Fixed-Point Open Ocean Observatories, a European FP7 Infrastructure Project, started in September 2013
  The EuroSITES team have joined the 23 sites and 29 partners of FixO3

Poseidon E1-M3A

Latitude and Longitude: 35.66N, 24.99E
Depth: 1440m
Oceanographic Region: Aegean/ Cretan Sea, Mediterranean

History of the Site:


Operated since January 2000 this is an extremely oligotrophic area where dense waters with intermediate and deep characteristics are formed. In 2007 an ocean time-series was added which has been evolved during the EuroSITES programme.
