Satellite Source: Landsat 8
Mode: Multispectral
Resolution: 30 meter
Image Date & Time: 06-26-2018 1520 UTC

Confidence: High
Issue Date: 06-27-2018

Region: Atlantic Ocean
Location: 4006'02" N, 6955'03" W
Coverage Area: 2.43 km^2

Remarks:
Possible oil was observed in satellite imagery. This anomaly is unconfirmed 
as oil. The anomaly was connected to a repeat leak source wreck 1487, 
which was located about 68 nm south of Nantucket Island. The narrow oil 
slick was 6.9 nm long, and had a sliver appearance due to sunglint. The 
shape of the anomaly was not rounded, and it was distinguishable from 
the surrounding area. Confidence is high due to its characteristics and 
connection to a repeat leak source.

Uncertainties:
Due to the low wind area in the region, a more precise areal measure could 
not be attained.
