Will Sea Turtles Be The Big Victims of the Gulf Oil Spill?

The sea turtles in the Gulf of Mexico may turn out to be the ones in the most trouble from the Deepwater Horizon oil spill. Even though they haven't shown signs of oil, they may be ingesting it.

Dr. Mike Ziccardi, a veterinarian who runs the Oiled Wildlife Care Network and is handling all the non-bird oiled wildlife in the gulf, now says they're getting a high number of dead turtles, 156 so far. Mostly juveniles and mostly the rarest kind, Kemp's Ridley, TampaBay.com reports. The dead sea turtles "are in higher numbers than you would expect," he told Reuters.

No one is sure what killed the turtles. There was Dr. Ziccardi was initially very cautious, noting that turtles just wash up dead this time of year and that they showed no oil. Some blamed shrimpers. OnEarth, the NRDC blog, says that Sea Turtle Restoration Project (STRP) estimates fishermen kill 25,000 sea turtles each year.  And that's way down from a decade ago, before the mandated Turtle Exclusion Device, when 86,000 were wiped out.

Now Dr. Ziccardi he's contemplating something more insidious: that they are injesting the oil but it doesn't show up on the outside. "Marine mammals and sea turtles are much more likely to have less apparent external exposure and greater internal exposure than avian species," he wrote on his blog. Animals that don't show oil can have internal oil damage. Sometimes you can see it in their feces but others have "sub-apparent internal exposure." You can find that by looking for microscopic toxin damage or chemical analysis, he says.

Kemp's Ridley's are critically endangered and only found in the gulf and on the east coast. They're carnivorous bottom-feeders, exactly what you don't want to be in this oil spill. It's the smallest sea turtle, nests during the day and en masse at sites called arribadas. In 1947 42,000 nested in one day near Rancho Nuevo, Mexico. That fell to 5,00, but has climbed up to 7,866 in 2006. They nest at Padre Island, TX, too, but only 127 nests were counted in 2007.

A big set back was a 1979 oil spill in the Gulf of Mexico, the Ixtoc I,  that's a lot like Deepwater Horizon. the Blow Out Preventer failed. The spill was slow moving. Relatively few dead animals were found. Though the direct link was never found, the Times says, the population went way down.

All seven species of sea turtle are either endangered or threatened and five live in the Gulf of Mexico, the Parks Service says. The other big threat to sea turtles is people stealing the eggs and eating the females when they go ashore to lay them. It's mostly outlawed, but just this week Mexican cops caught two guys with 5,800 eggs near Acapulco.  In Denespar, Indonesia, cops confiscated 71 huge, endangered green sea turtles about to be served as food in a stall, the AP reports. The Jakarta Post says they also just caught men smuggling 12,000 turtle eggs in cigarette cartons aboard a ferry.

Looks like we might not have oiled birds being soaped up for camera, but something much slower and grimmer.

Your Hair Probably Isn't Going to Clean Up the Oil Spill--and Neither Is Your Dog's or Alpaca's

Hundreds of volunteers are assembling booms at Boom B Qs
Funny thing about all that hair and fur being shorn around the country to great fanfare to sop up the BP gulf oil spill: nobody wants it. Or at least the people actually cleaning up the oil say it isn't as good as the store-bought booms they're using. But that hasn't stopped people from sending it in and reporters from extensively covering the sweet but so far futile gesture.

Last week the official spill Facebook page, Deepwater Horizon Response,  put out this deeply unpopular message:
We are not using hair booms at this time but are using commercially available sorbent boom when possible. In a February 2010 NOAA field test, commercial sorbent boom absorbed more oil and much less water than hair boom. Widespread deployment of hair boom could exacerbate the debris problem. There is adequate supply of ...sorbent boom for now, but we do encourage ideas of alternative solutions by calling (281) 366-5511.
The main group amassing hair, Matter of Trust, does some amazing recycling and has been championing and testing hairmats since at least 2007. The hair, stuffed inside pantyhose, really seems to work. But even they say only the hazmat crews should install and remove the booms. They're taking the rejection graciously, but proceeding full steam ahead:
BP hasn't spent a lot of time thinking about the properties of hair, fur, wool and fleece. And they're a little busy right now.... Matter of Trust is saying officially: "At this time, we are simply providing volunteers the opportunity to make hair boom and stockpile them all along the Gulf Coast, in case BP needs them." We're calling it Plan H (H is for Hair).

But let none of that get in the way of a "local people helping in international crisis" story.

Even the Canadians and horses are getting in on it. Well after the word that booms aren't being used, alpacas are still getting shaved and National Geographic is still doing a story on it. The group collected 10,000 pounds of alpaca hair. Hair is coming from Soho, Petco, and fans of Rachel Maddow. The Miami Herald and  About.com are still pushing haircuts. ZooToo has a how-to story on donating your pet's hair. Some stories have a teeny disclaimer on the end--oh, yeah, this may not work or be used sort of thing.

All of this is a sweet gesture, like donating blood after a catastrophe. It's wonderful to see so many people worried about the turtles, pelicans, dolphins and manatees their hair might help. But is it doing any good?

The Price of All This Cleaning Up Oiled Wildlife?

BP sign from alvez modified by animaltourism.com
Wildlife rescuers in the gulf are getting so few oiled animals they're starting to worry that the cost per animal seem ridiculous. After Exxon we had reports of "$80,000 otters." If you hear anything about a $300,000 sea gull, be skeptical.

Mike Ziccardi, a veterinarian who runs Oiled Wildlife Care Network, has been offering the most candid and complete news on the wildlife situation on their blog.  He's been bracing for both an onslaught of injured animals and a backlash against the cost of saving them. "This response is likely to be very costly when it is all said and done – especially if compared on a “per-bird” or “per-turtle/mammal” basis (or at least I hope it is, as that will imply low animal numbers)," he writes today.

In Valdez less than 5% of costs went to wildlife care, Ziccardi says. Caring for oiled wildlife is always done on the cheap, staffed by volunteers, who often sleep in their cars. And lord knows you've already heard about Dawn donating its useful soap.


In 1992 James Estes first criticized oiled wildlife rehabilitation efforts as showy and ineffective, pricing the surviving otters at $80,000 each from a total $18 million otter effort. (I'd say that you have to count the dead ones, too--even though that only brings it down to $14,500.) Later he asked "why rehabilitate oiled wildlife"? So you don't hate him, know that Estes, an adjunct professor at UC-Santa Cruz, isn't saying screw you, sea otters. He's saying the money could be better spent trying to prevent spills and shore up vulnerable populations.

In 1999 Dr. David Jessup and Dr. Jonna Mazet argued at the International Oil Spill Conference that the $80,000 figure was wildly inflated and took into account building several extremely remote care facilities from scratch. "The actual cost of collecting and caring for oiled sea otters is about $4,000 to $5,000 and marine birds about $600 to $750 [bargain!]--about one-twentieth the cost often cited from the Exxon Valdez experience," they write.

Replacement cost is another way to value animals (and other kinds of intangible losses). Luckily, the gulf doesn't have those expensive sea otters. But it does have some endangered sea turtles that should be nesting soon and manatees. People would pay a pretty penny for any of those.

But why bother saving them? Because it's the right thing to do. The question itself seems based in the reactionary view that only ecosystems and the environment matter and that it is somehow childish to value the life of an individual animal. Too many people are so afraid of being called anthropomorphic that they rush to something I would call tree-pomorphic, the assumption that other animals have no value beyond their physical properties and contribution to the environment.

Where Are All Those Oil-Soaked Birds We Were Expecting?

One peculiar thing about the Deepwater Horizon oil spill so far: hardly any wildlife covered in oil. The lack of  oiled birds has mystified rescuers and exasperated the media. TV networks are clamoring for images, showing clip files and giving the impression that tons of animals are showing up hurt. That's not so--at least not yet.

Mike Ziccardi, a vet and director of the Oiled Wildlife Care Network,  says on the OWCN blog that he got into a spat with "a fairly irate reporter from a major national news outlet" who demanded video access to the necropsy (animal autopsy) of some sea turtles. The network were desperate for dead turtle images even though the turtles didn't show initial signs of oiling and, as Ziccardi pointed out, were in found in a time and place typical of stranded turtles. (The other big threat to turtles is shrimp boats, Wallace Nichols from Grupo Tortuguero points out.)

Keith Olbmermann started a broadcast this week in ominous tone about "as dead jellyfish begin to wash up on the Mississippi coast." Dead jellyfish might be the one bright spot of the oil spill, given that the Gulf Dead Zone has caused a plague of jellyfish in the gulf.

Apparently California Gov. Arnold Schwarzenegger so expected oiled wildlife images that he dreamed some up. He just announced that he was withdrawing support for drilling off California's shores: "I see on TV, the birds drenched in oil, the fishermen out of work, the massive oil spill, oil slick destroying our precious ecosystem," he said at a press conference.


Both Schwartzenegger's descion and the lack of injured animals is fantastic, of course. Right now, nearly two weeks into what may be the worst oil spill in U.S. history, exactly two birds are in treatment. There's a northern gannet and this brown pelican. They're going to be media stars, these two.

Ziccardi is mystified by the lack of oiled animals. By this time in an oil spill, he says, "wildlife field operations are in full swing, the largest number of animals are being (or have been) collected, and facilities are bustling with activity." He doesn't know what to make of this lack of animal injury: "Normally I would be overjoyed at this lack of overt animal impact. No, overjoyed is a significant understatement ... but is this lull what we should expect in the days to come, or is the Sword of Damocles really about to come crashing down?"

That's a question all of us are asking. We've been told that the oil spill was on the verge of hitting the shore since last Friday morning. I'm thrilled it hasn't fouled beaches, wetlands and wildlife, but how is it not? Where is the oil going?

Ziccardi wonders if the oil dispersant chemicals are keeping the oil from the surface--where it would do the most damage to birds and marine mammals--but leaving it in the water where it will do long-term, hidden damage. Especially to clam beds. He uses my favorite word of the oil spill: BIOMAGNIFY. That means basically get eaten by the bottom of the food chain, concentrate there, then work their way up the food chain.  Kind of like mercury.

Wildlife Rescuers in Gulf Overwhelmed--By Volunteers, Not Patients

San Francisco Oil Spill - Partially Oiled Gull
Oiled gull in CA in 2007 by Ingrid Taylar. Not many oiled birds seen yet in the gulf.
So far only a single bird, a Northern Gannett, has shown up oiled from the massive Deepwater Horizon spill. Wildlife rescuers and nonetheless overwhelmed--by all the untrained human volunteers.

As the potential for the spill gets bigger, the big wildlife groups are contemplating holding training classes to equip the would-be volunteers, says Kai Williams, executive director of the International Wildlife Rehabilitation Council.


Right now several groups are taking in information from potential volunteers.  The National Wildlife Federation is directing people to sign up with the Coalition to Restore Coastal Louisiana.

 "If you have the ability to restain an animal, that's going to be huge, just the basic ability to hold an animal," says Williams. "They're getting a lot of untrained people, not wildlife rehabilitators, people who have never picked up a bird."

What makes planning the response so hard is no one knows how big this still-developing catastrophe is going to be or when and where a rush of injured animals will show up. Some contemplate that the Gulf Stream could wrap it around Florida. Some worry the spill could end up bigger than Valdez. Williams notes that fewer birds live in Valdez, but there are also turtles and marine mammals to worry about.

The northern gannet is being bathed, fed electrolytes and pepto bismal, but rough weather this weekend prevented picking up more patients. A caretaker told the AP that the bird came in brown, but should be white at its current age.


Nationally, three groups are known for their training in helping animals that have gotten coated in oil.

How Will the Gulf's Dead Zone Impact the Oil Spill?

The Deepwater Horizon spill in the Gulf of Mexico may collide with an area already bedeviled by environmental catastrophe, the infamous Dead Zone--an area of essentially no life or oxygen. So what happens when an inexorable oil slick meets and an undead patch of water?

The Gulf's Dead Zone is about 6,000 to 7,000 square miles, one of the biggest in the world, Microbial Life Educational Resources of Carleton College says. It's caused by fertilizer run-off in the Mississippi overfeeding algae. Phytoplankton gobble up the algae--and all the oxygen. Scientists call the areas hypoxia--or low oxygen. They can't support life.

The oil spill so far is smaller, about 1,800 square miles. So far.

Right now the dead zone is west of the Mississippi and the oil spill is east of it. The dead zone is mainly at the bottom, which is littered with phytoplankton carcasses. The oil is on top.

But Nancy N. Rabalais, Ph.D., executive director of Louisiana Universities Marine Consortium thinks they're likely to meet.

"If the winds continue from the southeast as is common this time of year, then the surface manifestation may move to the west of the Mississippi River delta and become a surface feature of the Louisiana area of hypoxia," says

Some seem to have fantasized that the oil burn off will end up cleaning up the dead zone. Not so, says Rabalais. "The burn would reduce the more volatile and toxic components," [in the oil] she says, but not burn off the algae.

The algae isn't going to slow the oil down, she says, but the oil may slow down the production of algae:

"The movement of the oil would not be affected by where the area of low oxygen may be. Algal production if the oil were to come into the low oxygen would probably be reduced in productivity because of the proximity of the oil."


The dead zone won't necessarily have cleared out the wildlife; it's too soon to tell, she says. While the dead zone is indeed dead to most sea life like plants and fish, birds and marine mammals pass through: "The area of low oxygen does not affect birds and marine mammals because they are air breathers and the marine mammals and turtles can reach the surface of the water for atmospheric air."

The impact she expects is the oil will calm that waters of the dead zone. There will be less oxygen transfer from surface air into surface waters. The waters will stratify. The oil would cut back on the production of phytoplankton at the surface. And the oil and dead zone could pinch in on organisms caught between the top and bottom.


Perhaps the biggest impact is that the oil spill may decimate the wetlands--the wetlands the government had been building up in hopes of filtering water of fertilizers to short-circuit the dead zone. So much for that.

Several Manatees Swimming Toward Danger and the Oil Spill; Mobile May Release Dammed Waters

Biologists know that a handful of manatees are in the Gulf of Mexico and swimming westward--toward the massive Deepwater Horizon oil spill, but so far they have decided not to try to intervene. Mobile Bay officials may release dammed waters to push the oil away from the bay, a local scientist says.

A female manatee that spends the summer in Mobile Bay is now in Appalachicola Bay, FL, says Ruth H. Carmichael, senior marine scientist at the Dauphin Island Sea Lab, which is bracing for the oil slick.  Appalachicola Bay is roughly 250 miles from Mobile--if you take the shore route. They can swim up to 45 miles a day, but 5-15 is more likely.

"I hope she finds a nice location to wait for a while," Carmichael says. "The USGS also has a few tagged manatees they know are moving this way.  We are doing nothing to move or disturb the animals.  Right now the oil is offshore and the manatees are in shore.  We need to trust them to take care of themselves for now."

Manatees spend the winter near hot springs or power plants in Florida, but as their population has recovered, they are swimming further in the summer. A few now regularly visit Alabama and every few years a young male makes it up to New England.  

"Mobile Bay is trying to arrange for discharge of dammed waters , if needed, to force water out of the Bay and keep it westward off shore," Carmichael says. "Mississippi may be in greater danger.. but it is difficult to predict what will happen.  This is a terrible event. Discovering a third leak was tragic."

Pelicans, Otters, Manatees Could be Hurt by Deepwater Horizon Oil Spill

Deepwater Horizon oil spill seen from space over LA

Endangered sea turtles, herons, white and brown pelicans, dolphins, whales, manatees, tuna and assorted sea birds  could all be hurt by the Gulf of Mexico oil spill that is now 16 miles off the tip of Louisiana and alarming wildlife officials all the way to Florida.

The Coast Guard is burning the oil, hoping that will keep it from making landfall and destroying wetlands. I wonder if, ironically, the giant dead zone in the gulf may mean that the area the oil spill hits may be devoid of life anyway. The next step for wildlife rescuers would be to herd animals out of the area by hazing them.
 
The International Bird Rescue Research Center in Texas says they've been put on alert for the decapitated oil well, which is gushing about 1,000 barrels (42,000 US gallons) of crude daily and already can be seen from space, with a circumference of 600 miles.
If the spill stays offshore then the impact will likely be minimal to birds. Coastal birds that are highly at risk if the spill hits shore are brown and white pelicans, terns, gulls, shorebirds, skimmers and herons. Nesting and feeding areas for birds and sea turtles such as marshes and beaches could be impacted.
Loggerhead and Kemp's Ridley turtles are in the area, Live Science says. Birds are vulnerable if they ingest the oil or get coated in it. The oil removes their waterproofing, then they die of cold. In a report on dealing with oil spills, the EPA says mammals that groom themselves with their mouths, like otters, end up eating oil and getting it in their eyes. Sea otters don't live there; river otters do. No one really knows how to help marine mammals stuck in oil, they say.
Procedures for capturing, treating, and releasing animals may hurt them more than the oil does. For example, manatees are particularly susceptible to secondary fungal and bacterial infections following capture or transportation. 
Whales, dolphins, seals and manatees end up breathing hydrocarbon vapors that hurt their lungs, getting it in their eyes and nursing young eat it. Manatees summer as far west as Texas (but that's rare); a few regularly visit Mobile, AL. The biggest danger to manatees, which spend the summer as far west as Texas, may be getting hit by boats responding to the disaster.

So far the Tampa Tribune reports that the Florida Fish and Wildlife Conservation Commission hasn't found any oiled birds, but they are doing necropsies (animal autopsies) on 15 migratory birds found dead Tuesday in the Pass-a-Grille area of St. Pete Beach.


In Alabama, the Dauphin Island Sea Lab is sending boats out to test the waters and "trying to re-establish oiled bird emergency response plans that have not been exercised for many years." They fear it could be the worst Gulf oil spill ever. Coast Guard Rear Adm. Mary Landry goes even further: "If we don't secure this well, this could be one of the most significant oil spills in U.S. history."

Santa Monica Sushi Restaurant Serves Whale, Makers of The Cove Document on Way to Pick Up An Oscar

The people who made The Cove, the documentary about Japanese Dolphin slaughter that won an Academy Award Sunday, used some of the same techniques to bust a hipster Santa Monica sushi restaurant for selling whale, the New York Times reports. DNA tests confirmed that a $60 piece of sushi that The Hump sold as whale was in fact the endangered Sei Whale (Balaenoptera borealis). that $60 piece of sushi was sei whale.

DNA-testing sushi is now becoming a food investigation mainstay; it's almost as popular and fun as finding e. coli at food carts. But normally the results are the opposite: the fish is not what the restaurant says. It's a cheap substitute. In this case it was on the Omakase, or tasting menu, and the wait staff told the undercover diners they were eating whale, sometimes calling it by its Japanese name, kujira.

The food blog Shizuokasushi explains how whale is served casually in Japan, though usually sperm whales. Japan hunts about 100 sei whales a year under the guise of "research," according to the IUCN Red List.

Louie Psihoyos, photographer and director of The Cove, worked with “director of clandestine operations” Charles Hambleton, who made tiny cameras for diners to wear--once for themselves and a second time for investigators. An affadavit from investigators describes a search of the restaurant and suggests the whale may have arrived via a Mercedes parked out back.

It won't be as exciting as The Cove, but I sure hope they make video of the sting.

Jaguars, Extinct in US, Found Within 30 Miles of Border

A jaguar has been confirmed living--or at least roaming--within 30 miles of the U.S. border with Mexico. The Cougar Network, which tracks big cat sightings, sent out word that the Sky Island Alliance has two photos of jaguars eight days apart about 90 miles north of where everyone thought they lived in Sonora.

Conservation groups like the Northern Jaguar Project,  have worked for years to bring back the big, spotted cat that once ranged as far north as the Grand Canyon across California, Arizona, New Mexico, Texas, and possibly Louisiana.

The find would be significant because last year the last known U.S. jaguar died under circumstances that increasingly look dodgy. Arizona Fish and Game caught Macho B in a trap they said was for bears or cougars. They tranquilized and collared him. Days later the then-sluggish cat was euthanized. The capture and drugs may have hastened his death. Just last month investigators found that the capture was intentional, a possible felony since the jaguar (Panthera onca) is endangered.

Just last month the Fish and Wildlife service reversed a 2006 decision and determined that the jaguar deserves a critical habitat. Even the known population in the Northern Jaguar Preserve, 135 miles south of the border, is cut off by hundreds of miles from the the main population.

The motion-activated game cameras showed the jaguars from different sides, so no one is sure if it's the same cat, Sergio Avila, an alliance biologist in Tucson, told the Arizona Daily Star. A handful of jaguars have been spotted just over the U.S. border in recent decades. Where the sex was determined, it was always males, probably pioneering out to find new territories.


Carlos Elias, co-owner of El Aribabi ranch where the photos were taken, his wife and biologist Avila exploded with joy when they reviewed the pictures and found the jaguar. They "began hugging and cheering - a celebration of three years working together to preserve the excellent ecological conditions on the property so that species like the jaguar have a place to roam and thrive," the Sky Island Alliance reported.

"Our family has worked hard to restore ecological processes in this land," Elias said. "We hope this gets the attention of government agencies and foundations, so we can establish a sustainable model that protects biodiversity and supports landowners and their families at the same time."
