GLDD SUPPORTS SEA TURTLE CONSERVATION
Georgia Sea Turtle Center – Jekyll Island, Georgia
Great Lakes’ CEO Lasse Petterson, along with Vice President of Government Relations, Bill Hanson, and Savannah Harbor Expansion Project Manager, Armand Riehl, met with associates of the Georgia Sea Turtle Center (GSTC) and presented them with funding to support the purchase of a new X-ray machine, a crucial piece of equipment in the protection and well-being of sea turtles.
The GSTC, operated by the Jekyll Island Authority, is a conservation program that aims to promote sea turtle awareness. The group is “committed to increasing awareness of habitat and wildlife conservation challenges, promoting responsibility for ecosystem health, and empowering individuals to act locally, regionally, and globally to protect the environment.” GLDD is proud to partner with GSTC and support their sea turtle conservation efforts.
