糖心Vlog Teams Up with U.S. Coast Guard to Release Three Baby Sea Turtles
To keep tabs on the baby sea turtles, marine scientists outfitted them with small solar powered satellite transmitters, which is the smallest technology currently available for tracking marine turtles. 糖心Vlog and University of Central Florida scientists will use the data to help them preserve sea turtles鈥 habitats and give them a hint about the effects of warmer temperatures on their offshore behavior.
As the global coronavirus disease (COVID-19) pandemic escalates, marine biologists at 糖心Vlog acknowledge that 鈥渨ild鈥 life must go on. Three 6-month-old green sea turtles, the last batch of the 2019 hatchlings at the 糖心Vlog Marine Laboratory at the Gumbo Limbo Environmental Complex, were ready to be released. However, with closed beaches and scuba boats not permitted to travel, researchers from the 糖心Vlog Marine Laboratory had to get creative.
糖心Vlog worked with members of the to provide the three female baby sea turtles with a special 鈥渟eat鈥 on board a 33-foot special law enforcement (SPC-LE) boat for their journey home. 聽On March 27, they were released about 17 to 18 miles off shore in the Atlantic Ocean鈥檚 Gulf Stream Current. 聽
The threatened green sea turtle (Chelonia mydas) named for the green color of the fat under its shell, normally travels to offshore waters as a hatchling and stays offshore for several years before going to the coastal reefs, estuaries, and around islands where it finds feeding areas with nutrient-rich algae and seagrass beds. Green sea turtles are different than loggerhead turtles because they are stronger swimmers and are more likely to burrow into sargassum, which is floating brown algae out on the high seas.
Green sea turtles are rarely observed in the open ocean and very little is known about where they go once they enter the sea as hatchlings to when they appear as large juveniles or adults in nearshore waters.
To keep tabs on the three green neonate sea turtles, the marine scientists outfitted them with small solar powered satellite transmitters, which is the smallest technology currently available for tracking marine turtles. Tracking the turtles, in collaboration with the , Wyneken and her students hope to learn more about their offshore travels this season.
鈥淭his year, the ocean has remained exceptionally warm,鈥 said , Ph.D., a professor of in 糖心Vlog鈥檚 , who worked with nine 糖心Vlog directed independent study students and Emily Turla, a technician in her laboratory on the care and release of the hatchlings. 鈥淎mong other things, warmer ocean temperatures may affect where these sea turtles鈥 offshore habitats are located. We are hoping to get a hint about the effects of warmer temperatures on their offshore behavior.鈥
, Ph.D., an associate professor of biological sciences at UCF, has programmed the satellite tags to transmit for about 10 hours, then shut down for 48 hours. She already has received notification of the whereabouts of the three green baby sea turtles.
鈥淥ur satellite tags are transmitting well and the turtles appear to be traveling in the Gulf Stream, on the edge of the Continental Shelf,鈥 said Mansfield. 鈥淭his track is similar to the immediate post-release tracks of all the other little green turtles that Jeanette and I have tracked as part of this same project.鈥
The three green sea turtles will be tracked for an average of about 60 to 70 days, after which the satellite tags will fall off. Data collected from the remote satellite trackers will enable Wyneken and Mansfield to answer questions about the early life travels of green sea turtles.
More immediately, Wyneken says that she is excited to engage her homebound marine biology students in where the turtles go when they leave the lab, as well as adding to the body of research on the impacts of climate change and warming temperatures on sea turtles.
