REPORT DATE: 04-29-2021 REPORT TIME: 0220 UTC REGION: GULF OF MEXICO SUB REGION: N/A AREA/BLOCK: N/A IMAGE DATE: 04-28-2021 IMAGE TIME: 1632 UTC DATA SOURCE: LANDSAT8 MODE: Multispectral RESOLUTION: 30 meter LOCATION: 29°30'54" N/89°26'55" W AREA: 0.43 square kilometers CONFIDENCE: Medium-High REMARKS: Possible oil was observed in satellite imagery. This anomaly is unconfirmed as oil. The slick had a strong contrast to the surrounding environment and was approximately 0.89nm in length and 0.10nm in width. The slick appeared to have thicker oil throughout the entire anomaly extents. Winds at the time of the image were from the SE and between 10-15kts, which aligned well with the slick. The slick was located in the Breton Sound area. UNCERTAINTIES: The slick did not appear to be associated with an oil facility and no known reports were observed around the slick which limited our confidence to medium-high for this assessment.
