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.

The Drifting Buoys GDAC -Global Data Assembly Centre- is the repository of surface drifters data. Both NRT -Near Real Time- and DM -Delayed Mode- data are available on the GDAC. Drifters report generally trajectories, sea-surface temperatures, atmospheric pressures at sea-level, as well as sea-surface salinity or sub-surface temperature in the ocean top layer.

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.
