REGION: PACIFIC
SUB REGION: ALASKA
AREA/BLOCK: Gulf of Alaska  6610
IMAGE DATE: 09-16-2021
IMAGE TIME: 0237 UTC
DATA SOURCE: SENTINEL1A 
MODE: Interferometric Wide (IW) VV
RESOLUTION: 20 meter
LOCATION: 55°26'36" N/134°17'29" W
AREA: 1.59 square kilometers
CONFIDENCE: High
REMARKS: Possible oil was observed in satellite imagery. This anomaly is unconfirmed as oil. The anomaly was approximately 9.3nm in length and up to 0.3nm wide. The anomaly was dark in contrast along with sharp edges. The anomaly appeared to be originating from a vessel and slightly widened with distance, a common characteristic of a bilge dump. Winds at the time of the satellite imagery were W @ 10-15kts.

UNCERTAINTIES: The anomaly appears to be a classic example of a bilge dump, although there is a possibility that the anomaly was related to fishing activity off the Alaskan coast.
