Oceans three | Santa Cruz GT Weekly

At midnight on a beach in Costa Rica, marine biologist George Shillinger affixes satellite data tags to leatherback sea turtles that have come ashore to lay their eggs. The hope is to use tag data collected from the turtles’ epic, trans-ocean migrations to help commercial fishermen sidestep the critically endangered turtles’ routes. Shillinger is one of three Bay Area scientists I profiled for this cover story, working to broker a balance between our dueling quests to conserve the ocean and harvest its resources.
