Some Results
Blue dots is the current deployment. Red dots is the daily average from ESTOC time-series. Grey dots is the time-series . Left wind rose is the current deployment, right wind rose is the total time-series. A vector presentation of the wind is the figure at the left side of the roses

WP 10 – Service Activities
Annual Cycle of pH – SensorLab (ESTOC & E1-M3A)
ACHIEVED A COMPLETE ANNUAL CYCLE USING A NEW SENSOR. COMPARISON WITH A SIMILAR PH ANNUAL CYCLE ACHIEVED AT THE E1-M3A (ANOTHER FIXO3 OBSERVATORY) OBTAINING SIMILAR PROPORTIONALITY SST AND PH RANGES AT ESTOC THAN THAT FROM THE GREECE OBSERVATORY. IN ADDITION THE DATA FROM THE SENSOR ARE EASILY HARMONIZED WITH THE HISTORICAL DATA AT ESTOC.

Winter Salinity Anomaly – EL NIÑO => +NAO
MAXIMA in SST anomaly
21 January >1.23ºC
24 January >1.24ºC
THE MAXIMA IN SST ANOMALY DETECTED IN WINTER 2016 COINCIDES WITH SIMILAR VALUES FOUND DURING WINTER BOTH CORRESPONDS WITH THE LAST TWO STRONGEST EL NIÑO EVENTS. A RECENT NOAA PRESENTATION SUPPORTS THIS VARIABILITY DUE TO POSITIVE PHASE OF NAO
