Greenpeace is on an expedition in the Sargasso Sea, a unique region in the North Atlantic Ocean that is home to a diverse array of marine life, including loggerhead and green sea turtles.
The journey, part of the "Protect the Oceans" year long tour, will see Greenpeace and University of Florida researchers team up to study the impact of plastics and microplastics on marine life and the importance that the Sargasso's drifting Sargassum seaweed habitat has for the development of juvenile sea turtles.
