The Internet version of the interactive geoinformation system names as «Crimea Sea Coast» based on javascript programming language and the modern open library «leaflet» is described. Development of a product supposed to use of the modern vector graphics technologies, such as D3, Flot and other superstructures over javascript.
The main attention is paid to operational representation of full-scale results observations with assessment of Crimea coastal zone dynamics in general. Options of such approach are already realized with use of data on measurement of coast line position of the northwest coast now. In addition, the system reserves the special section described the basis and results of the implementation of the previously developed cadastral assessment of the Crimea beaches, including their recreational areas, economic assessment of recreational resources, as well as the results of comprehensive interdisciplinary monitoring of Sevastopol Bay environmental condition for the period from 1998 to the present, including a cartographic representation of the geographical elements of the region as a whole. The results of monitoring allow to realize visualization of spatial distributions of hydrological,hydrochemical and hydrobiological characteristics of the bay sea environment in the digital format defined by user, to perform the construction of vertical distributions, and also to calculate some ecological indexes. The final version of the system is expected to be posted on the official website of Marine Hydrophysical Institute.

Results of the analysis of a long-term data set, including fields of significant waveheights of the surface wave components, and mixed (total) wave field in the Black Sea arepresented. The data set was collected on the basis of retrospective calculations using the MIKE21 SW spectral wave model with the atmospheric forcing based on the ERA-Interim data in theperiod from 1979 to 2017. A criterion is used to isolate the swell waves from the initial wave dataset that takes intoaccount the wave age. We used the experimental data to develop a regressionrelationshipshowing that the maximum possible wave height can exceed the significant waveheightapproximately one and a half times. Analysis of the spatial distribution of wave heights intheBlack Sea suggests that a possibility exists that significant wave height of storm waves can beas high as 12 m. This result indicates that the actual heights of maximum waves in the Black Seacan reach 18—19 m. Three regions are distinguished on the basis of the wave potential. Thetimesof manifestation of extreme situations in these regions are different: in the southwestern part ofthe sea, extreme storm situations occur, as a rule, in December—January; in the region south ofthe Crimea Peninsula this happens in February; in the northeastern part of the sea they occur inNovember. It was also found that the south-southeastern and eastern parts of the sea are mostaffected by swell.
