Main Map
Sea turtles mark places where you can find signs of the sea around you. We've chosen sea turtles to mark the sites because, like sea turtles, we too need both the land and sea to live, although the ways may not be as obvious. Click on a sea turtle to see each site. You can then comment on the site, or add to the map by submitting your own signs of the sea from places you know. This first map is of North America, but you can submit signs of the sea from anywhere in the world.Recent Sites
