Gulf of Mexico

(and download our GPF flight tracks here!)
Today we flew a long and carefully planned route over Gulf of Mexico waters south of Louisiana, in order to look for surface oil slicks. We had planned the flight for Sep 17, but weather and travel forced us to delay til today. The route would cover 22 known sites, all based on our previous sightings and known natural seeps, including three recently reported sights, and of course that area of chronic interest -- MC252 and surroundings, home to BP's infamous well and the Macondo reservoir. We found what we were looking for, and much that we had hoped not to find.
In short -- the natural seeps remain, some of them narrow lines of "pancakes" of oil and some of them wide areas of shimmering surface slicks. Pollution cleanup debacles like the chronic Taylor Energy site less than 15 miles off the coast of Louisiana remain, egregious sites covering miles and miles, and flowing substantially still, as evidenced by the heavy patches of rainbow sheen. What we did not expect was to see that kind of rainbow sheen and substantial amounts of fresh-looking oil around the Macondo reservoir. But find it we did.
The stuff within a few miles of MC252 looked like this (GPS waypoints 0411, and a slick between waypoints 0415 and 0416 from our flight log below):
(That's our nose wheel in these still photos taken from the video camera that looks slightly forward from a belly viewer in our plane, which we view and control via a remote monitor.) A video of what we saw in this area is included below.
Here is a large-scale map of our planned route (pink) and our actual flight path (blue), together with a close-up of the eastern part of our route (near the Macondo). We went first to the site of the chronic Taylor Energy oil leak south of Breton Sound, then to the vicinity of MC252 and the DWH disaster of 2010, then southwestward nearly 175 nautical miles to check out locations of known natural seeps and of recently documented surface oil slicks, then headed back to Lakefront Airport via Grand Isle, LA.
As you know from our previous articles, our actual flights go where "the stuff" is, so the actual paths are usually circles and spirals and meandering paths that track the oil or the animals or whatever it is that we're tracking. You can read from these actual paths almost as clearly as you can from our GPS waypoints, just where "the stuff" was. The actual GPS coordinates are given in our Flight Log appended below.
Here is a short video of the oil seen near the Macondo. This rainbow sheen was seen within a few miles of the site of the 2010 BP disaster; the slick was at least one nautical mile (2 km) long and on average about 400-500 meters wide. This video was taken from a small video camera looking through the belly of our plane, at between 800' and 1000' above the water. The small narrow line of oil you see at the end of the video is the way sites of known natural seeps tend to look (except for some which cover much wider areas of surface). The rainbow nature of this slick suggests a much more substantial flow of oil than is associated with most of these natural seeps. (See, e.g., the photo of the natural seep in Green Canyon, about 175 miles southwest of here.) Many more photos can be found in the galleries below.
Our flight log gives more detailed info on the appearance and positions of the oil we saw; it is appended below the photo galleries. Our GPS tracks can be downloaded here; those will tell you exactly where we were at any given time.
Here are more photos of what we saw near our gps waypoint #411, at approximately 1211 CDT:
Now, about 15 nm (30 km) east of here, around our gps waypoint #412, at 1223 CDT, we saw another slick, with less rainbow sheen and more of the milky luminescence. Here is a video of that, followed by some photos of it:
Eight miles southwest of here, near "MC294" and the site of a known natural seep, this is what we saw:
Finally, a good while later and about 160 nm still farther southwest, in Green Canyon, we checked out other known abundant natural seeps, most famously the one located in "GC600."
You will note from the flight log that we saw a lot of oil -- about 24 distinct sightings. We don't have photos of it all, but we do have many more photos than are shown here, and over the next week or so, we'll post the remaining photos of the additional slicks.
MORE PHOTOS from Oct 05 ADDED TODAY (20121016):
Here are more photos from Oct 05. The first is a distant view of the chronic Taylor Energy pollution site, only about 12 miles offshore from Louisiana. (More photos of the Taylor slick can be seen in the article from our Oct 06 flight for whale sharks, and in numerous other of our articles -- just search the keyword on this website). The next eight photos are all of the surface oil in the Macondo area. (The photo filenames will tell you the date, time, and area of each photo.) The next three after that, taken around 1227 CDT, are about 15 nm east of the Macondo. Then, at 1245CDT, we have two more photos of the Macondo area, as we circled back to the west. And one photos taken 3 miles northwest of the Macondo. You can start to see what natural seeps look like, compared to what we were seeing in the Macondo area and eastward!
To see more natural seeps, look at the next six photos, those whose filenames say MC294, MC709, GC600, or GC767. Some of these are expansive surface slicks, but we typically do not see the rainbow sheen that we are seeing in the Macondo area, indicating less of a flow. Finally, in the last photo you'll see a platform slick about 20 miles south of Timbalier Bay -- an all too common site around platforms in the Gulf of Mexico.
