Components |
POSEIDON system is made up of the following main components :
-
Network of observation buoys
-
Data transmission telecommunications systems
-
Operational center with forecasting numerical models
|
Observational buoys |
|
|
WAVESCAN buoy
|
|
|
|
The SEAWATCH WAVESCAN buoy is a versatile instrumentation platform that has been designed to provide less drag and large buoyancy making it well suited for deep offshore locations or areas of strong current forces.
|
|
|
SEAWATCH buoy
|
 |
|
The SEAWATCH buoy is a stable instrumentation platform that has less buoyancy than the WAVESCAN and it is well suited for medium water depths.
|
|
|
SEAWATCH Deep Sea Module
|
|
|
|
The SDSM is a seabed observatory with acoustic communication which allows the integration of additional modules into existing buoy based systems.
|
|
 |
|
|
The buoys are equipped with sensors that monitor:
-
Air-pressure
-
Air-temperature
-
Wind speed and direction
-
Wave height, period and direction
-
Sea surface salinity and temperature
-
Surface current speed and direction
In two sites additional deep physical and biochemical observations are made:
-
Salinity and temperature at depths 20-1000 m
-
Chlorophyll-A and light attenuation at 20-100 m
-
Dissolved oxygen at 20-100 m
-
Current speed and direction at 20-50 m
-
Radioactivity
-
Radiance - Irradiance
