REPORT DATE: 10-02-2021 REPORT TIME: 0815 UTC REGION: PACIFIC SUB REGION: CALIFORNIA AREA/BLOCK: Southern California 6389 IMAGE DATE: 10-02-2021 IMAGE TIME: 0158 UTC DATA SOURCE: SENTINEL1A MODE: Interferometric Wide (IW) VV RESOLUTION: 20 meter LOCATION: 33°38'17" N/118°05'12" W AREA: 3.04 square kilometers CONFIDENCE: High REMARKS: Possible oil was observed in satellite imagery. This anomaly is unconfirmed as oil. The anomaly was centered approximately 4.5 nmi W of Huntington Beach, CA in the coastal Pacific Ocean, and measured approximately 2.8 nmi in length and up to 0.7 nmi in width. The anomaly was dark against its background with sharp edges. Winds at the time of the image were from the WNW at around 5 kts. The anomaly was co-located and likely associated with NRC report #1318437, which was a report of a sheen of unknown type or origin. The image time was approximately 45 minutes after the time of the NRC report. UNCERTAINTIES: The anomaly extended to and possibly beyond the edge of the image. Although there were numerous vessels within immediate proximity to the anomaly, none were clearly associated with the anomaly. These factors prevented the possible identification of a point source. Still, the NRC report allows for high confidence that this was oil.
