EMSO-Azores Infrastructure description

  • Date of Deployment: 29 July 2010
  • Location: South of Azores, Lucky Strike
  • Type: Non cabled observatory
  • Distance from land: 200 nautical miles WSW from Faial
  • Maximal depth: 1700 m
Transmission buoy, BOREL2

Coordinates:  37.3 °N  and  32.28 °W

Short description: Borel is the surface buoy, relaying bi-directionally measurement data or commands between seabed and shore, through underwater acoustics and satellite. Borel holds a geodetic Global Positioning System and can host near surface ocean sensors.

  • AIS
  • Geodesic GPS
  • Iridium GPS modem n°1
  • Iridium GPS modem n°2
  • Meteorological station
  • Buoy management unit 1, COSTOF2
  • Buoy management unit 2, COSTOF2
SeaMoN West

Coordinates: 37.291 °N   and  32.279 °W

Short description: SeaMoN West is the station moored in the lava lake. Here, an EGIM serves the local set of sensors, generic and specific, and provides bi-directional acoustic communication with the surface buoy. SeaMoN West is dedicated to environmental (EOVs) and geophysical observations.

EGIM with

  • Optode O2
  • Turbidity sensor
  • ADCP
  • Hydrophone
  • CTD
  • Pressure gauge
  • Management unit, COSTOF2

serving additional sensors

  • Short-period Ocean Bottom Seismometer, OBS
SeaMoN East

Coordinates: 37.29 °N  and  32.28 °W

Short description: SeaMoN East is the station positionned at the base of the Tour Eiffel active edifice. It serves the local set of sensors and provides bi-directional acoustic communication with the surface buoy. SeaMoN East is the EMSO-Azores ecological node.

Oceanographic mooring

Coordinates: 37.299 °N  and  32.276 °W

Short description: The oceanographic mooring is anchored  at Lucky Strike and allows the study of hydrographic processes such as as internal tides or passing mesoscale eddies. The mooring is autonomous and is serviced during the maintenance cruise.
