The aim of this project is to monitor (i) GREEN and HAWKSBILL turtles, and (ii) INVASIVE ALGAE in Hawaii. We're particularly interested in observations of turtles with TUMORS. Macroalgae are important food source for green turtles and may also promote disease. If you see a stranded turtle call the NOAA Stranding Hotline at 808 725 5730 during business hours, after hours 808 288 5685.
