The "See the Sea" (STS) is an information system developed by the Spase Researth Institute of the Russian Academy of Sciences (IKI RAS, Moscow, Russia), to study various processes and features in the ocean and sea using diverse satellite data. The STS is the toolkit to work with remote sensing data and to analyze results. Its key advantage is in an ability to perform a complex analysis of data varying in physical character, spatial resolution and units of measurement. The system also provides access to long-term (over 20 years) distributed archives of satellite data for the entire Eurasia from 1995 to the present, including Synthetic Aperture Radar (SAR): Envisat ASAR, ERS-2 SAR, Sentinel-1A, -1B; optical systems: MODIS Terra/Aqua, MERIS Envisat, TM/ETM+/OLI Landsat-5/7/8 satellites series, MSI Sentinel-2A, -2B, OLCI Sentinel-3 and hyperspectral data from Hyperion and HICO systems. Currently, the volume of the archive is over 2 PB and it is updated with real time data daily. In addition, the multi-year weathe data are available on-line. The STS is an open system capable to incorporate any required data (such as altimeter data, buoy data, in situ measured data, and other).
