Coastal Sea Level Monitoring in the Mediterranean and Black Seas

Spanning over a century, a traditional way to monitor sea level variability by tide gauges is – in combination with modern observational techniques like satellite altimetry – an inevitable ingredient in sea level studies over the climate scales and in coastal seas. The development of the instrumentation, remote data acquisition, processing and archiving in last decades allowed for extending the applications towards a variety of users and coastal hazard managers. The Mediterranean and Black50 seas are an example for such a transition – while having a long tradition for sea level observations with several records spanning over a century, the number of modern tide gauge stations are growing rapidly, with data available both in real-time and as a research product at different time resolutions. As no comprehensive survey of the tide gauge networks has been carried out recently in these basins, the aim of this paper is to map the existing coastal sea level monitoring infrastructures and the respective data availability. The survey encompasses description of major monitoring networks in the Mediterranean and Black55 seas and their characteristics, including the type of sea level sensors, measuring resolutions, data availability and existence of ancillary measurements, altogether collecting information about 236 presently operational tide gauge stations. The availability of the Mediterranean and Black seas sea level data in the global and European sea level repositories has been also screened and classified following their sampling interval and level of quality-check, pointing to the necessity of harmonization of the data available with different metadata and series at different repositories. Finally, an assessment of the networks’ capabilities60 for their usage in different sea level applications has been done, with recommendations that might mitigate the bottlenecks and assure further development of the networks in a coordinated way, being that more necessary in the era of the human-induced climate changes and the sea level ris

TOURIST INDUSTRY GROWTH PRESSURE ALONG THE BULGARIAN BLACK SEA COAST

Abstract Coastal zone representing the boundary between sea and land is a highly dynamical and sensitive area that comprises a large variety of natural resources. Population growth in the littoral causes rapid urbanization of the coast, development of infrastructures, transport system and so on. Therefore, coastal ecosystems experience pressure and become vulnerable to pollution, habitat degradation and loss, overfishing, and increased coastal hazards. Accelerated tourism development during the recent years is an extra risk factor for the Bulgarian Black Sea coastal zone. Considering that the coastal zone is a limited and very vulnerable land area, the high population increase due to tourism is one of the most hazardous factors for coastal zone sustainability. Although tourism growth and coastal development give rise to a number of economic benefits, they also could lead to loss of habitat, green space, and biodiversity

EXTENSION D'ARGO DANS LES ZONES CÔTIÈRES PEU PROFONDES ET EXTENSION DES COMMUNAUTÉS RÉGIONALES (PROJET EURO-ARGO RISE)

International audienceThe recent technological advances of the autonomous oceanographic monitoring platforms has allowed observations of unknown regions and dynamic processes that play a key role in the physical environment and marine ecosystem functioning. Under this context Euro-Argo RISE project aims towards the investigation of Argo extension in shallow coastal areas of European marginal seas (Black Sea, the Baltic Sea and the Mediterranean Sea) as well as the seasonally ice-covered areas of the high latitudes (Arctic Ocean). Different fl oat confi gurations are tested whilst the development and implementation of operational systems to control the platforms are performed. Test deployments under Euro-Argo RISE have provided indications for the best settings, the optimization of fl oat missions and the improvement of the life expectancy and the sampling effi ciency in shallow coastal areas. In addition, guidelines and best practices for operating fl oats in seasonally ice-covered areas are provided. The reinforcement and expansion of the Argo infrastructure at a regional scale is performed by approaching the regional research community (also through the organization of workshops and political events) with the aim of: promoting Argo data, cooperation at sea, collaboration in technical activities, sharing best practice, knowledge and expertise

Types and impacts of maritime hydraulic structures on the Romanian – Bulgarian Black Sea coast: setting-up a common catalogue for GIS-based coastline classification

Abstract: The present study is a basic part of developing a joint GIS-based coastline typology to determine various geomorphic types of landforms (natural/ anthropogenic) along the Western Black Sea coast. The main purpose is to develop a web geomorphic classification for this part of the Black Sea coast, covering both Bulgaria and Romania. The research is focused on inventory the multipurpose maritime hydraulic constructions (harbour and coastprotection types) built along the Bulgarian-Romanian coast and to point out on their functions and effects. Setting-up of a common catalogue to all types of maritime structures for the Bulgarian-Romanian part of the Western Black Sea coast will help the establishment of unified technical terminology. The results are an important step to create a common classification criteria based on geomorphologic and engineering research approaches for identifying natural landforms and technogenous objects along the both coastlines

The Black Sea Physics Analysis and Forecasting System within the Framework of the Copernicus Marine Service

This work describes the design, implementation and validation of the Black Sea physics analysis and forecasting system, developed by the Black Sea Physics production unit within the Black Sea Monitoring and Forecasting Center as part of the Copernicus Marine Environment and Monitoring Service. The system provides analyses and forecasts of the temperature, salinity, sea surface height, mixed layer depth and currents for the whole Black Sea basin, excluding the Azov Sea, and has been operational since 2016. The system is composed of the NEMO (v 3.4) numerical model and an OceanVar scheme, which brings together real time observations (in-situ temperature and salinity profiles, sea level anomaly and sea surface temperature satellite data). An operational quality assessment framework is used to evaluate the accuracy of the products which set the basic standards for the future upgrades, highlighting the strengths and weaknesses of the model and the observing system in the Black Sea
