Throwback to last year's loggerhead sea turtle tagging on Cape Verde with @FMB_CaboVerde. SnapperGPS is #Tech4Wildlife! 🐢

SnapperGPS is designed for wildlife tracking. It has already been successfully deployed on sea birds and sea turtles.

The SnapperGPS board measures 32 mm x 27 mm and weighs 2.9 g. Together with a battery and an antenna the entire tag still weighs under 10 g.

A set of SnapperGPS variants is currently being deployed on Manx Shearwaters with the Oxford Navigation Group on Skomer! This tag weighs 8.4g with smaller/lighter antennae being an option.

Here are @Al2kA, @AmandaMatthes and @JonasBchrt tagging a loggerhead sea turtle with @FMB_CaboVerde. This mama will return in 14 days to lay more eggs, so we will be able to retrieve the tag and see where she has been.🐢

Here is our current iteration with a shiny new USB-C connector. This version runs on two small button cells that allow for deployment times of multiple years! The boards in this picture are placed in enclosures that were designed to go on the back of sea turtles.

Thanks @JonasBchrt for tirelessly cycling around Oxford to test our positioning!

This is a version of our board that runs on Lithium Polymer batteries. Getting into the size regime of avian tracking here!
