| 摘 要： | 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.

| Abstract: | The distributions of SiO3−Si, PO4−P, NO3−N and NO2−N concentrations in the seawater, ice and snow from 82 °45′21″W, 88 °01′20″N to the North Pole are reported and the exchange
of the nutrients among the seawater, ice and snow are discussed. The average concentrations of the nutrients in the seawater
near the North Pole were 4.9+2.4 μ mol/L for SiO3−Si; 0.6±0.10 μmol/L for PO4−P; 3.4±1.7 μmol/L for NO3−N and 0.13±0.04 μmol/L for NO2−N. The nutrient concentrations in the ice and snow in the North Pole were 0.20 and 0.65 μmol/L for SiO3−Si; 0.22 and 0.25 μmol/L for PO4−P; 1.6 and 5.8 μmol/L for NO3−N, 0.19 and 0.15 μmol/L for NO2−N.
