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

TENATSO - Tropical Eastern North Atlantic Time Series Observatory

Latitude and Longitude: 17.4N, -24.5W
Depth: 3600m
Oceanographic Region: Tropical Eastern North Atlantic

News: A sub-surface mooring has been in place since 2006. The site is visited regularly by research ships to take extra samples and download data.

 
 

Parameters measured:

The sub-surface mooring does not have near real-time capability but data are stored in the sensors and downloaded on maintenance cruises.
Parameter Depths measured (m) Sensor Frequency
