Mediterranean Sea DIVA 4D analysis of Water_body_pH

Moving 10-years analysis of pH at Mediterranean Sea for each season :

- winter (January-March),

- spring (April-June),

- summer (July-September),

- autumn (October-December).

Every year of the time dimension corresponds to the 10-year centered average of each season.

Decades span from 1959-1968 until 2005-2014.

Observational data span from 1930 to 2014.

Depth range (IODE standard depths): -1500.0, -1400.0, -1300.0, -1200.0, -1100.0, -1000.0, -900.0, -800.0, -700.0, -600.0, -500.0, -400.0, -300.0, -250.0, -200.0, -150.0, -125.0, -100.0, -75.0, -50.0, -30.0, -20.0, -10.0, -5.0, -0.0.

Data Sources: observational data from SeaDataNet/EMODNet Chemistry Data Network.

Description of DIVA analysis: Geostatistical data analysis by DIVA (Data-Interpolating Variational Analysis) tool. Profiles were interpolated at standard depths using weighted parabolic interpolation algorithm (Reiniger and Ross, 1968). GEBCO 1min topography is used for the contouring preparation. Analyzed filed masked using relative error threshold 0.3 and 0.5.

DIVA settings: A constant value for signal-to-noise ratio was used equal to 1. Correlation length was optimized and filtered vertically and a seasonally-averaged profile was used.

Logarithmic transformation applied to the data prior to the analysis.

Background field: the data mean value is subtracted from the data.

Detrending of data: no.

Advection constraint applied: no.
