REPORT DATE: 07-07-2025 REPORT TIME: 1240 UTC REGION: GULF OF AMERICA SUB REGION: N/A AREA/BLOCK: HIGH ISLAND A376 IMAGE DATE: 07-06-2025 IMAGE TIME: 1648 UTC DATA SOURCE: SENTINEL2B MODE: Multispectral RESOLUTION: 10 meter LOCATION: 27°57'16" N/93°41'04" W AREA: 10.57 square kilometers CONFIDENCE: Medium-High REPORT MAP/GIS FILES: https://www.ospo.noaa.gov/products/ocean/marinepollution/ REMARKS: Possible oil was observed in satellite imagery. This anomaly is unconfirmed as oil. A shimmery slick was observed in true-color satellite imagery, its appearance influenced by sunglint. It displayed two distinct levels of brightness, with the brighter region potentially indicating areas of thicker oil. The anomaly featured well-defined edges and stood out distinctly from surrounding features, including known false positives in the area. The slick measured approximately 4.3 nautical miles in length and 0.8 nautical miles at its widest point. Winds were from the Southeast at about 10 kt at the time of the image. UNCERTAINTIES: The slick's source could not be identified despite pipelines and an oil facility located nearby, according to GIS data available at the time of this report.
