Finding the Leatherbacks
This weekend our expedition team, including Dr. Sylvia Earle, Dr. Erick Ross, Dr. George Schillinger and Kip Evans visited the turtles at the Leatherback Trust hatchery in Costa Rica.
The hatchery serves to give leatherbacks a better chance at overall survival. It begins by protecting the iconic creature’s eggs from predators, after which on-site biologists monitor the nests, checking nest temperatures which determine the sex of the turtles. When the turtles have matured, they are released to begin their migration offshore to the Central American Dome.
Successful protection of 99% of the nests started in 1993 and the hatchery started to operate in 1998-99. Although at present, population numbers are decreasing, we can expect to see numbers of leatherbacks increasing in the next few years.…
