Current status of the Observatory (October 2014)

• Position: 29,181º N; 15.585º W• ODAS Buoy + Mooring line• Sensors at ODAS buoy:Meteo.: Barometric Pressure, air temperature,

Relative humidity, PAR and Wind speed and direction.

Ocean: sea surface temperature, salinity, dissolved oxygen, pH, pCO2, Chlorophyll, turbidity.

• Sensors at mooring line (100m depth): Temperature, salinity, dissolved oxygen, chlorophyll and current

• people involved: Xabier Remirez, A. Cianca and other technicians

WP 2 / WP3 – Technological & Procedural HarmonisationTask 2.1:Review of the current status of all fixed observing sitesTask 3.1: Assessment of procedures

Operating Scheme/Schematic (with time intervals)Pre- Deployment (5 months)- Maintenance buoy and sensors (cleaning and repairs)-Calibration for sensors (if needed)-Sensor and mooring line purchase (if needed).-Sensor validation prior to fix in the buoy (water tank and laboratory measurements)- On land test prior coastal-site deployment

Coastal-site Deployment15- 30 days)-after deployment, the buoy is recovered, buoy and sensors are cleaned for ESTOC deployment- Sensor maintenance or replacement (if needed)

ESTOC-site Deployment2 - 5 days

(ship-time availability and weather conditions)

On the Field (1 day)Casual visit because of communication problems. For that, it is necessary very good weather and ship availability.Pre- Deployment: sensor validations – land test – coastal-site test

- Design issue: a bad weight distribution produced a slight tilting angle. Redistribution of weight.-Over expected power consumption from pCO2 and pH sensor. Change in the configuration of the sensors.- Difficulties with meteorological sensor validation (calibration from manufacturers). Only a comparison with sensors from AEMET was available.
