Leatherback turtle swims from Indonesia to Oregon in epic journey

BANGKOK, Thailand – Scientists tracked a leatherback turtle that swam from Indonesia to the United States in an epic 20,000-kilometre journey as it searched for food – research they hope will boost international efforts to save the endangered species.

Leatherbacks, which can grow up to 2.75 metres in length, have roamed the oceans for 100 million years. But researchers at the U.S. National Marine Fisheries Service in California say commercial fishing makes the oceans too dangerous for the globe-trotting sea turtles, which face extinction if no action is taken.

“Migrations of this magnitude expose animals to a multitude of risks from fisheries on the high seas,” Scott Benson and Peter Dutton, scientists with the service, co-wrote in a paper that appeared last month in the peer-reviewed Chelonian Conservation and Biology.

“Effective conservation requires a better understanding of migratory routes and destinations to understand and mitigate the risks at sea,” they wrote.

The leatherback is the world’s most endangered sea turtle. In a telephone interview Friday, Benson estimated fewer than 5,000 adult females now live in the Pacific region. Males cannot be easily counted because they don’t come ashore. Conservationists estimate the breed could become extinct within 30 years.

Turtles “face a myriad of risks from things like ingesting debris like plastic, to travelling through areas that are used by multinational fisheries – fisheries that would catch (the turtles) in the course of trying to catch fish,” Benson said.

Benson and Dutton went to Indonesia in 2001 hoping to track some turtles using satellite transmitters, confirm their transpacific route and prompt action to prevent their extinction. Their research showed the animals ranged from the South China Sea to the Sea of Japan to the North Pacific.

One adult female began her journey in 2003 on a nesting beach in Jamursbamedi in Papua province, Benson said. He and Dutton tracked the leatherback and her hunt for food for 647 days until the transmitter’s battery ran out just off Hawaii. During her travels she swam as far as the state of Oregon.

“It’s the old adage of not putting all your eggs in one basket,” Benson said.

“If a foraging ground was bad one year, maybe another foraging ground would be good. Some portion of the population would always be able to find food.”

Peter Pritchard, a turtle expert and director of the Chelonian Research Institute in Florida, said he wasn’t surprised to learn how far the turtle travelled.

“It’s possible and only limited by the geography of the world,” Pritchard said Friday.

“They are masters of the ocean. There is a tremendous amount of muscle in the front.”

“This is a powerful fishing machine and remarkable diving machine.”

Benson called for action to protect leatherback turtles as they roam the seas.

“It will be the responsibility of many countries to ensure the species survives in the Pacific Ocean for future generations,” he said.

“It’s an animal that doesn’t recognize international boundaries. You can protect the nesting beaches but if you can’t protect the animal in the water, you haven’t done anything.”

This Blog has gone through many obstacles and attacks from violent Free West Papua separatist supporters and ultra nationalist Indonesian since 2007. However, it has remained throughout a time devouring thoughts of how to bring peace to Papua and West Papua provinces of Indonesia.
