Jrap#5 has been preparing for intensive period starting March 2017. The observation plan will be detailed in December 2016 – January 2017.
At FMI/SYKE, new instruments have been tested for continuous pH and pCO2 measurements. In addition, methods for analyzing DIC and alkalinity from discrete water samples have been taken into use.

In the Cretan Sea (Eastern Mediterranean), a pH sensor (sensorlab) was deployed by HCMR in collaboration with IOCAG (M. González Dávila) in July 2016, at the location of the POSEIDON E1-M3A buoy, allowing continuous pH measurements transmitted every 3 hours. In addition, discrete water samples have been taken at monthly frequency next to the pH sensor, for analyzing DIC and alkalinity.
The intercomparison of the different instruments used by Jerico-next partners is planned to take place in 2018, after the completion of the intensive period.
