NOAA TRACKS ENDANGERED TURTLES BY SATELLITE
September 1, 2000 As part of
an international effort to transfer technology and expertise
to Caribbean nations, NOAA
Fisheries sea turtle biologists Barbara Schroeder and George
Balazs traveled to Tortuguero, Costa Rica, to train scientists
from Costa Rica, Nicaragua, and Belize in tracking endangered
hawksbill turtles using NOAA
satellites. A previous capacity-building workshop, also convened
by these two NOAA scientists, brought together participants from
Antigua, Barbados, Jamaica, Mexico, Puerto Rico, and the U.S.
Virgin Islands. Grenada is also participating in the project.

Satellite transmitters, about
the size of a Sony walkman, are attached to the carapace of the
turtles and will automatically send information about the turtle's
movements for up to two years. The tags are attached in such
a way that they will fall off the turtle, harmlessly, within
about the same time period.
The hawksbill has been listed on the
Endangered Species list since 1970 and can be found mainly in
tropical and subtropical seas of the Atlantic, Pacific and Indian
Oceans. Populations of hawksbills have been greatly reduced throughout
the globe in recent times, as a result of directed killing for
their shells, from which tortoiseshell items (jewelry, decorative
items, or whole stuffed turtles) were made. The tortoiseshell
trade has diminished, but illegal trade and legal domestic harvest
continues in some nations. The species is also impacted through
poaching and degradation of its favored habitatcoral
reef communitiesand from adverse development impacts
along nesting beaches.
The U.S. is teaming up with
Caribbean countries to gather data on the migratory habits of
hawksbill turtles after they leave their nesting beaches. The
hope is that a better understanding of the species will lead
to improved recovery and conservation programs.
"One of the essential goals of
the international research project is to clarify the extent to
which adult females inhabit foraging areas away from their nesting
beaches," said Schroeder. This information is crucial to
a scientific assessment of the merits of any management regimes
developed for the species, and will contribute to conservation,
recovery, and sound management for hawksbill turtles. The project
also aims to serve as an educational tool to enrich the understanding
of the hawksbill as a shared resource, among many nations, including
the U.S.
