Available data

  • Wave data for any period from December 2018 to the current day (maintenance period with no data in late November and December 2019). All classical data from the reference state-of-art wave sensor are available (results of spectral analysis, results of wave-by-wave analysis, 1.28 Hz raw time-series)
  • Wind data from end of July 2018 to October 2019. 1 Hz time series and statistics are available for the following measurements: wind speed and direction
  • Weather data from end of July 2018 to October 2019. 1/600 Hz time series (10-minute average) and statistics are available for the following measurements: atmospheric pressure, air temperature and relative humidity
  • Inertial measurement unit data from end of July 2018 to October 2019. 2 Hz time series and statistics are available for the following measurements: roll, pitch and yaw angles, accelerations along axes x, y and z

Our offer

  • Statistical processing and joint analysis of metocean and inertial data
  • Support for the deployment of instrumentation at sea: specifications (site, instruments, etc.), design of floating supports, selection of components, purchase, installation, operation, etc.

Instruments

Wave buoy

  • Waverider DWR MKIII directional wave buoy (70 cm diameter)
  • Anchored in 60 m deep water at 43.316111°N 4.920361°E
  • Resolution: 1 cm / 1.5° of wave height/direction
  • Precision: < 0.5% of the measured value (in m) / 0.5°

Access real time data

Instrumented buoy

  • Special mark measuring buoy equipped with several instruments synchronised on a central acquisition unit for GSM/4G real time communication:
    • A 3D sonic anemometer (z at 3 m from the surface)
    • A weather station (air temperature, relative humidity and air pressure)
    • A GNSS-coupled 9-axis inertial unit
    • A tension sensor in the mooring line (at the buoy’s bottom)
  • Additional autonomous instruments soon to be installed on the buoy
    • Biofouling tracking sensor
    • Multiparameter probe
  • Anchored in 60 m deep water at 43.31425°N 4.921°E

The equipment described here is deployed on the MISTRAL test site which belongs to the VALECO Group. This site is located between the mouth of the Grand Rhône and Cap Couronne, 2.8 Mn from Port-Saint-Louis-du-Rhône.
