North Sea, DIVAnd 4D 6-year seasonal analysis of Water body chlorophyll-a 1980/2021 v2023 [time][depth][lat][lon], 0.1°, 1982-2018

North Sea - DIVAnd 4D 6-year seasonal analysis of Water body chlorophyll-a 1980/2021 v2023. Moving 6-year analysis and visualization of Water body chlorophyll-a in the North Sea. Four seasons (December-February, March-May, June-August, September-November). 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 2.7.9. 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.
