REPORT DATE: 04-30-2019
REPORT TIME: 1515 UTC
REGION: GULF OF MEXICO
SUB REGION: N/A
AREA/BLOCK: GRAND ISLE    33
IMAGE DATE: 04-30-2019
IMAGE TIME: 0001 UTC
DATA SOURCE: SENTINEL1A 
MODE: Interferometric Wide (IW) VV
RESOLUTION: 20 meter
LOCATION: 29°01'53" N/89°55'26" W
AREA: 0.64 square kilometers
CONFIDENCE: Medium-High
REMARKS: Possible oil was observed in satellite imagery. This anomaly is unconfirmed as oil. The anomaly had good contrast with its background and was broken into two sections with the largest segment extending about 1 NM long by 0.4 NM wide at its widest. Additionally, the anomaly appeared to originate from a point source. Winds were from the ESE at 10 KT at the time of the image, which did not correlate too well with the spread of the anomaly. Considering the above factors, we have MEDIUM-HIGH confidence in this assessment.

UNCERTAINTIES: There is a possibility that the anomaly may be associated with a substance other than oil. Winds did not align well its orientation.
