The quality of biological data has gained recognition as an essential part of international monitoring programmes, in response to the demand for strategic environmental evaluations such as the EU WFD, the MSFD and informed decisions for environmental sound management. The paper presents the results of an intercalibration exercise among four Black Sea phytoplankton laboratories (NIMRD-RO, IBSS-UKR, IO-RAS - RUS and IO-BAS - BLG) conducted under SESAME FP6 Project with the objectives: 1) to assess the degree of comparability of phytoplankton and chlorophyll a data produced by routine in-house methods; 2) to formulate recommendations for progress towards harmonization of the research methodology in the Black Sea. The statistical treatment of the results reveal that at the level of total phytoplankton abundance and biomass as well as chlorophyll a the data were in a good agreement, while for some taxonomic classes (Prymnesiophyceae and small flagellates) the differences were significant. The counted sample volume proves essential for detection of species diversity and the methods of species specific biovolume measurements - for the total biomass. As a follow up Guidelines for QC/QA of phytoplankton data and check-list with suggested shapes for biovolume calculation were produced under UP-Grade Black Sea SCENE FP7 Project that offer key options for progress. © Published by Central Fisheries Research Institute (CFRI) Trabzon, Turkey.

The Southern Sector of the Romanian shore, from Cape Midia to Vama Veche (the Bulgarian border), stretching about 74 km of cliffs shore, having 70 m maximum high, mainly protected with small beaches at the slope basis, is in a continuous erosion process. The work presents certain results obtained with UAV (Unmanned Aerial Vehicle), mapping activities extended on the southern unit of the Romanian shore, providing certain terrain data, represented by the Ortho-mosaics, Digital Surface Models (DSM), refined 3D models of coastal facilities and waterfront slopes. The integration of new mapping techniques with various data provided by the old topographical and hydrographical surveys, developed on the coastal area, can offer the basis of precise spatial changes and evolution trends, supporting the continuous improvement of the coastal protection and planning strategies. Thus, the shoreline changes of the cliffs coast will be studied based on a new approach, taking in consideration the physical and outsized calculus limitations of the UAV survey technology. © SGEM2015.

The present paper addresses the rapid change processes of the ecological status from the coastal eco-systems, induced by the fast sedimentation/erosion processes, determined by the combined action of the hydrological regime of the Danube and marina agitation factors, increasing under the influence of the current climate change. The paper presents some results of a substantiation study on the hydro-geological and hydro-bio-geomorphic, river, delta, marine and coastal environment, as well as the ecosystem state assessment of this natural and built area from the Romanian Black Sea shore. The analysis/modeling actions and the simulation of the natural hydro-geomorphological processes, as well as the analysis processes modified/induced by the anthropogenic factor, including the probable impact/evolution assessment of the deltaic ecosystem/coastal affected ecosystem were developed, in order to highlight the viable solutions that enable an efficient and sustainable management and renaturation of the Romanian coastal vulnerable areas. The evolution of the marine agitation factors, which are of crucial importance in the deltas and lagoons formation, extending a multi-criteria complex analysis on the response processes of the coast to the action of the marine agitation factors with ecological impacts from interested area, is highlighted. Accordingly, the final results of the hydro-bio-geo-morphological processes study of the shallow area allow the intervention opinions and the efficient management of the biotic and abiotic resources from the coastal system, based on the changes knowledge at different scales of the climatic conditions determined by the environment and reflected in different coastal ecosystem status indicators. © SGEM2015.

In situ waves measurements, as well the experimental researches, encompasses complex approaches on the waves fields development, especially related to the marine and coastal waves propagation and interactions towards safety navigation, were become progressively important in the last decades. The present works on the marine waves hydrodynamics, as a response processes of climatic changes, takes in to consideration the offshore operations and port management activities, and it is extended through several in situ and modeling approaches focused on the waves and currents regime, in the specific conditions of the western Black Sea Basin, afferent to the Romanian coast Certain results on the evolution of the main hydrodynamics indicators/parameters at medium and short term for the interest zone will be emphasized. The modeled vs. measured quantities of significant waves parameters, where analyzed on its seasonal/annual and multi-annual variance in relation with its importance on the maritime port management operations developments in the transitional area of the Romanian shore. © SGEM2015.

The new implementations of the coastal protection works within their ongoing extensions are producing several changes/reconsideration of the initial Master Plan. Thus, it will take into consideration the new changes of the hydrodynamic regime in several ways. The coasts will most likely change and the plan must be completed and revisited, based on the modeling of coastal rapid evolution process on long term and special event occurrence. The aim of the master plan is to slow and stop the rapid changes, taking place at this moment, bringing the coast to a its ideal form to prevent future erosion processes and to make cost effective the artificial beach nourishments on long term. The occurrence of extreme phenomena is approached in an innovative manner to cope to the new hydrodynamic intricate regime, to produce better and more realistic scenarios. Thus, the rate of decomposition needs to be recalculated to fulfill the new Master plan. Optimizing the work flow for valid prediction of an ideal long-term shoreline changes is vital to diminish the erosion and the variations of coastal stability. © SGEM2014. Source
