2013 July 19--August 21
Gulf of Mexico, offshore Louisiana
Bouma & Ewing Banks east to Mississippi Canyon

Our latest four wildlife survey flights in the Gulf of Mexico were full of unpredicted and unwelcome weather obstacles, but our persistence brought us some interesting surprises! We found whale sharks, hammerhead sharks, pods of spinner and bottlenose dolphin, sperm whales, what we think are Cuvier's beaked whales, yellowfin tuna and other large fish, and a few of our favorite leatherback turtles. We didn't find the numbers we had hoped to find, but it was reassuring to find at least some where we would expect them to be at this time of year.

We also found plenty of surface oil slicks and sheen, which we've come to expect in this area of the Gulf of Mexico. Where there are oil slicks, we do not see much wildlife. In an area larger than 6000 square nautical miles that we've been surveying since last May, we have had a larger number of significant sightings of surface oil than of wildlife. "C'est la vie" in the Gulf of Mexico off the coast of Louisiana!

Here are just a few photos to give you a taste of what you'll find below.  First up are some interesting groups of dolphin, American egrets almost 120 nm off the coast, a hammerhead shark, sperm whales and a group of three beaked whales, and some whale sharks (apparently not in groups and frequently near active bait balls). Next is just one of many extraordinary patches of sargassum, some dark underwater plumes near the coast (algae or hypoxic areas?), a typical flare on an offshore rig, and the famous fisheries research boat from Louisiana Department of Wildlife & Fisheries (LDWF). (You saw that boat in the June 20 article, as the divers tagged 10 whale sharks that day of the 24 we found!) Following that are a few photos of some of the more egregious surface oil slicks, the last of which was just off the eastern coast of Louisiana near Grand Bay. And finally you'll see a few special views of the coastal wetlands and the city of New Orleans. 

Many more photos and videos are included below, starting with detailed maps of where we flew and where the most substantial sightings were, and ending with our transcribed flight logs showing the exact GPS coordinates for all of these sightings.  As always, you can download our GPS flight tracks from our main menu item called "Flight Tracks."

The Maps
Let's start with maps showing where we were on these four flights, and -- more importantly -- where all the wildlife were, and where all these photos and videos were taken!  The flight of July 19 -- our eighth survey flight since May 23, 2013 -- is shown in bright orange on these maps, and took us to the farthest west that we've ever flown, Bouma Bank, west of Ewing Bank. This was our sixth time to the Ewing Bank area since May. Some of the whale sharks that scientists had tagged on June 20 and earlier had surfaced and in this area, and we were hoping to find the large aggregations there that we did not see near Ewing Bank in the flights of June 30-July 2. We did find a few whale sharks, but mostly we saw dolphin, a few hammerhead sharks, one leatherback turtle, and some lovely sargassum. And oil. (We found oil on every flight -- seems to be the easiest thing to find out there.) Photos from July 19 are courtesy of Gary Gray of the Gulf Coast Research Lab. Our other spotter this day was our hometown hero and whale-shark scientist and tagger extraordinaire, Ms. Jennifer McKinney from LDWF.

On July 31, we returned to the Mississippi Canyon area for our fourth time since May; this flight is drawn in bright blue. Biologist Cijii Marshall from LDWF joined us as a spotter, together with an experienced bird spotter from Mississippi, Mr. Wesley Smith. We stayed to the eastern portion of the survey grid, following blue water and searching closer to where the tagging boat was.  We spotted one whale shark, but he (or she) dove before we could guide the tag boat. We saw some turtles, caught rare views of a sperm whale sleeping vertically, and watched a very active pod of well over 100 spinner dolphins.  We have three videos from this flight, two of sperm whales and one of this large pod of dolphins.

August 20 took us back to Ewing Bank for our seventh time; the flight track is shown in white. By now, you might be noticing that as weather permits, we try to make these flights around the full moon, the theory being that whale sharks and other opportunistic feeders are most likely to be eating near the surface when the smaller fish are spawning. Today we had a full plane with some very experienced spotters -- Terese Collins and Don Abrams from Mississippi joined Jennifer McKinneyof LDWF. Unfortunately, even the best spotter can't see well with 2-ft seas and somewhat marginal visibility due to cloud cover. Thunderstorms dominated the areas to our west and closer to shore. We found one whale shark near Diaphus Bank, several isolated sperm whales, a group of eight beautiful American (?) egrets flying far offshore, and a few groups of dolphin.  Alas, we also saw many large areas of surface oil sheen, as well as a few lines which could be natural oil seep lines or perhaps relatively small pipeline leaks. 

The next day, August 21, we returned to Mississipi Canyon with Jennifer McKinney and photographer volunteer Billy Dugger from Mississippi. Weather was a challenge again, and it forced us to remain in the eastern portion of this survey grid (see the white flight track in this area). We searched a bit east of the usual grid, because there had been reports of whale-shark sightings near the Devil's Tower platform. We did spot a large whale shark feeding vertically near a bait ball, and we saw several pods of dolphin -- in fact, later in the flight we were fascinated by three large pods very close together swimming very fast in a southerly direction. This was the day we saw the three whales that we think were Cuvier's beaked whales.

All of our photos are labeled with their lat/lon; and you can also find their position and time of sighting from our detailed flight logs at the bottom of this article. Profound thanks to all the volunteers who have joined us, to Jennifer and Wesley and Don for taking some great videos, to Gary and Terese and Billy for some fabulous photos, and all of the OWOC crew for making these flights successes in so many ways.  

The maps below give a qualitative idea of the sightings and their positions, with the icons symbolizing dolphins, whales, sharks, whale sharks, large fish (bait balls), sargassum, birds, and oil (red circles).  In a few days we'll post a short article summarizing all major sightings and locations for our flights in the Gulf since May 2013, with more detailed maps like these.

Here are those beautiful white American egrets flying hard against the wind, far offshore:

Sargassum and Sea Phenomena
We have come to appreciate the lines and patches of sargassum very much, since we learned what home and protection they provide to many species of marine life, especially young animals. Viewed from above, these long lines and large patches form exquisitely beautiful patterns as they move with the currents. Here are some photos and videos of sargassum and other interesting surface phenomena we  noticed:

Rigs and Vessels
For all that we dislike seeing surface oil pollution, it would be hard not to marvel at the technology, compactness, and manmade beauty of many of the offshore platforms, drilling rigs, and vessels. Here are photos and videos of some of the ones that caught our eyes and lenses:

20130820 - Rigs & Vessels

As we've said, there is never a scarcity of surface oil pollution to be seen when flying over the Gulf. Here are just a few photos and videos of the kinds of slicks we see offshore.  We start with slicks seen in the Mississippi Canyon area on July 31 and August 21. These would not be complete without a video of that chronic nightmarish oil leak known as "Taylor Energy" within about 10 miles of the tip of Louisiana, created by Hurricane Ivan's destruction in 2004 of a platform and over 20 pipelines in the vicinity and a resulting underwater mudslide. This leak cannot be stopped even to this day:

Here are photos and video of some of the surface oil slicks and sheens we saw in the Ewing Bank area on July 19 and August 20:

Coastal Areas and Wetlands
A welcome tonic to the discomfort we feel at the sight of the surface oil pollution, we never tire of the awesome Louisiana coastline and wetlands:


While we bemoan the thunderstorms and rainy weather for interfering with our finding wildlife, they are also an awe-inspiring sight to behold, over the water and the wetlands:


Mississippi River and New Orleans
The mighty Mississipi and New Orleans never fail to beg for more photos and video:

The Crew!
Last but not least, one of our intrepid crew decided it was time for some comic relief, and he (Don) managed to sneak in some video of the crew -- on this day that was Jennifer, Terese, Don, and Bonny (pilot).
