摘要
The distributions of SiO<sub>3</sub>-Si, PO<sub>4</sub>-P, NO<sub>3</sub>-N and NO<sub>2</sub>-N concentrations in the seawater, iceand snow from 82°45′21″W, 88°01′20″N to the North Pole are reported and the exchange of thenutrients among the seawater, ice and snow are discussed. The average concentrations of the nutrients inthe seawater near the North Pole were 4.9±2.4μmol/L for SiO<sub>3</sub>-Si; 0.60±0.10μmol/L for PO<sub>4</sub>-P,3.4±1.7μmol/L for NO<sub>3</sub>-N and 0.13±0.04μmol/L for NO<sub>2</sub>-N. The nutrient concentrations inthe ice and snow in the North Pole were 0.20 and 0.65μmol/L for SiO<sub>3</sub>-Si; 0.22 and 0.25μmol/L forPO<sub>4</sub>-P; 1.6 and 5.8μmol/L for NO<sub>3</sub>-N, 0.19 and 0.15μmol/L for NO<sub>2</sub>-N.
The distributions of SiO_3-Si, PO_4-P, NO_3-N and NO_2-N concentrations in the seawater, iceand snow from 82°45′21″W, 88°01′20″N to the North Pole are reported and the exchange of thenutrients among the seawater, ice and snow are discussed. The average concentrations of the nutrients inthe seawater near the North Pole were 4.9±2.4μmol/L for SiO_3-Si; 0.60±0.10μmol/L for PO_4-P,3.4±1.7μmol/L for NO_3-N and 0.13±0.04μmol/L for NO_2-N. The nutrient concentrations inthe ice and snow in the North Pole were 0.20 and 0.65μmol/L for SiO_3-Si; 0.22 and 0.25μmol/L forPO_4-P; 1.6 and 5.8μmol/L for NO_3-N, 0.19 and 0.15μmol/L for NO_2-N.
