They also found 23 reports of entangled turtles in peer-reviewed publications, magazines, newspapers and reports.
84 per cent of the 106 experts surveyed, said they had found turtles tangled in rubbish, in the Atlantic, Pacific Caribbean, Mediterranean and Indian ocean coast.
Although they found more than 1,000 entangled turtles, they believe the real number is far higher because many animals will decay at sea.
Greenpeace UK’s head of oceans Will McCallum said: « Nearly all species of turtle are endangered and yet research like this shows that the threats from human activity are only getting worse.
« The throwaway plastic we use for just minutes can turn into a floating trap for marine creatures like whales and turtles that lurks in our oceans for centuries.
« If UK ministers are truly feeling inspired after watching Blue Planet II, then a good place to start would be stopping plastics getting into the ocean by pushing ahead with plans for a deposit return scheme. »
The research was published in the journal Endangered Species Research.
