The paper presents a web service developed for processing and storing field measurements and the results of the integration of acoustic Doppler current profiler (ADCP) data into the See the Sea satellite monitoring system. Data for the web service were collected during 2016–2022 scientific marine expeditions conducted by Space Research Institute of the Russian Academy of Sciences to study the hydrophysical characteristics of coastal marine waters by contact and remote methods. The web service is intended for standardization and subsequent export of measurements to external systems. To pre-process measurements from ADCP, a Python program is used to remove data outliers and streamline the archived data to the web service. To visualize full-scale measurements, contour graphs can be drawn for physical parameters, using filters and averaging, thus allowing visual assessment of the situation by the selected date of expedition. Also, we present the results of ADCP data integration into the STS, where work with the data is implemented as a separate software module. This makes it possible to visualize ADCP data directly on the STS interface display and therefore conduct analysis of field measurements jointly with satellite images and other thematic data. This functionality has been employed to study eddy dipoles. In particular, a combined analysis of satellite data and concurrent in situ measurements, performed in STS, enabled determination of the characteristic features of their 3D structure.
Keywords: See the Sea satellite monitoring system, STS, in situ measurements, satellite data, acoustic Doppler current profiler, ADCP, web service, data processing and storage, data visualization, vortex processes, eddy, Sentinel-2 MSI, Landsat-8 OLI
