  <dc:description>&lt;p&gt;&lt;span&gt;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 (δ&lt;/span&gt;&lt;sup&gt;13&lt;/sup&gt;&lt;span&gt;C&lt;/span&gt;&lt;sub&gt;PDB&lt;/sub&gt;&lt;span&gt;&amp;nbsp;= –2.7 per mil) and methane (δ&lt;/span&gt;&lt;sup&gt;13&lt;/sup&gt;&lt;span&gt;C&lt;/span&gt;&lt;sub&gt;PDB&lt;/sub&gt;&lt;span&gt;&amp;nbsp;= –36 per mil) where PDB is the Peedee belemnite standard) indicate that geothermal processes are active here.&lt;/span&gt;&lt;/p&gt;</dc:description>
