The paper presents some results of a new web service for storing and processing oceanographic data as well as integrating data received with Lagrangian drifters into the See the Sea (STS) satellite monitoring system. The data for the web service was collected from 2016 to 2022 in scientific marine expeditions undertaken by Space Research Institute of Russian Academy of Science to study hydrophysical characteristics of coastal marine waters using contact and remote methods. The web service is used for data standardization and storage. Also, it allows exporting oceanographic data for input to STS. For preprocessing measurements from Lagrangian drifters, a Python program is presented that calculates additional parameters such as speed and distance traveled by drifters. This program also serves as a layer between archived data and the web service. The functionality of the web service is shown, allowing you to visualize measurements by coordinates on the built-in map through integration with the Mapbox service. The results of integration with STS are also presented. Here, the handler is integrated as a separate software module, allowing data to be visualized directly in the system interface. This enables conducting joint analysis of field measurement data, satellite images, and other thematic data. The results from the joint analysis in an STS environment have been used to study eddy dipoles in the coastal zone of the southeastern part of the Baltic Sea, off the coast of Kaliningrad, specifically to describe the 3D structure of currents within the eddy dipoles.
