REPORT DATE: 10-03-2021
REPORT TIME: 0730 UTC
REGION: PACIFIC
SUB REGION: CALIFORNIA
AREA/BLOCK: N/A
IMAGE DATE: 10-03-2021
IMAGE TIME: 0149 UTC
DATA SOURCE: SENTINEL1B 
MODE: Interferometric Wide (IW) VV
RESOLUTION: 20 meter
LOCATION: 33°35'44" N/117°56'18" W
AREA: 6.03 square kilometers
CONFIDENCE: Medium-High
REMARKS: Possible oil was observed in satellite imagery. This anomaly is unconfirmed as oil. The anomaly was located in the Pacific Ocean just off the coast of Newport Beach, CA and measured 7.8 nmi in length and up to 0.7 nmi in width in multiple parts. The anomaly had a darker appearance against its background compared to areas of wind sheltering and other false positives in adjacent parts of the image, with poorly-defined edges. Winds at the time of the image were from the NW at around 7 kts. This anomaly is believed to be related to Hotline #10361 "Oil report off Huntington Beach, CA" and NRC report #1318442 associated with an MPSR from 24 hours ago.

UNCERTAINTIES: The poorly-defined edges of the anomaly, as well as its proximity to land, allow for the possibility that this was a false positive. However, the previous report and the earlier confirmed presence of an oil slick in the area allow for medium-high confidence that this anomaly was oil.
