Aquaculture sector holds significant potential for ensuring food security, supporting economic growth, and contributing to the sustainable use of marine resources within the European Union (EU), aligning with the UN Sustainable Development Goal 14 Life Below Water . However, the potential of aquaculture is constrained by multilevel challenges, including environmental externalities, regulatory complexities, and social acceptance. These challenges are exacerbated by underlying tensions between goals for growing the ...

From time immemorial, the oceans, seas and their coasts have been the cradle of human civilization and still play a vital role in the lives of millions of people, indirectly affecting all of humanity. The phenomenon of coastalization suggests that our reliance on and dependence from marine and maritime sectors will grow, and their sustainable development is a topical challenge. The Blue growth strategy addresses this issue on a Pan-European level, fostering research and innovation with regards to marine environmen...

Lakes on the Black Sea coast are the direct result of soil erosion and marine or hydrographic accumulations, consequence of the specific evolution of the nearby sea basin. They depend on the variations in groundwater levels, rainfall or other hydraulic surface sources. In recent decades, as a result of many small, local earthquakes, some deep currents have appeared. Lakes as origins, are of fluvial-marine estuary, lagoons or artificial. Many of them are tourist attractions, due to the specific microclimate establi...

Waves represent the most important factor in the evolution of the coastal zones. One of the main causes leading to the wave formation is the movement of the air masses. A particular influence on the wave agitation regime in the littoral sector is exerted by the shore configuration, water depth, bottom relief and the formation of ice cover in winter. The scope of this paper is to analyze the historical data on the wind and waves in the Danube discharge area. The emphasis is on the maximum values of wave heights and...

The paper aims to assess the macrobenthic diversity and habitats distribution in front of the Danube mouth along a depth gradient on the Romanian Black Sea shelf. During the reference 60 - 70?s period the benthic community diversity accounted for 75 species. In the 80?s (starting of eutrophication period) this has sharply decreased to 45 species as result of the ecological collapse due to economic development of the riverine Black Sea countries?. However, the area is naturally under the influence of the riverine i...

The sea coasts and estuaries are especially exposed to the oil pollution harmful influence as they frequently suffer from oil spills relating to the tanker accidents, port and off-shore activities. The objective of the present research is to examine the rates of spilled fuel oil natural destruction on geographically different seacoasts and to assess their self-cleaning capacity. For this purpose, a number of contaminated sectors of the Atlantic coasts of France and Spain (areas of пїЅErikaпїЅ and пїЅPrestigeпїЅ ta...

This article identifies the special features of the preliminary designing of RoPax vessels. The hull geometric parameters have been defined as well as the functional parameters of the designed vessel, in consideration of the volume/capacity criterion. The preliminary assumptions have been adopted. T he preliminary calculations algorithm has been proposed, a statistical analysis has been conducted of hull geometrical properties of 20 similar vessels and the relationships reflecting the connections amongst them were...

A review of extreme storm events along the Bulgarian Black Sea coast is of interest for wide spectrum of readers – oceanographers, meteorologists, engineers, economists, decision makers and stakeholders. Reasonable management of the coastal zone demands a reliable and timely forecasting of storm events and evaluation of the related potential damages and economical losses. This paper focuses on the heavy storm of February 1979. The aim of the study is reconstruction of all stages of the storm on the basis of avai...
