Raising knowledge about the marine environment in the Bay of Varna

One of the main guidelines set by the EU in the objectives of coastal zone development is to increase knowledge about the state of the marine environment. The accumulation of new knowledge and data is the scientific basis for creating improved economic models that are environmentally friendly and offer efficiency in the use of coastal zone resources, as well as a model for their renewal and environmentally friendly use. economy "and the application of the principles of the circular economy suggest a sound basis of accurate data and analysis based on multidisciplinary research. In recent decades, the needs of the community for various maps of the seabed and the coastal zone have increased significantly in different scales and directions (geomorphological, geological, risk factors, bottom substrates, etc.) integrated with other environmental elements. At present, for Bulgaria, and in particular for the Gulf of Varna, there are no complete and detailed coastal zone models prepared at a modern level and using innovative technologies. As a basis for all these maps, the high resolution digital terrain model (MDR) is used, which is of paramount and decisive importance for accurate mapping and subsequent proper planning of the development of the area in accordance with modern and environmental practices. This project proposal seeks to develop just such a digital relief model of the Gulf of Varna, integrated with biodiversity and ecology data, to become a scientific base in management decision making that fulfills and meets the objectives set out in the Marine Strategy of the Republic Bulgaria and the EU's founding documents for the development of the maritime and coastal zone. The choice of a region is conditioned by the presence of numerous unstructured archival data from the Institute of Oceanology - BAS Fund from the period before 1989, and at the same time by the lack of up-to-date ones, which makes them unusable.
