Rehabilitated turtles swim free
Just after 9am on Tuesday 29 November, two boats filled with Earthwatch volunteers from Amcor and scientist Dr Kathy Townsend headed out to deep water off North Stradbroke Island to release four healthy, rehabilitated turtles back into the open ocean.The loggerhead and three green turtles were all found back in August 2011 and were experiencing a range of issues, causing them to lose weight and be in very poor condition. Some of the turtles were found floating and were unable to dive for food which is often associated with marine rubbish inside the turtles gut, which is the current focus of the Turtles in Trouble research project. The biggest turtle – the Loggerhead known as Blossom – was rescued by the School of Biological Sciences undergraduate students on a field trip back in 2005. The turtle was found floating just in front of the research station during the field course and was carried back to the station for care by four students.
