Our team will conduct studies on the behavior, physiology and migration patterns of the leatherback turtles on the Pacific Coast of Costa Rica. We will help tag and identify turtles, record nest locations and help determine hatchling success. Researchers and scientists have been working with these turtles in for the past 17 years in attempt to understand the impact of human activities and pollution. This work has led to the establishment of a National Park and a Marine Biology field station.

Answers to recent questions.

1. Shibani: Yes these leatherbacks are the same species as the leatherbacks found off the coast of India. These creatures have an incredibly large range.
2. Daisy: The leatherbacks are not slimy at all. They have a smooth skin and their hard shell is smooth like hard leather but has ridges—there are beautiful creatures.
3. Ms. Purn’s Second grade: Yes, I have seen an injured leatherback. One of the adult females that came to nest while I was patrolling had only 1 rear flipper. It was just a stub, like it had been amputated. She was still trying to use it to nest making the motions, but obviously not moving much sand. She looked pretty experienced; it was not a new injury.
4. ClassIV- A nest of leatherback eggs takes between 60-75 days to hatch. The turtles lay eggs in different places along the same stretch of beach- the beach is about 3.6 Km long. Scientists put satellites on the sea turtles to track their migration and learn about their behavior at sea. Only females come to shore to nest, so their life at sea is still a bit of a mystery.
5. Desire: When a turtle “nests” that means she is emerging from the sea and comes up on the beach to dig a hole in the sand that she will lay her eggs in and then cover them.
6. Daisy: Yes, we sometimes wear headlamps to help us see in the dark.

Great Questions everyone!

We were sorry to hear you have seen an injured sea turtle, but glad that it doesn't appear to be a new wound. The students are most interested in knowing now about the food you are eating and what you are doing in your free time besides swimming in the pool and emailing!
Thanks for all the information you have been providing. We love the pictures and look on the site every day. Your time to leave is almost here and we are sad!

Fiona and Jennifer,
Thank you for the amazing "live from the field" videoconferences, photos and blog posts. Your students and colleagues were thrilled to learn so much from your remarkable experiences in such a dynamic way. Thanks to you, those precious sea turtles have captured our minds and hearts forever.

Have a safe trip home.

Hi Tanya - Thank you and your department for making sure the live from the fied conference ran so smoothly - it was the most fun I've ever had teaching, and it had nothing to do with the fact that I was doing it from a beautiful beach in Costa Rica!
