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

North Sea - DIVAnd 4D 6-year seasonal analysis of Water body dissolved inorganic nitrogen 1980/2021 v2023. Moving 6-year analysis and visualization of DIN 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.

北海区域——DIVAnd 4D 六年季节性分析，水体内溶解无机氮（DIN）1980年至2021年（版本2023年）。北海区域DIN的动态六年分析与可视化。分析涵盖四季（十二月至二月、三月至五月、六月至八月、九月至十一月）。数据来源：SeaDataNet/EMODnet 化学数据网络观测数据。DIVA分析描述：采用DIVAnd（数据插值变分分析）工具进行的地理统计学数据分析，版本2.7.9。结果经过DIVAnd中的最小场选项处理，以避免插值结果中出现负值或低估值；包括L1（0.3）和L2（0.5）误差阈值掩码以及未掩码字段。深度维度允许在各个深度上可视化网格化场。
