Instruments Specification sheet

Main purposes

The Instrumental Oceanographic Buoy is designed to accomodate the use of many instruments in order to satisfy the oceanographic researcher's needs. These instruments, offered as options, are grouped into three main categories:

Ouvrir avec Adobe ReaderOptical parameters

- Measurement of the light spectrum level in air and water
- Measurement of the concentration of coloured biological matter dissolved in sea water

Meteorological parameters

- Wind direction and speed
- Atmospheric temperature and humidity
- Atmospheric pressure

Oceanographic parameters

- Water temperature
- Water salinity, density and conductivity
- Measurement of the water flow at many programmable depths

A software is designed to help the researcher interpret information from the buoy. This information is sent to a land station via UHF modem or satellite or a combination of UHF and Internet. The researcher can set at which interval he wants to receive information from the buoy.
