Moving 6-year analysis and visualization of Water body chlorophyll-a winter (dec-feb) in the North Sea. Data Sources: observational data from SeaDataNet/EMODnet Chemistry Data Network.

Description of DIVA analysis: Geostatistical data analysis by DIVAnd (Data-Interpolating Variational Analysis) tool, version 2.7.2. results were subjected to the minfield option in DIVAnd to avoid negative/underestimated values in the interpolated results; error threshold masks L1 (0.3) and L2 (0.5) are included as well as the unmasked field. The depth dimension allows visualizing the gridded field at various depths.
