development is to be reached only by transnational and concerted multi-stakeholder efforts. Everyone involved in the project has also realized that there is no alternative to sustainable development for this coast, if remaining treasures of nature ought to be preserved. It’s up to the individual reader now to decide which and how many of the results and insights presented here are relevant to him or her. For the lead partner of the project it is clear that the benefits of the project cooperation are enormous and go far beyond the results published here. Personal friendships, mutual visits, intensive communication pathways and collegial partnerships were established along the progress of the BGB project. Many of these will continue a long time beyond the project phase. Therefore, we want to thank the EU INTERREG BSR Programme for financing the project work as well as the State government of Schleswig-Holstein for additional support to keep the Russian partners involved. Most of all, however, we express our gratitude to all partners and persons who have been engaged in the Baltic Green Belt idea and project in one way or another. It has been a great pleasure to work in this team!

Coastline Reports 20 (2012), ISSN 0928-2734, ISBN 978-3-939206-05-7 S. 77 - 87 Involving Stakeholders along the Baltic Green Belt of Latvia Erik Sachtleber1 & Andra Ratkeviča2 1Institute of Geography, Kiel University 2Dabas aizsardzības pārvalde, Latvia Abstract An essential part of nature protection is involving stakeholders by communicating the need and the benefits from conserving nature. This is very often not easy to handle, the communication with important stakeholders can be disrupted and communication with these stakeholders might malfunction. In these cases a neutral mediator can influence the process and atmosphere of communication in a way that most disruptions and barriers can be overcome. The Slitere National Park is taken as an example for the processes of communication in nature protection and the impact of a neutral stakeholder in a complicated communication regime. This paper analyses the process of communication, which circumstances influenced this process, the history of the area and its stakeholders. As a result, general guidelines for strategic communication with stakeholders in nature protection are given. 1 Introduction An important part of nature conservation is to reduce the pressure of mankind on nature, for example by reducing the negative effects of stakeholders (organisations or key persons with an interest in the usage of land in a nature protection site), economic development and people’s lifestyle. This means, nature protection depends on involving stakeholders; forming alliances and agreements with those who might harm nature with their actions, although it is not their aim – for example in tourism.

Stratification of the water column was mainly Thermocline; controlled by the temperature while salinity had only a minor contribution. Buoyant salinity maxima with variable strength were observed in the intermediate layer of the Gulf of Riga. The Gulf of Riga; salinity maxima were likely formed by a simultaneous upwelling—downwelling event at the two Water exchange; Intrusion opposite sides of the Irbe strait. The inflowing salty water did not reach the deeper (> 35 m) parts of the gulf and, therefore, the near-bottom layer of the gulf remained isolated throughout the summer. Thus, the lateral water exchange regime in the near bottom layer of the Gulf of Riga is more complicated than it was thought previously. We suggest that the occurrence of this type of water exchange resulting in a buoyant inflow and lack of lateral transport into the near-bottom layers might contribute to the rapid seasonal oxygen decline in the Gulf of Riga. # 2016 Institute of Oceanology of the Polish Academy of Sciences.

Seasonal variability of radiation tide in Gulf of Riga Vilnis Frishfelds1, Juris Sennikovs1, Uldis Bethers1, and Andrejs Timuhins1 1Faculty of Physics, Mathematics and Optometry, University of Latvia, Riga, Latvia Correspondence: Vilnis Frishfelds ([email protected]) Abstract. Diurnal oscillations of water level in Gulf of Riga are considered. It was found that there is distinct daily pattern of diurnal oscillations in certain seasons. The role of sea breeze, gravitational tides and atmospheric pressure gradient are analysed. The interference of the first two effects provide the dominant role in diurnal oscillations. The effect of gravitational tides is described both with sole tidal forcing and also in real case with atmospheric forcing and stratification. The yearly 5 variation of the declination of the Sun and stratification leads to seasonal intensification of gravitational tides in Gulf of Riga. Correlation between gravitational tide of the Sun with its radiation caused wind effects appears to be main driver of oscillations in Gulf of Riga. Daily variation of wind is primary source of S1 tidal component with a water level maximum at 18:00 UTC in Gulf of Riga. Effect of solar radiation influences also K1 and P1 tidal components which are examined, too. 1 Introduction 10 A distinct feature in Gulf of Riga is diurnal oscillations of water level despite tidal influence is negligible in Baltic sea. These oscillations are especially expressed in a relatively calm and sunny spring days. The amplitude of oscillations can reach 10 cm of water level in May, see Fig.
