抄録: The concentrations of copper organic compounds dissolved in sea water in the westcrn North Pacific, Indian and Southern Ocean were determined from the collection of XAD-2 resin followed by atomic absorption spectrophotometry. The average concentration of total copper dissolved in surface water is 0.5 μgl^<-1> for the western North Pacific, 0.7 μgl^<-1> for the Indian Ocean and 1.3 μgl^<-1> for the Southern Ocean, respectivly; 60 to 90 % of this copper is organically bound. Most of the copper organic compounds are involved in neutral or basic organic compounds with a molecular size ranging from 2 x 10^3 to 2 x 10^4. The intimate correlation between the organically bound copper and the combined amino acids adsorbed on the XAD-2 resin indicate that the organic ligand to the copper organic compounds might be polymer organic matter. The composition of the amino of the metal organic compounds suggests that few species of amino acids are concerned with metal complexation. These amino acids are not free but in a combined states, in polypeptides or polynucleotides accompanied with carbohydrates.
