REPORT DATE: 06-12-2021 REPORT TIME: 0330 UTC REGION: GULF OF MEXICO SUB REGION: N/A AREA/BLOCK: WALKER RIDGE 430 IMAGE DATE: 06-11-2021 IMAGE TIME: 1628 UTC DATA SOURCE: SENTINEL2B MODE: Multispectral RESOLUTION: 10 meter LOCATION: 26°31'49" N/90°17'03" W AREA: 5.12 square kilometers CONFIDENCE: High REMARKS: Possible oil was observed in satellite imagery. This anomaly is unconfirmed as oil. The anomaly was approximately 6.13 nmi in length and approx. 0.86 nmi at its widest. It had high contrast against its surrounding environment. The dark colored anomaly widened with distance which is an indicator of a possible bilge dump. Winds near the time of the image were coming from the SE between 5-10 kts. UNCERTAINTIES: It is possible that the fragment further up north was part of the bilge dump since it was the widest of the all segments and there was no other possible point source in the vicinity.
