ALBATROSS, Deep sea mooring

Coordinates: 42° 48.3730’ N ; 006° 01.6098' E

Short description: ALBATROSS, the Autonomous Line with a Broad Acoustic Transmission for Research in Oceanography and Sea Sciences, is a standalone deep sea mooring dedicated to the long term monitoring of hydrological and biogeochemical properties. The data are transmitted along the inductive cable of the mooring line and through acoustic to the MII.

MII, Instrumented junction box

Coordinates: 42° 48.3730’ N ; 006° 01.6098' E

Short description: The MII, Instrumented junction box, hosts sensors and has acoustic communication capacities to recieve the information from the mooring ALBATROSS. The MII is wired to the shore through the cable of the astrophysics detector KM3NeT.

Short description: The BJS, Secondary Jonction Box, is a sea floor extension to the cabled neutrino telescope MEUST. It is devoted to geosciences  and environmental science.

Shipborne profiles and sampling

Coordinates: 42° 48’ N ; 006° 05’ E, 24

  • CTD, oxygen and fluorescence profiles, beam attenuation (down to 2460m)
  • Sea water sampling: nutrients, O2, AT-CT at 12 depths (5,50,100,200,300,500,750,1000,1500,1750,2000,2460)
  • Under water vision profiler (UVP5) : particles and zooplankton profiles
  • Zooplankton net (0-200m) : Zooplankton sampling
Data policy and access

  • Real time: for data transmitted throught the KM3net Cable
  • Near real time transmitted data: data aquired by the profilers
  • Periodically recovered data: Free access, previous year data treated by the quality control process, recovery on a yearly basis
