REPORT DATE: 06-08-2021 REPORT TIME: 0815 UTC REGION: GULF OF MEXICO SUB REGION: N/A AREA/BLOCK: MAIN PASS 153 IMAGE DATE: 06-07-2021 IMAGE TIME: 1546 UTC DATA SOURCE: PLANETSCOPE MODE: Multispectral RESOLUTION: 3 meter LOCATION: 29°08'48" N/88°48'16" W AREA: 0.73 square kilometers CONFIDENCE: Medium-High REMARKS: Possible oil was observed in satellite imagery. This anomaly is unconfirmed as oil. The anomaly was located approximately 22 nmi east of the mouth of the Mississippi River and measured approximately 1.9 nmi in length and up to 0.17 nmi in width oriented NW-SE. The anomaly had a dark, distinct appearance against its background. Winds at the time of the image were from the SSE at around 5 kts. The anomaly may have been related to NRC report #1307038, which reported a confirmed oil slick 2 nmi SE of this anomaly occurring 2 hours prior to the image time. UNCERTAINTIES: The anomaly could not be definitively associated with the NRC report as it was not attached to the reported location in that report, although the wind direction supports the possibility that the anomaly was related. Thus, confidence that this anomaly was oil was held at medium-high.
