April 25, 2019 — Sea turtle populations in Pacific coral reefs are increasing, according to a study that reveals the positive results of environmental protection efforts around the world and gives researchers information to protect these turtles from the effects of global changes.
Researchers from the U.S. National Oceanic and Atmospheric Administration’s Pacific Islands Fisheries Science Center recorded numbers of threatened and endangered sea turtles for 13 years at 53 sites across four regions of the U.S. islands in the Pacific as part of a larger study of other marine life, according to a research article released Wednesday by PLOS ONE.
The sites were located between islands, atolls and reefs in American Samoa, the Hawaiian Archipelago, the Mariana Archipelago and the Pacific Remote Island Area complex. Each site was observed every two or three years in April, using a boat towing two scuba divers 49 feet underwater who recorded the species and numbers of turtles within sight.
Researchers observed two species specifically, the green and the hawksbill turtles. Green sea turtles greatly outnumbered hawksbill across the survey area, providing further evidence of the need to protect the endangered hawksbill.
