Mechnikov National University popup.description1 The purpose of the work is a comprehensive study of the places of discharge of deep fluid flows on the seabed to create a comprehensive and consistent geographic information system (GIS) to determine their location, the evaluation of certain places by degree of danger (weak, medium, strong and very dangerous) for surface and underwater navigation in the economic zone of Ukraine and the nearby deep water of the Black Sea. popup.description2  The project was aimed at a comprehensive study of the threat posed by the discharge of methane-saturated deep fluid flows (DFF) on the seabed to the safety of navigation. The discharge of DFF can lead to spontaneous combustion explosions similar to weapons explosions, change the density of water, which can cause the destruction or disappearance of ships. DFF erupt due to tectonic disturbances in the form of siphons, fiery plumes and mud volcanoes, which are concentrated in the deep Black Sea and coincide with shipping routes, including civilian and military vessels, including NATO. The aim of the project was to create a comprehensive geographic information system (GIS) to identify DFF discharge sites and assess their hazard to navigation in the economic zone of Ukraine and adjacent areas of the Black Sea. The tasks included the creation of a geological, geophysical and hydrological data base, as well as the use of satellite monitoring to identify anomalous zones. The development of a GIS based on spatial unity and the method of superposition of information layers allowed to create model images of the DFF unloading areas and assess the degree of their threat to navigation. The results include the creation of a regional GIS to assess the hazard of DFF on the seabed, which allowed detecting anomalous changes in the water column and atmosphere, such as explosions or changes in water density, which could threaten the safety of ships. The model images are based on scientifically based features, which made it possible to effectively detect and predict dangerous areas using satellite monitoring. The practical value of the results lies in the assessment of the threat of unloading of DFF and in the creation of a reliable system for the prevention of dangerous phenomena, which is of strategic importance for the safety of navigation.
