Mystery Sheen; Sasa Bay, Apra Harbor, Guam

Sasa Bay, Apra Harbor, Guam | 2015-May-15

Initial Notification: On May 15, 2015, the USCG Sector Guam has notified the NOAA SSC of a mystery sheen observed in Sasa Bay, Apra Harbor, Guam in the aftermath of Typhoon Dolphin. The sheen is reported to be approximately 30 feet by 300 feet and is blowing into Sasa Bay. The sheen is suspected to be from a 50-foot trawler sunken about 60 feet offshore on the Navy side of Apra Harbor. The vessel reportedly contains 1500 gallons of diesel onboard. Currently the release appears to be small and continuous. The area of sheen is of concern because of proximity to the Sasa Bay Marine Preserve and a large stand of mangroves.
