The calibration facilities include a fully equipped Laboratory with a special designed large calibration tank, two smaller glass tanks and a number of reference sensors and equipment for temperature, salinity, chlorophyll-a, turbidity and dissolved oxygen sensors calibration.
Data have been collected during the POSEIDON network operation and are easily accessible through a web interface to the system's database. The database is updating on a daily basis offering full access both to archived and recent data. The user has also access to multiple metadata information regarding the buoys sensors, location, operational period and other combined information.
Fixed moorings is an oceanographic onshore or offshore platform. A fixed mooring consists of steel wire or synthetic rope which holds the registered sensors and associated with one or more buoys to provide sufficient buoyancy to keep the mooring upright.
Ocean gliders are autonomous underwater vehicles used for ocean science. They travel in the sea water by changing their buoyancy and attitude in order to successively dive up and down in order to sample the sea water and collect oceanographic data. Gliders typically profile in a saw tooth pattern from the surface to 500-1000 m depth, travelling 3-6 km in the horizontal at a speed of about 1 km/h in every dive cycle.
FerryBox is an operational method to continuously measure physical, chemical and biological parameters on board of ships-of-opportunity. FerryBox is a through-flow system installed on board of a ship-of-opportunity (ferry, cargo ship or research vessel) providing data of important marine parameters in near real time. The sensors installed offer the opportunity to measure salinity, temperature, pH, CO2, and dissolved oxygen.
The infrastructure is coordinated by the School of Civil Engineering of the NTUA and comprises five components:
The Hydrology team is involved in the installation and operation of tele-hydrometric networks since 1998, during the implementations of the TELEFLEUR and DEUKALION projects. In the current project, the team will re-evaluate the existing tele-hydrometric network of DEUKALION and will identify the needs for its upgrade and expansion.
The Institute of Marine Biological Resources and Inland Waters of HCMR will assess the existing automatic water monitoring networks in Greece and their upgrade and expansion needs, while it will propose suitable river locations for installation of new monitoring stations. Water quantity and quality monitoring stations will be installed that will continuously record important parameters such as: pH, water temperature, dissolved oxygen, electrical conductivity and water level.
Ocean and Weather Forecasting systems use mathematical models in order to describe ocean and weather systems by using numerical methods. Numerical methods are made by assimilating the dynamic, energy, physical processes of the ocean and the atmosphere. Assimilation models provide short term forecast for atmospheric, wave and hydrodynamic conditions of the marine environment. The institute of Oceanography, HCMR in provides an open access to the following forecasting systems:
Scientific research in coastal environments is of high priority and great significance for Greece, since they are highly stressed and vulnerable areas prone to degradation from direct human activities.
