Fig. 4: DIN:DIP (the ratios of dissolved inorganic nitrogen to phosphorus) and DIN:DSi (the ratios of dissolved inorganic nitrogen to silicate) in submarine groundwater discharge (SGD) and river16,52,69,70 constituents along the coastlines.

From: Large scale submarine groundwater discharge dominates nutrient inputs to China’s coast

Fig. 4

Dots and texts in red or blue represent groundwater or river. Blue, yellow, and green areas indicate water enriched in DIN, DIP, and DSi, respectively. Most groundwater samples are enriched in DIN and DSi. Hence, SGD will further push China’s shelf waters towards P limitation. Source data are provided as a Source Data file in Supplementary Data 1.
