REMARKS: Possible oil was observed in satellite imagery. This anomaly is unconfirmed as oil. The anomaly appeared to extend southward from a vessel located approximately 30 nmi N of Unalaska, AK. The anomaly measured approximately 17.5 nmi in length and up to 0.45 nmi in width, widening with distance from the vessel. The anomaly was distinct from its background and surroundings, and appeared to exhibit feathering. Winds at the time of the image were 5-10 kts from the S.


UNCERTAINTIES: The wind direction did not line up well with the orientation of the apparent feathering. There were no known reports of oil slicks in the area.
