North Sea DIVA 4D analysis of Water_body_nitrate

This gridded product visualizes 1960 - 2014 water body nitrate concentration (umol/l) in the North Sea domain, for each season (winter: December – February; spring: March – May; summer: June – August; autumn: September – November).


It is produced as a Diva 4D analysis, version 4.6.9: a reference field of all seasonal data between 1960-2014 was used; results were logit transformed 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.


Every step of the time dimension corresponds to a 10-year moving average for each season.


The depth dimension allows visualizing the gridded field at various depths.
