oa Monitoring of the marine environment state of the northwestern part of the Black Sea

The report contains the results of océanographie research on the Ukrainian shelf in the northwestern part of the Black Sea carried out by scientists and specialists of the State Institution “Scientific Hydrophysical Centre of the National Academy of Sciences of Ukraine”. During the research it was accomplished the hydroacoustic survey of the seafloor with a total area of 70 sq. km. There were obtained a significant amount of hydrophysical data required for studying modern hazardous geological processes and redistribution of bottom sediments within the explored water area. These data are necessary for ensuring the possibility of monitoring of the marine environment state, in particular, in the interests of navigational and hydrographic support of navigation. As a result, a number of natural and artificial objects were identified. Also, the spatial distribution of micro- and mesoforms of the bottom relief and the structure of the upper part of bottom sediments were determined as well as their lithological classification was conducted. The obtained hydrophysical data were sorted and transferred to the Océanographie Data Bank of the National Academy of Sciences of Ukraine.
