Gulf of Mexico, 50-150 miles southeast of New Orleans, LA

The R/V Endeavor (a UNOLS vessel operated by the University of Rhode Island) has been busy in the Gulf off of Louisiana again, studying natural and not-so-natural oil seeps and the status of the ocean floor.  They contacted us a few days ago to advise us that they found themselves sitting in a surface oil slick, in the vicinity of the Deepwater Horizon (DWH) "spill" site of April 2010.  Today was the first day we could arrange to fly out there, and yes, we did indeed find oil slicks in that good old MC252 quadrant.  We hope to learn from their samples whether the surface oil there is from long-existing natural seeps, or whether it is from the reservoir that unleashed its contents just 2.5 years ago.

Here are maps of today's 3.9-hour flight.  We flew to the DWH site via Breton Sound, to check out some suspiciously slick-looking areas near there, according to MODIS satellite data.  We didn't stop to look around carefully, but we didn't see any obvious surface oil in this area. But what was unusual was how high the water seemed to be. The usual islands were scarcely visible. Fortunately, we had heard that the tides were unusually high today, so we were relieved not to have to think that this situation was some permanent consequence of Hurricane Isaac.

On reaching the DWH site, we immediately saw two surface oil slicks, separated from each other by about a mile.  The first one was about a third of a mile long and about 100 meters wide, the other a bit smaller.  The water was choppy, and it was difficult to get good footage of the slicks from the air.  We also saw another slick a bit northwest of here on our way back. Here are a few still photos of those slicks. More are in the photo galleries below.

All platforms in this area were flaring today. We went as far southwest as the BP "Thunderhorse" platform, which was also flaring. There was a supply boat there (the Kore Chouest) and a clearly visible, substantial oil slick extending westward several hundred meters, perhaps caused by something they were discharging. (See video of this also, below.)

Returning back via the Chandeleur Islands, we came across some very strange-looking expanses of dark murky water, huge expanses of it stretching for miles and miles, with "fuzzy" jagged lines, not like ordinary convergence lines. We saw similar things in this area in the spring of 2011, except at that time it was dark reddish-brown, but today it was dark green.  This is probably what the folks at Skytruth.org had told us they had been seeing on the MODIS satellite imagery in this area.  We hope someone more knowledgeable about these things will head out and sample it or advise us what it is!  See the video and more photos of this strange dark green stuff below.

The unusually high tide was manifest at the Chandeleurs also.  At least we hope that's what it was, else Isaac really tore up this lovely chain of islands.  For today, there was not much to see of them; they looked more like shallow sandbars than islands. Lovely Breton island barely remained above water.

For the entire trip, we barely saw a bird, and we saw no wildlife in the water at all.

It was a great pleasure to be in the air and over the water and beautiful wetlands again today.  But feelings were mixed, as it is always sad to see so little wildife when we remember seeing so much here in 2010.  We wonder what it was like before 2010 and wish we could have seen it then!

More photos and videos from today are shown below the Flight Log.  Our GPS Flight tracks can be downloaded by clicking on the main menu item "Flight Tracks" -- or clicking here.  

Many thanks to the folks at Skytruth.org for noticing the strange MODIS satellite images south of the Chandeleurs, and to FlightlineFirst at New Orleans' Lakefront airport for helping make this On Wings Of Care flight possible!
