Mystery Sheen in Lease Block MC-252, September 2012, Gulf of Mexico off LA.

This hotline is being started for new reports of sheen of unknown origin in and near lease block Mississippi Canyon 252. This incident is likely related to reports in August 2011 (See incident #8345, Aug2011). Although the source of these sheens may be the wrecked BP Macondo Well, this relationship has not been established at this time. Activities include daily overflights sponsored by BP, with USCG or NOAA observers on board intermitently. BP is sending a vessel to the area with an ROV to investigate the potential source.
