Mining sea turtle nests: An amplitude independent feature extraction method for GPR data Abstract: We use a Ground Penetrating Radar (GPR) to localize eggs of sea turtles laid in sand. GPR technology has been developed to detect subsurface structures, and successfully applied in archeology, civil engineering, and demining.
