Organic nitrogen and organic phosphorus concentrations bays of the White Sea

Concentrations of organic and mineral nitrogen and phosphorus in waters from different types of bays were determined during summer of 1987. Content of organic nitrogen in surface waters reached 80-97% of total; content of mineral phosphorus was 60-100%. Concentrations of N_org and P_org in deep waters decreased to 70 and 40%, respectively. Distribution of organic matter in the bays was controlled by river run-off.

1987年夏季，研究人员对不同类型海湾水体中的有机态氮、矿质态氮、有机态磷与矿质态磷的浓度进行了测定。表层水体中有机态氮占总氮的比例可达80%~97%，矿质态磷的占比为60%~100%。深层水体中的有机态氮（N_org）与有机态磷（P_org）占比分别降至70%与40%。海湾内有机质的分布主要受河流径流调控。
