Sheen Reports; off Bolinas, CA

off Bolinas, CA | 2016-May-08

Initial Notification: On May 8, 2016, USCG Sector San Francisco contacted the SSC to relay two separate (but nearby) sheen reports offshore of Bolinas CA. The first sheen report from a charter fishing vessel was of a 1 mile x 100 yd rainbow sheen at 0930 hrs, but no orientation description. The second report from the Tug Arthur Brusco was of a N/S oriented sheen approximately 12 NM from the earlier report and within the vessel Traffic Separation Scheme outside the entrance to San Francisco Bay. USCG requested a hindcast trajectory to determine if the two sheen reports might be related and to narrow down the potential source(s).
