REPORT TIME: 0245 UTC
REGION: GULF OF MEXICO
SUB REGION: N/A
AREA/BLOCK: GRAND ISLE    31
IMAGE DATE: 09-11-2018
IMAGE TIME: 1632 UTC
DATA SOURCE: LANDSAT8
MODE: Multispectral  
RESOLUTION: 30 meter
LOCATION: 29°02'58" N/89°53'40" W
AREA: 38.38 square kilometers (Updated 05/26/2020)
CONFIDENCE: Medium-High
REMARKS: Possible oil was observed in satellite imagery. This anomaly is unconfirmed as oil. The anomaly was approximately 9.41 nm NE-SW and 3 nm at its widest. The anomaly was black, thin oil, and white, relatively thicker oil, in color. There was feathering seen at the SW end of the anomaly. Winds were coming from the E-SE between 5-10 kts. The anomaly was given a Medium-High confidence due to no known point source or NRC report.



UNCERTAINTIES: There were three oil facilities within the anomaly. Also, due to cloud coverage, it was difficult to see the full extent of the anomaly. Lastly, ocean currents were moving in all directions which made it difficult to support the orientation of the anomaly.
