摘要：

Earlier workers have described a submarine gas seep in Norton Sound having an unusual mixture of petroleum-like, low-molecular-weight hydrocarbons. Actually, only about 0.04 percent of the seeping gas is hydrocarbons and 98 percent is carbon dioxide. The isotopic compositions of carbon dioxide (δ13CPDB = -2.7 per mil) and methane (δ13CPDB = -36 per mil, where PDB is the Peedee belemnite standard) indicate that geothermal processes are active here.
