Satellite Source: Sentinel 1A
Mode: Interferometric Wide (IW) VV
Resolution: 5x20 meter
Image Date & Time: 04-23-2018 0001 UTC

Confidence: Medium
Issue Date: 04-23-2018

Region: Gulf of Mexico
Location: 2857'49" N, 8914'40" W
Coverage Area: 0.79 km^2

Remarks:
Possible oil was observed in satellite imagery in South Pass 28. This anomaly 
is unconfirmed as oil. The anomaly dimensions were 1.5 NM long by 0.5 
NM wide at its widest. The anomaly was amidst numerous oil facilities 
and had very good contrast with its background but had no discreet point 
source and did not align well with the W winds. There is a possibility 
that this could be biogenic material or cleaning agents. Considering all 
of the above factors we have MEDIUM confidence in this assessment.

Uncertainties:
The anomaly could be biogenic material or a cleaning agent.
