Satellite Source: Landsat 7
Mode: Multispectral
Resolution: 30 meter
Image Date & Time: 05-14-2018 1632 UTC

Confidence: High
Issue Date: 05-15-2018

Region: Gulf of Mexico
Location: 29�11'14" N, 89�56'35" W
Coverage Area: 17.12 km^2

Remarks:
**Please be advised that this report is for imagery captured the previous 
day, but which did not become available until today**
Possible oil was observed in satellite imagery. This anomaly is unconfirmed 
as oil. The anomaly is believed to correspond to NRC report #1212055. 
It was located about 4 nm S of Grand Isle State Park, measured approximately 
6.6 nm long and had an average width of 1 nm. In sunglint, the anomaly 
appeared silvery/white indicative of relatively thicker oil, while it 
appeared black in areas of thinner oil. It's orientation was supported 
by 10-15 kt surface winds from the NE at the time of the image. No oil 
facilities are located near the slick, but several pipelines converge 
in the vicinity. 

Uncertainties:
Due to the scanning error in Landsat-7 imagery that led imagery drop-out 
areas, we only have medium confidence in the slick's true areal extent.
