Volunteers Help Baby Sea Turtles Survive the BP Oil Spill

The life of a sea turtle hatchling isn’t easy. After they hatch out of leathery eggs in a nest, buried deep in the sand, they move immediately toward the light above the ocean, scramble into the surf, and swim for a couple of days straight without stopping. Finally they rest in floating seaweed called sargassum. Sea turtle babies float along in the sargassum, a mini-ecosystem that provides food and protection, for a few years until they grow from about the size of a cookie to the size of a dinner plate.

This year, however, wasn’t a normal year for the sea turtle hatchlings. Because of the 4.9 millions of barrels of oil spewed into the Gulf as a result of the BP oil spill, the largest accidental marine oil spill in the history of the petroleum industry, those seaweed life rafts were covered in oil or were incinerated during the many controlled burns. Under these conditions, most of these sea turtle hatchlings wouldn’t have survived. Wildlife officials decided to intervene and transport the latest generation of sea turtle babies to a cleaner part of the ocean.

On October 1, the New York Times ran an article, The BP-Spill Baby-Turtle Brigade by Jon Mooallem that tells the inspiring, though bittersweet, story of the extraordinary efforts of the volunteers who helped save the hatchlings. For years, volunteers with the Alabama organization, Share the Beach, have taken time out of their lives each year to help protect threatened and endangered sea turtles along the Alabama coast. During the nesting season, they clear the beach of debris so turtles can lay their eggs; they patrol the beaches and protect the nests after the female turtle lays her eggs; and they give the hatchlings a head start by helping them reach the ocean.

Because of their experience , the U.S. Fish and Wildlife Service asked these volunteers to help dig up the nests during the last days of the eggs’ incubation. They then packed the eggs in Styrofoam containers, and the eggs were transported by FedEx trucks to a climate-controlled warehouse at the Kennedy Space Center on the east coast of Florida.  After hatching, the baby turtles were released into the oil-free Atlantic.

But it wasn’t easy for the volunteers to let their babies go. As quoted in the NY Times article, a Share the Beach team leader named Bill Hanks said, “It’s kind of like it’s our turtles. You get attached to them, almost like a mama-daddy thing.”

Sending the eggs was especially difficult because a mature female sea turtle will usually return to the beach where she hatched to lay her own eggs.  Because sea turtles’ nesting and hatching was disrupted and they entered the ocean from another beach, the question is, will these turtles eventually return to Gulf Coast beaches or to Florida beaches?

But the volunteers, though devastated, knew they had to do it for the sake of the turtles. (Incidentally not all scientists are in favor of this type of hands-on intervention with sea turtles, but most seemed to agree it was acceptable in such an extraordinary crisis.)

In late August the operation wound down as the sargassum seemed to recover. Although the surface of the Gulf appears to be oil-free, it remains to be seen what has happened to all that oil and chemical dispersant. Those sea turtles that depend on food deeper down in the ocean may suffer. For example, the main diet of leatherback turtles is jellyfish. Have jellyfish absorbed oil and disperant chemicals, and thus will now be ingested by the critically endangered leatherbacks? It seems likely.

While things look bleak for leatherbacks and other marine animals in the Gulf, at least some of the sea turtle babies are off to a good start thanks to efforts of the U.S. Fish and Wildlife service and the Share the Beach volunteers.

Sea Turtle Hatchlings Released in Gulf of Mexico

At  Padre Island National Seashore, thousands of Kemp’s Ridley sea turtle hatchlings, raised in captivity, have been released today, but they face an uncertain future. These hatchlings will imprint on the sand at the Padre Seashore. If they survive, female adult sea turtles will return in several years to the same area to lay their own eggs.

The sea turtle hatchlings will face many natural hazards: predation by shore birds, crabs, fish, or other animals.  In the first few days in the ocean, the baby sea turtles swim for more than a day without stopping—a pretty amazing feat for a newly hatched reptile that could fit in the palm of your hand. After this swimming frenzy, they rest and feed in patches of seaweed.

But these hatchlings also face an unnatural hazard:  a habitat fouled with oil. Unlike most sea turtles that roam far, sometimes thousands of miles, Kemp’s Ridleys stay close to home, preferring the warm waters of the Gulf of Mexico. According to Juan Rodriguez, chief of interpretation and education at Padre Island,  as quoted in a USA Today article, adult females are most at risk because their favorite places to eat are in the coastal marshes of Louisiana, where the oil first hit land.

Not everyone thinks releasing the hatchlings is a good idea. Todd Steiner, director of the Sea Turtle Restoration Project, which works to protect sea turtles, opposes the release because the turtles will float in currents that may lead into oil-polluted areas. “We believe they’re going to get into the oil and die,” Steiner said.

Yet others like David Godfrey, executive director of the Sea Turtle Conservancy in Gainesville, Florida, argue that keeping the turtles too long in captivity may disrupt their navigational and foraging skills. He is in favor of releasing the Kemp’s Ridleys as long as Texas is oil-free: “Everybody who is critical of that decision has a right to be critical because it’s not a black or white decision. If oil comes into Texas with a hurricane, nobody knows what would happen. Is it absolutely foolproof, 100%, signed, sealed, delivered? I don’t know. Nobody knows.”

Gulf Coast Wetlands Threatened by Oil Spill

We’ve abandoned our amphibian friends for a couple of weeks to write about the Gulf Coast Oil spill, and while I’d hoped to get back to them this week, the latest news about the oil washing up and covering wetlands seemed too important for us to ignore. And it is an issue that relates to amphibians. While few amphibians live in salt-water wetlands, fresh-water wetlands are vitally important to them.

Wetlands are some of the most environmentally productive ecosystems on earth. Some common names for wetlands are marsh, swamp, or bog. To be called a wetland, an area must be soaked with water for part of the year. Louisiana’s wetlands wind through shallow estuaries, inlets, bays, and reefs. So what’s the big deal about these wetlands?

  • Wetlands provide a habitat for a large variety of wildlife and plants
  • Wetlands are a nursery area for fish, shrimps, crabs, oysters and other wildlife—a calm area protected by heavy waves.
  • Wetlands are like a kidney for other ecosystems, filtering out, cleaning, and storing water.
  • Migratory birds nest in the wetlands

What Oil Does to Wetlands

The glue that holds the marsh together is grass. If grasses are repeatedly covered with oil, they will suffocate. It may take years for intertidal salt marshes and sea grass beds to recover from this kind of oiling.

As quoted by Irving Mendelssohn, a Louisiana State University botanist who specializes in wetland plants, in an AOL News article, “Once they’re dead, the soil collapses,” he said. “Then the soil becomes flooded and can’t grow back. The low areas that become ponds, the ponds form lakes and then the wetland disappears.”

How can the marshes be saved? Some suggestions include burning the oil-covered plants, low-pressure flushing, which helps push oil into areas where it can be vacuumed up or absorbed, cutting back vegetation to leave plants intact, and adding nutrients to help speed to degradation of the oil. Louisiana Governor Bobby Jindal has suggested dredging sand from the Gulf of Mexico and building islands to stop the oil from reaching wetlands. None of these methods is considered ideal and all have potentially serious environmental repercussions.

Even if people don’t care about wildlife and biodiversity, they should be concerned about the destruction of the wetlands. Almost all of the sea life that we consume from the Gulf of Mexico begins its life in these sea grass beds and wetlands. Also, the wetlands provide a buffer for storms and hurricanes, absorbing wind and tidal forces—of vital importance in this hurricane-prone area.
