REPORT DATE: 04-18-2021 REPORT TIME: 0300 UTC REGION: GULF OF MEXICO SUB REGION: N/A AREA/BLOCK: ATWATER VALLEY 489 IMAGE DATE: 04-17-2021 IMAGE TIME: 1628 UTC DATA SOURCE: SENTINEL2A MODE: Multispectral RESOLUTION: 10 meter LOCATION: 27°27'53" N/89°40'44" W AREA: 1.44 square kilometers CONFIDENCE: Medium REMARKS: Possible oil was observed in satellite imagery. This anomaly is unconfirmed as oil. The anomaly had a sharp contrast to its surroundings and displayed characteristics of thicker oil in regions of metallic appearance. Cloud cover partially obscured the anomaly, and there were no potential sources in the immediate area. The anomaly had a feathering signature which was indicative of the southwesterly winds at 5 knots. At its widest, the anomaly measured approximately 0.32 nmi, and it measure approximately 4.4 nmi in length. UNCERTAINTIES: A false positive intersected the anomaly, and there were some natural sources of oil in the region. In addition, there was no nearby likely point source subsequently reducing confidence.
