 Method/Apparatus/Procedure:
   Saturate solution was prepared by equilibrating seawater with an excess of hydrocarbon for 24 hrs. in a constant temperature gyrotary chaker followed by 12 hrs. stationary period. A 100 mL-aliquot was extracted three times with n-hexane. The concentrated hexane extract was anlzyed by a gas chromatograph equipped with a flame ionization detector to determine the hydrocarbon concentration.
