HF Radar System

HF Radar System

COSYNA provides near real-time data from integrated observations and model results. The observations comprise a variety of in situ techniques (e.g. FerryBox, Gliders, Cabled Underwater Observatories) as well as remote sensing from shore by radar and from space by satellite. Key physical, sedimentary, geochemical and biological parameters are observed at high temporal resolution in the water column and the upper and lower boundary layers. COSYNA’s modelling part consists of nested models with different grid sizes for hydrography (salinity, waves, currents), for suspended matter and for biogeochemical and ecosystem processes. Sophisticated data assimilation procedures, i.e. continuous corrections of the models by observations, improve the reliability of now-casts and short-term forecasts. All data and plots are generally available for download through the data portal (http://codm.hzg.de/codm/). FerryBox data can be directly accessed via the data portal ferrydata.hzg.de where different vizualizaton tools are available (e.g. single transect, pool data along a certain transect for a longer time period or time-series at certain locations). Furthermore, all datasets can be exported in ASCII (tab separated tables) or NetCDF format and downloaded. COSYNA’s motivation is bridging the gap between operational oceanography and the various users of forecasts of the marine state. For further outreach to stakeholders and the wider community an app has been developed for the most common platforms.

The MONICAN web page provides access to real-time or archived measurements and operational forecasts of the oceanographic conditions prevailing in the Nazare Canyon area of influence. Near real-time measurements in the Nazare Canyon area are collected hourly by the MONICAN network. This network includes two multi-parametric platforms measuring waves, meteorogical parameters (wind, atmospheric pressure, air temperature and relative humidity), sea surface temperature and (for one of the platforms) water temperature in the upper 200m and currents in the upper 100m. The MONICAN network also integrates two coastal tidal stations providing sea surface level measurements in the ports of Nazare and Peniche , and one coastal meteorological station providing meteorological measurements in the area of Ferrel. The near real-time data is presented in graphical form (namely by combining observations and forecasts) and can be accessed in table form. Forecasts of the wave conditions affecting the coast of Nazare are also included.

POSEIDON is an operational marine monitoring, forecasting and information system for the Greek Seas. The observing component is a distributed infrastructure made by three coastal buoys (Saronikos buoy-SB, Heraklion Coastal Buoy-HCB and Athos buoy-AB) and one FerryBox (PFB). A calibration laboratory (see Chapter 2) is supporting the observing activities. The Athos buoy is equipped with meteo sensors and T, C/S, DO, fluorescence and turbidity sensors up to 100m in depth, is located in the coastal area in the Northern Aegean, representative of mesotrophic to oligotrophic conditions affected by circulation. Although coastal the depth of the water column allows deeper observations.
