Join Earthwatch research teams in Costa Rica and New Zealand to learn about ocean life and the effects of human activities on leatherback turtles and dusky dolphins.

In Costa Rica you will have the opportunity to study leatherback sea turtles. These turtles are the oldest-living reptile, but their numbers are declining. Discover how scientists and Earthwatch teams are monitoring the nesting turtle populations to protect them. In New Zealand the acrobatic dusky dolphins attract increasing numbers of tourists, but are tourist boats and swim-with-dolphin programs hurting the dolphins?


Listen to Judy Evans, your teacher host, as she explains your mission.
