Satellite Tracked Turtles

Since 1996, the Bermuda Turtle Project has included the attachment of satellite transmitters to selected green turtles to help us understand more about their behavior on the Bermuda Platform. The satellite tags also allow us to document migratory routes taken by sea turtles when they leave the island for the next phase of their life’s journey. Starting in 2011, we attached transmitters that record GPS location data, in addition to standard satellite data, that allow a much more precise understanding of how young green turtles use Bermuda waters.

2011 Turtles

IAN – Ian, a 65.5 cm juvenile green sea turtle, was captured with an entanglement net and satellite-tagged by the Bermuda Turtle Project on August 3, 2011 at Blue Hole, Bermuda. Ian had been caught three times before, in 2003, 2007 and 2010, at Blue Hole. The site, Blue Hole, is a seagrass bed off of a nature park that fronts Castle Harbor. It is one of the sites that has been set by the project since 1978. This is one of Clay’s original study sites and it is one monitored at least once every year. Researchers believe that these immature greens in developmental habitat remain more-or-less in the same area for many years, in this case 8 years so far. The turtles was named after Dr. Ian Walker, Principle Curator of the Bermuda Aquarium, Museum and Zoo.

TIMMY – Timmy, a 48.4 cm straight carapace length juvenile green sea turtle, was captured with an entanglement net and satellite-tagged by the Bermuda Turtle Project on August 11, 2011 at an area called The Vixen, Bermuda. The turtle was named after Tim Hasselbring, the captain of the RV Endurance (the project’s main research vessel). She had been caught twice before, in 2004 and 2007, also at The Vixen.

2006 Turtle

BERMEYLAN – Bermeylan, a 28.5-inch immature green turtle, was captured with an entanglement net and satellite-tagged by the Bermuda Turtle Project on July 24, 2006, at Ferry Reach in Castle Harbor, Bermuda. The turtle had originally been tagged at this same site nearly a year prior, on August 5, 2005. Although the turtle is the approximate size at which green turtles typically depart from Bermuda and travel to feeding grounds in the Caribbean, the exact timing of the turtle’s eventual departure is unknown. The turtle may remain in Bermuda for months or even years, likely at the same site where the two captures took place. It is hoped, however, that Bermeylan will make a departure while the batteries for the satellite transmitter are still working, so that we can observe the route of travel and final destination. A previously tracked Bermuda turtle, “Bermudiana”, traveled from Bermuda to the eastern end of Cuba where she was captured (see Bermudiana track). Bermeylan was named by the participants of the International In-water Course on the Biology and Conservation of Marine Turtles which took place in Bermuda from 17 to 28 July 2006.

2003 Turtle

Peter-releasing-VixenVIXEN – Vixen is a female green turtle 71.8 cm in straight carapace length. She was first captured in Bermuda on grass beds off the west end of the island on June 13, 1997 when she was 56.4 cm in length. Her second capture was on August 7, 2003 when she was caught at a site called The Vixen, just east of her original site. The site is named after a shipwrecked vessel whose bow is still visible above the water’s surface. The turtle’s sex was determined by the hormone content of a blood sample. A genetic sample taken in 2003 will help to determine the nesting beach where she was born. Vixen is at the upper end of the size range of green turtles found in Bermuda, and it is hoped that the satellite transmitter (#11677) will document her migration to a feeding ground elsewhere in the Caribbean. The majority of recaptures of turtles tagged in Bermuda have been made off the eastern coast of Nicaragua.Vixen was satellite-tagged during a regular sampling session of the Bermuda Turtle Project. Drs. Peter and Anne Meylan, scientific directors for the project, and Jennifer Gray, project coordinator, were assisted in attaching the transmitter by students participating in the 5th International Course on Sea Turtle Biology and Conservation. The nine students taking the course this year are from Anguilla, the British Virgin Islands, the Cayman Islands, Grenada, St. Lucia, the Turks & Caicos Islands and the United States.NOTE: No points are posted on Vixen’s map for nearly the first month after the release of Vixen because of a transmitter malfunction. During this period, no dive data were received, and the locations were erratic. Fortunately, the unit started to transmit normally on September 5, 2003.

1998 Turtle

BERMUDIANA – Bermudiana , a 31-inch immature green turtle, was captured with a net and satellite-tagged by the Bermuda Turtle Project on August 5, 1998 on the seagrass beds off the northwestern end of Bermuda. She was the second-largest green turtle that has been handled by the project since it began in 1968, and thus, it was expected that she would soon be departing the Bermuda platform. About two weeks later, she did, in fact, depart and embarked on a south/southwestward course that took her to the north coast of the Dominican Republic – a journey of approximately 1500 km – in a little less than a month! She then took a westward course along the northern coasts of the Dominican Republic and Haiti and was in this area when Hurricane Georges passed by. There were no observable effects of the hurricane. Several days later, however, satellite transmissions were disrupted, and when they resumed, sensors indicated that the turtle was no longer diving. At that time, the turtle was located right off the eastern tip of Cuba. Several location signals were then received slightly inland, near the town of Baracoa, and we suspect that the turtle was captured.
