Abstract
Heavy fuel oil from the 2007 M/V Cosco Busan oil spill on November 7, 2007
contaminated 26 miles of shoreline throughout the San Francisco Bay area. Past studies on
heavy fuel have focused on those components detectable with gas chromatography (GC), the
maltenes; however, up to 57% of the carbon released in a heavy oil spill is contained in the
non-GC amenable, operationally defined as its solublities in solvent, asphaltene and resin
fraction. Over the past two years Massachusetts Institute of Technology/Woods Hole
Oceanographic Institution Joint Program graduate student Karin Lemkau has performed a
comprehensive examination on oil samples from the M/V Cosco Busan spill to determine the
fate of both asphaltene and maltene fractions of this heavy fuel oil in the (marine)
environment overtime. In this study, we compared oil samples from three sites on Angel
Island, California located in San Francisco Bay. These samples were collected in August of
2008 and July of 2009, 295 and 616 days after the spill respectively. The collected oil was
analyzed to determine fate and weathering of spilled oil and calculate the change in weight
percent of asphaltenes overtime. The results from these efforts indicate that the composition
of heavy fuel oil changes with time and that by day 616 oil contained, on average, a higher
weight percent of asphaltenes than oil collected 295 days post spill.
