Introduction

A focus of this year's satellite tracking project is to compare stable isotope results with telemetry results to determine the efficacy of using stable isotopes to elucidate post-nesting migratory destinations of sea turtles. Stable isotope analysis of skin and eggshell tissue (which reflect foraging areas) will be compared with the oceanographic regions visited during satellite tracking. Stable isotope values that are consistently different for females in oceanic vs. neritic habitats lend credence to their use to infer post-nesting migratory destinations. A lack of matching between isotope values (pre-nesting habitat) and satellite tracks (post-nesting habitats) would suggest a) that loggerheads do not exhibit philopatry to foraging regions, or b) that loggerhead habitat use is too flexible to use isotopes in inferring habitat use. A consistent isotope-telemetry match among individuals would suggest that stable isotopes can be used in lieu of the more expensive satellite telemetry approach to potentially infer foraging grounds.

A second focus is to track female turtles that are potentially bycatch in the Gulf of Mexico Reef Fish Fishery bottom longline fishery. More information on this issue is summarized at www.sero.nmfs.noaa.gov/pr/TurtlesReefFish.htm

Project Partners

Mote Marine Laboratory is handling the field deployment and satellite tracking while National Marine Fisheries Service is supervising the stable isotope analysis.
