The paper presents the possibilities of using modern online sources of satellite information in the tasks of monitoring the ecological and navigational- hydrographic situation and building on their basis methods and information technologies to reflect the state of marine waters and operational forecasting of changes in this state. For the tasks of monitoring the ecological and navigational- hydrographic situation, one of the most convenient and informative is the marine environment monitoring service COPERNICUS (CMEMS). This service collects and presents data on observations of spatio-temporal variability of sea water temperature and salinity values, streams parameters, etc. by using specialized artificial satellites Sentinel-1 and Sentinel-2, which intended for use in the mission of a dual satellite with high viewing frequency and high resolution. CMEMS provides, on a regular and systematic basis, information on the physical condition, variability and dynamics of the oceanic and marine ecosystems. The principle of measurement uses natural microwave emissions on the sea surface, which vary depending on the degree of roughness of the sea surface. You can get the parameters of wind direction, atmospheric water vapor, rain speed, sea ice (age, concentration and limit), the length of the snow cover and the water content in the snow.
