    "Title": "Black Sea - DIVA 4D 6-year seasonal analysis of Water body silicate 1970\/2018 v2021",
    "Abstract": "Moving 6-year analysis of Water_body_silicate in the Black Sea for each season: spring (March-May), summer (June-August), autumn (September-November), winter (December-February). Every year of the time dimension corresponds to the 6-years centred average of each season.\n6-years periods span: from 1970-1975 until 2013-2018\nDepth range (IODE standard depths): -200.0, -150.0, -125.0, -100.0, -75.0, -50.0,-40.0, -30.0, -20.0, -10.0, -5.0, -0.0.\nData Sources: observational data from SeaDataNet\/EMODnet Chemistry Data Network.\nDescription of DIVA analysis: Geostatistical data analysis by DIVA (Data-Interpolating Variational Analysis) tool. GEBCO 1min topography is used for the contouring preparation. Analysed field masked using relative error threshold 0.3 and 0.5 DIVA settings: signal-to-noise ratio and correlation length were estimated using data mean distance as a minimum (for L) and vertically filtered. Log transformation was used in the analyses. Background field: the data mean value is subtracted from the data. Detrending of data: no, Advection constraint applied: no. Units: umol\/l.\nThe entire set of related maps can be found in the viewing service: http:\/\/ec.oceanbrowser.net\/emodnet\/",
