Sheen report; Off Point Piedras Blancas, CA

Off Point Piedras Blancas, CA | 2021-Jul-09

Initial Notification: On the morning of 09-JUL-2021, a sailing vessel reported a large area of sheen roughly 4.5 miles offshore and 11 miles NW of Point Piedras Blancas. The reporting party indicated that it covered a large area, extending “beyond what the eye can see, it took 15 minutes to sail… through and it is a rainbow sheen with sludge in it.” (from NRC Report No. 1310177). USCG Sector San Francisco contacted their NOAA SSC to discuss the report, as natural oil seeps are known to be in the area. A USCG overflight was scheduled and Sector SF was interested if NOAA NESDIS might have suitable satellite imagery covering that area.
