Short summary
The anthropogenic nitrogen deposition has led to an increase in nitrate relative to phosphate in the upper oligotrophic waters; however, this anthropogenic nitrogen signal is unclear in the North Atlantic. We analyzed datasets from repeated measurements on meridional and zonal transects in the upper North Atlantic between the 1980s and 2010s and found that the anthropogenic nitrogen signal has been found only in the upper western North Atlantic.
