Gulf of Mexico
Yesterday morning, Transocean reported a 13,000-gallon (310-barrel) spill from their Deepwater Nautilus semi-submersible, which is currently drilling for Shell Oil in 7,200' of water about 26 miles southeast of the sunken Deepwater Horizon, in the Appomattox area. The spill was reported to be oil mixed with drilling fluid from a leak in a booster line. A "light surface sheen" was verified by the U.S. Coast Guard during an overflight. We arrived there a little after 11am and found two vessels: Akira Chouest and Emily Candies. The seas were too rough and visibility too poor to positively identify any surface sheen. But we can say with confidence that the many sightings of oil in the Macondo area on our last flight, December 09, and on this flight, are not associated with this drilling work.
Enroute there, and on our way back from there, we found more than we expected we would see with the poor atmospheric visibility and rough seas. Yesterday and today were the first days of decent flying weather for visual surveys in ten days, but visibility was still borderline due to low clouds and mist. Seas were 4 to 6 ft too, not great for spotting oil or marine life. But in winter here in the Gulf it's futile to wait for perfect blue-sky days, so we were up and early today.
NOTE: Unless noted, no photos or video provided by On Wings Of Care are "photoshopped" or otherwise altered in any way that could degrade accurate interpretation of what we observed.
(More maps of our flight paths, of varying resolution and depicting oil sightings by red circles with the most recent dates of the sightings -- e.g., 1220 for today, are given just above our Flight Log, at the bottom of this article.)
Despite very modest camera equipment and the poor atmospheric conditions, we saw a surprising amount. Our cameras saw somewhat less, but you'll get the general idea. Referring to our flight log appended below, we first saw a small patch of rainbow sheen north of Black Bay, about 10m (meters) by 30m in area (gps#1028 and 1-NRC in the flight log below, our first NRC incident report). Perhaps it is caused by a leaking pipeline or an absent vessel, we cannot tell from the air. As we approached the tip of the Delta, we flew over what looks like lots of tarballs (gps#130 below); we observed this on our last flight Dec 9 also. Today it seemed to us more likely to be vegetation (see photo below).
The next short but clear line of oil was among numerous rigs east and slightly north of the tip of the Delta (gps#131, 2-NRC), about 15m by 30m in area. It did not appear related to any particular rig; we wondered if it might be a leaking pipeline. We did not delay here to try to optimize lighting, and unfortunately our modest equipment did not pick it up well photographically, but it was significant enough that we reported it to the NRC, along with the other four significant sightings from today.
The third unmistakable and significant sighting of oil was in the Macondo area, about 13 nm southeast of the sunken Deepwater Horizon and about the same distance west of the Deepwater Nautilus (gps#0132, 3-NRC). We were hurrying to beat some cloud cover and get over to the Deepwater Nautilus, so we didn't take great video of this line nor follow it all of its way, but you'll get the idea. The same sort of lines we've been seeing for months -- narrow, maybe no wider than 10 m in most places, but at least 1 nm long. This was very near sightings from our last flights on December 9.
Things seemed quiet at the Deepwater Nautilus, though the visibility was so poor we really couldn't have seen much surface oil had it been there. Two ships were present, the Akira Chouest and the Emily Candies. We proceeded southwest from there to somewhat brighter skies, and soon spied what looked to be quite a bit of activity. Six vessels, approximately near two platforms but not obviously performing work associated with the platforms. At the Noble Amos Runner platform (whose position today decidedly differs from what we looked up on the internet at rodnreel.com, by the way), there were three vessels nearby: Joshua Chouest, Dino Chouest, and Touchdown. Just a few miles southwest was a BP platform we visited last December 9 whose only visible identification is "MC474A") with a helicopter on its pad, and three vessels gathered together a mile or so north of it: Ocean Intervention III, C Chariot, and Grant Candies. At the Na Kika platform to the south, all looked quiet and we saw no vessels.
Here are some videos of the Deepwater Nautilus and the other platforms and vessels. A gallery of photos of the various rigs and vessels is at the bottom of this article, just before the transcription of our Flight Log.
We headed back homeward at this point, since visibility was getting no better. To our surprise, we did find more oil on our way northward, at about 13 nm northeast of the sunken Deepwater Horizon (gps#0135, 4-NRC in the flight log below). We have found oil in this area every time we've flown since August of this year. Here we found a sheet of oil about 1.5 nm long (south-to-north), maybe 20m wide. The footage we took did not come out well. Disappointed by the poor visibility conditions, we headed directly homeward -- and then decided to take a very quick detour to see if the chronic leakage at the Taylor Energy site had been stopped yet.
The Taylor Energy site has been a big mess for some time, and we have yet to fly over that vicinity and not see some gnarly looking stuff. It moves around a bit, and today the most obvious lines, patches, and streamers were in an area almost 5 nm long and aout 3 nm wide (west to east). Some of the oil is quite weathered, showing itself as the typical wavy reddish-brown streamers, some of it dark and thick, some of it almost foamlike. The streamers themselves stretched 1-2 nm, and there were patches 100m wide. No vessels were working this area today.
Here are three videos of the Taylor Energy vicinity:
On our way home, we were treated to the beautiful site of hundreds of white pelicans alluded to above. Gathered closely together in a lovely heart shape, they were one of the prettiest and most refreshing sites we've seen in the Gulf for a while. May they survive and thrive!
Finally, here are photos of the various vessels and platforms noted above and in the Flight Log below.
