Zeeschildpadden liggen te rotten op stranden in Golf
Een jaar na de olieramp in de Golf van Mexico is in de regio een nieuw toeristisch seizoen begonnen. Strandgangers treffen er echter nog steeds de gevolgen aan van de milieuramp van vorig jaar. Zeeschildpadden blijven op de stranden aanspoelen en liggen te rotten in de lentezon.

Dode zeeschildpadden spoelen de laatste weken massaal aan op de stranden van Magnolia State. Samen met andere dode dieren liggen de schildpadden in het zand te rotten. Voor veel inwoners van de Golf-regio zijn het schokkende beelden. Ze hebben nog nooit een zeeschildpad van dichtbij gezien, noch levend noch dood. Laurel Lockamy trok er met haar fototoestel op uit.

Spoor van dode dieren
Op een wandeling langs de kustlijn komt Laurel heel wat dode dieren tegen. Eerst ziet ze een dood gordeldier dat in het zand ligt opgerold. Onderweg liggen er verschillende dode vogels. En dan merkt ze opnieuw een dode zeeschildpad op, die op de oever aan het ontbinden is. Aangezien schildpadden in de Golf een bedreigde diersoort zijn, belt Laurel een onderzoekscentrum dat belooft de schildpad te komen ophalen.

Een uur later komt een team ter plaatse. Ze maken foto's, meten de schildpad op en spuiten er oranje verf over. Daarna laten ze het stoffelijk overschot gewoon liggen. Een andere schildpad verderop gooien ze gewoon op het stort. Onderzoek naar de precieze doodsoorzaak doen ze al lang niet meer. "Ik ben tegenwoordig bang om naar het strand te gaan", zegt Laurel.

Wie ruimt de lijken op?
Nochtans zegt het NOAA dat alle dode schildpadden getest worden om na te gaan of ze stierven door bijvoorbeeld visnetten of door olie. Tot nu toe werden de resultaten van de recente sterfgevallen echter nog niet bekend gemaakt. Het is aan de lokale autoriteiten om de schildpadden op te ruimen. "Wij komen zo snel als we kunnen. We laten die schildpadden daar geen dagen liggen", luidt het.

"Ik ben het beu om mensen te vragen de schildpadden te komen weghalen", zegt Shirley, een grootmoeder die bezorgd is over haar kleinkinderen. "Ze liggen daar te rotten en er spuit vanalles uit. Wie gaat de kinderen die op strand spelen uit de buurt houden?"

Tientallen dode schildpadden
De voorbije maand zijn officieel meer dan 60 dode zeeschildpadden gevonden in Mississippi, Alabama en Louisiana. Het aantal aangespoelde karkassen is echter maar een fractie van de hoeveelheid schildpadden die gestorven zijn. De bevolking van de Golf is nog maar eens bezorgd, nadat ook dode babydolfijnen in olie gevonden werden. Het is duidelijk dat de grootste milieuramp in de geschiedenis van de VS nog hevig aan het nazinderen is. Reden tot optimisme is er een jaar na de ramp met het olieplatform Deepwater Horizon van BP nog lang niet... (gb)

Residents Say Sea Turtles Rot on Beaches of the Gulf
Laurel Lockamy thought she had seen the worst of the oil disaster last summer when waves of oil and tar patties washed onto her beach in Gulfport, MS, taking a major toll on the local tourist industry.

But now a new disaster is unfolding, she says, just as beachgoers are heading back to the water. A large spike in the number of dead sea turtles is being reported across the beaches of the Magnolia State. Residents now find them rotting in the springtime sun along with other animals and birds that float in with the tides.

Laurel has photographed three dead sea turtles on this stretch of sand in the past two weeks. Like other Mississippi residents, she’s never seen one dead—or alive—before.   

Earlier this week, Laurel went out to the Gulfport beach with her camera to see if any new turtles had washed in.  First she saw a dead armadillo curled up in the sand, along with several other dead birds. But a short stroll later she came across another turtle, decomposing along the water’s edge.

Laurel called the NOAA hotline and the state’s Institute of Marine Mammal Research (IMMR) to arrange a pickup. All turtles in the Gulf are on the endangered species list, and they are protected under federal law.

Over an hour later, she says, a crew from the IMMR showed up, took pictures and measurements, spray painted it with orange paint for pickup, and then left the turtle on the beach. A county beach worker told her they scooped up another turtle not far away and took it to the dump.

“They didn’t do any testing,” Laurel says, “they just measured it, sprayed it and left it on the beach to rot. This is ridiculous. Why isn’t anyone testing them? I’m terrified to go to the beach these days.”

NOAA Fisheries Service says its turtle stranding network collects all newly found or moderately decomposing turtles for testing to try to determine cause of death, include drowning from fishing nets, biotoxins and disease or complications from oil pollution.

Connie Barclay, a NOAA fisheries spokeswoman, said all turtles that are collected are tested, but so far no test results of the recent strandings have been made public. Local authorities are responsible for disposing of turtles that have already been counted and examined. “We get out there as quickly as we can,” she said. “We don’t just leave them there for days and days.” she said.

But according to some Gulf residents, that’s exactly what’s happened in some cases. Pass Christian resident Shirley Tillman has witnessed 13 dead sea turtles washing up on beaches near her home, nearly all in the past few weeks. Earlier this week she found four on one day. She says in several cases she’s called the IMMR and NOAA authorities and given them coordinates to have the turtles picked up, only to go back and find they haven’t been picked up for days.

“I’m getting tired of going out there and trying to get people to pick them up,” says Shirley, a grandmother and wife of a Pass Christian home builder. “These turtles just lay there decomposing and the stuff just explodes and stuff oozes out of them. Who’s going to keep the kids from coming over and play in the sand right next to them?”

NOAA says they’ve found more than 60 dead sea turtles in Mississippi, Alabama and Louisiana through April 3 of this year, nearly all of them in the past month. [NOAA updated numbers as of later today are now nearly 100 stranded turtles this year, 87 since mid-March]. Even though turtle strandings tend to spike in the spring, this is a high number of turtles to strand in these areas. NOAA records show most are found along the gulf coast of Florida and Texas. Experts say the number of turtles carcasses recovered represents a small fraction to the toal number that have died.

IMMR, which collects endangered turtles and federally protected dolphins stranded in Mississippi and Alabama, says its crews go out and bring the turtles back for necropsies, which are handled by the federal government. “We’ve been crazy busy,” says Shannon Huyser, a stranding coordinator. “But we usually get there the same day we get the calls. If they’re not too decomposed, we bring them back for necropsies. But that’s pretty rare.”

But some residents think more needs to be done. They wonder why it sometimes takes so long for these turtles to be picked up and tested. They worry that the spike in turtle deaths, like the dead baby dolphins washing in, shows something isn’t right with the Gulf after the worst oil spill in US history.

But most of all, they are praying these lifeless ancient animals of the sea aren’t a sign of worse things to come.

Gulf of Mexico Oil Spill: Turtles Dying, but Not From Oil
Dead Sea Turtles Did Not Have Oil in Their Bodies; Shrimpers' Nets Suspected
Workers in the Gulf of Mexico, struggling to bring the massive BP oil spill under control, found themselves with yet another issue to deal with: What is killing the sea turtles in the spill zone?
It's not the spilled oil, said officials. At least 35 dead turtles have been found washed up on shore, an unusual number. But necropsies found they were clean of the toxic brown crude that has been spewing from the floor of the Gulf since April 20, when the Deepwater Horizon drilling rig exploded and burned, 50 miles off the Louisiana coast. Eleven oil workers were presumed killed, and an estimated 5,000 barrels of oil per day have been leaking from the wrecked wellhead since.

"We are seeing turtles and marine mammals, including dolphins and whales, in and outside the oil," said Sheryan Epperly of the National Marine Fisheries Service, which has been surveying the area by helicopter.

So why are they washing up on shore dead? Federal fisheries officials said they are investigating whether shrimpers, heading out early as part of an emergency shrimping season, are to blame.

Epperly said investigators are looking into whether shrimpers are removing "Turtle Excluder Devices" -- TEDs for short -- from the trawling nets they lower into the water to catch shrimp. A TED is a kind of grid that filters turtles from the smaller shimp gathered up by a net, allowing the turtles to escape.
Shrimpers in the Gulf are required to have TEDs in their nets, but some shrimp escape through them, and investigators say anxious shrimpers may be trying to catch all they can before more fishing areas are declared off limits because of the oil spill.

Louie Miller of the Sierra Club had his doubts: "I discount that theory heavily. I think shrimpers are in enough trouble as it is. I point the finger at BP at this point until they are proven innocent."

Miller was suspicious of the chemical dispersants being used to break up the slick.

"What concerns us is that there's a lot of talk from BP that these chemicals are under proprietary protection, so therefore we can't get the information," he said. "That's totally unacceptable to this situation."
Most of the turtles found so far are Kemp's Ridleys, which are an endangered species. The only place in the world where Kemp's Ridley turtles nest is the western Gulf of Mexico. They are currently in peak nesting season, and their foraging grounds are located in the spill area.

Heavy Artillery
Cleanup crews have used any techniques they could to corral the leaking oil. Floating booms are deployed to surround the slick, which mostly floats on the surface, but they are ineffective in rough seas. Controlled burns of some floating oil resumed this week.

BP has been pinning hopes on a large metal "dome" -- actually box-shaped -- to be lowered over the wellhead to trap the leaking oil so that it can be pumped to the surface and collected by a drill ship.

Even hair, donated by barber shops and salons and stuffed in panty hose, has turned out to be useful for sopping up oil.
Gulf Oil Spill: Protecting Wildlife
Chemical dispersants, pumped into the water or sprayed on the surface of the Gulf slick, have been used to break up the oil. But late Wednesday BP said it would stop using dispersants underwater until tests can be done to make sure there are no major environmental consequences.
Dispersants have been used for years, but BP took the unprecedented step of pumping them directly down to the vicinity of the leaking wellhead, 5,000 feet below the surface of the water.

"When the dispersant and the oil mix, it just breaks the oil into smaller molecules, and the oil just breaks into smaller droplets," said Bob Fryar, a senior executive of BP. "At that time the ocean just takes over and it just degrades naturally."

Fryar, at BP in Houston, played down the risks, saying oil leaks into the Gulf of Mexico all the time.

"You know, actually, you typically have small oil seeps that come up from the ground already," he said. "There's probably one to two thousand barrels a day oil seep that's taking place in various places, and the earth just naturally takes care of that."

Biologists have been worried about other wildlife -- birds, fish and dolphins -- that could be in danger if the winds change and the oil spreads beyond the current slick area near the mouth of the Mississippi River.
Oil breaks down many animals' natural protection. A bird's feathers are naturally coated as insulation against the elements; a dolphin's eyes have an outer layer that shields them from toxins.

"An animal out there doesn't know that this is crude oil and it's toxic," said Moby Solangi, president of the Institute for Marine Mammal Studies in Gulfport, Miss. "All it knows is that this is something to play with."

Ayana Harry reported from Gulfport, Mississippi and Ned Potter wrote from New York. Additional reporting by Clayton Sandell in Houston.
