attribute NC_GLOBAL abstract String Moving 6-year analysis of Water body silicate in Black Sea for each season: winter (December-February), spring (March-May), summer (June-August), autumn (September-November). Every year of the time dimension corresponds to the 6-year centered average of the season. 6-years periods span from 1980-1985 until 2016-2021.\nData Sources: observational data from SeaDataNet/EMODNet Chemistry Data Network.\nUnits: umol/l.\nDIVA analysis: The computation was done with the DIVAnd (Data-Interpolating Variational Analysis in n dimensions), version 2.7.9, using GEBCO 30sec topography for the spatial connectivity of water masses.\nThe horizontal resolution of the produced DIVAnd maps grids is 0.05 degrees.\nThe vertical resolution is 15 depth levels: 0, 5, 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 125, 150, 200m\nThe horizontal correlation length: 75km.\nThe vertical correlation length (in meters):  twice the vertical resolution (10, 10, 20, 20, 20, 20, 20, 20, 20, 20, 20, 50, 50, 100, 100).\nThe error variance (epsilon2): 1 \nAn anamorphosis transformation was applied to the data: threshold value=200.\nBackground field: not used.\nQuality control of the observations was applied using the interpolated field: QCMETHOD=3 and visual inspection (Observations with residuals outside the minimum and maximum values of the 99% quantile were discarded from the analysis after thoroughly visual inspection)
