When sea turtles hatch, they depend on moonlight to find their way to the ocean. Human-caused light pollution, however, can disorient them and lead them away from the sea.

The latest video in the monthly “Outside Science (inside parks)” series tracks the young volunteers of Turtle T.H.I.S. (Teens Helping In the Seashore) near Pensacola, Florida, working to ensure baby turtles make it to the ocean at Gulf Islands National Seashore. Oh, and you'll get to see dozens of tiny turtles emerge from the sand for the first time.

Every month in 2016, the “Outside Science (inside parks)” video series will showcase ways “the next generation is getting involved in park science.” This is the fourth episode released by the National Park Service and produced by students from Colorado State University. Previous videos chronicle red tides at Cape Cod National Seashore, collecting dragonflies to study mercury levels at Great Sand Dunes National Park and Rocky Mountain National Park, and a BioBlitz at Hawai‘i Volcanoes National Park.
