Variables:
Ambient temperature: 15 - 25 °C
Salinity: 35 g/kg sln

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.
Estimated Errors:
Ambient temperature: ±0.1 K
Mass concentration (m/v) (1): ±2%
