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

Source and Purity of Materials:
   (1) Acenaphthene: from Aldrich Chemical Co. of 99% purity and doubly distilled from distilled methanol, n-Hexane: doubly distilled in glass, seawater: collected off Scripps Pier and was filtered twice through 0.22 µm membrane and twice extracted with n

Estimated Errors:
   Solubility: ± 2%
   Temperature: ± 0.1°K
